This video is EXACTLY what i wanted. More of a natural feeling. Great visual representation of what the motor is giving with the spreadsheet. Thanks!!!
Thanks, I have a 250 watt Bafang, max allowed in UK and most of Europe. I have tuned it to overpower it in the higher assistance levels and less for level routes, even the 250 watt version you can sometimes be surprised when the power kicks in. My ammeter often shows a current of 800 watts when climbing off road, and even after 3 years the motor and battery are fine.
My wife'sBBS02 came out of the box wth the same current percentages attributed to each power level (1-9) which meant that it was producing 600 Watts (12.48Amps : 52% of 24A) in power level 1. It was a bit of a beast on the first test ride and clocked 35mph on the flat! Thought this setup might scare her so set max current to 20 amps an toned down power levels 1-9 now (2 years later) have current % at 0=0, 1= 8%(1.6A), 2=11%(2.2A), 3=14(2.8A), 4=17%(3.4A), 5=30%(6A), 6=50%(10A), 7=70%(14A), 8=90%(18A) and max 9=100%(20A) Not if you multiply Amps(A) by nominal battery volts (48) you will have the power for each power level setting which equates to 1 =77W, 2=105W, 3=134W, 4=163W, 5=288W, 6=480W, 7=672W, 8=864W and 9=960W. My kit came out of the box with a much softer set of lower power levels and have now ended up setting as per wifes. Both have been utterly reliable and regularly achieve 70 miles range fron a Hailong 48V 17.5A (840Wh) battery. Throtles have been changed from "by displays command" to power level 8 so there will always be up to 864Watts of powet to get you out of trouble. We use them mostly on motorhome holidays where we can charge both batteriesin an evening using free solar power. Great series of videos that inspired me to build our e-bikes. Wife said she wasn't old enough for an e-bike,but its now her most treasured posession!
Hello Luke! I watched several of your videos before upgrading my bike with a bbs02b 750W. Thank you! Keep the good work! Everybody has a different biking style. I am a fan of efficient use of energy which comes down to 3 principles (1. Bike in a way so that you almost don't use the brakes. 2. Make use of gravity. 3. Don't be too fast unless you need to). All my speed limits are set to 100% (this is not what affects efficiency, your biking style does). My starting current is set to 7% (was at 20% first but then starts felt too energetic). I eventually concluded that 9 levels are too many for my style, so I switched to 5 levels, set as: 10%, 20%, 30%, 60%, 100%. I use mostly levels 1,2,3, very rarely - level 4 and almost never - level 5. On my commuting daily trip there are hills but not very steep. If readers of this nice channel would like to try my settings and share opinions, I would be pleased. Cheers everybody!
i would like to try your settings, can you post up here? like you i too use 5 x PAS levels. am i right in saying when using 5 PAS levels it chooses assist 1, 3,5 7 & 9?
How would you program it to nexus 3? just changed by hub from 7 to 3 as this is typical city bike, but getting confused on the power settings. I also only use 1-3 gears, rarely 4 as bike is 2 fast. So trying to figure proper settings for max speed 45 and 3 gear shift.
Thanks I came here to learn how to slow my 750W down! Its too fast for the commute and I dont want to break local laws, plus I want to keep everyone safe. I like the idea of extended life for all parts, great thinking!
I had been struggling with the settings until I saw this video, thank you! Your settings have tamed the wild steed and I no longer feel like I'm at the rodeo! The only issue I have now is the long power pause of the gear shift and wondering if there is any way to remedy that.
Hi William, I'm happy to be helpful About shifting, the only suggestion I can give is this: you can shift while pedaling, if you do it at the right moment. (works only with Bafang, not with Tongsheng) When pedaling, the motor will increasingly provide some Watt, you can see it from the display. Let's say it goes up to 750W... at a certain moment, when the right speed is reached for that level, the Watt provided will be reduced, leaving more responsibility to your legs. THIS is the right moment to shift while pedaling, cause the chain will just sustain your legs' force, like on a normal bike. As soon as you shift, or half a second later, the motor will start to help you again! Try this out 👍
I also dropped my 750w BBS02 down to make it smoother. I ride a fair amount in the city and just crossing the street was kind of a ridiculous exercise. If I were to buy another one, I'd probably get a 500w version - it would be plenty of power. I also got a 19 AH battery and with I'd never gotten something so big and heavy. I've never used more than about 60% in a single ride, even in the Alps. This video really helped me understand how to accomplish this, but I used the Speed Android app and my phone.
I've been mountain biking for almost 10yrd now and I also had to lower the power settings to get more natural feel I have a bbs02750w and when I first got it level one was at 30% power so the bike would be really fast of the line I'm at 12% on level 1 now,it also conserves more battery this way
I modified my settings to 9 levels and upped my speed assistance to 28mph. This system is working with a 10-speed cassette and changing it to 9 levels of assistance, it works much better and smoother compared when it was on 5 levels of PAS.
Awesome, thanks for sharing that with us! I'm looking at building one with a 750W motor and a huge 48V 45ah triangle battery, and seeing these settings and curves should help me get the most range out of it and also make it easier to control the bike when not needing to go too hard.
Hey good luck on your project. Tire thickness makes a massive difference 1.95” vs 2.25” can produce very different ranges. Make sure the bottom bracket will fit the mid drive.
I modified this to keep a constant speed with varying power levels. Great! Thank you so much for this. Way better! In detail. I tend to ride with the same cadence no matter what. Since you adjust your speed with gears, not cadence (as lower cadences are less "efficient" for your legs), I set PAS 1-8 speed to 65 (upper comfortable limit for me). PAS 9 is 100% speed. This feels much more natural, as I can pedal as fast as I want, but control the assistance. If I want less RPM I change to a higher gear with lower PAS. My settings are as follows: 0: 0, 0 1: 11, 65 2: 24, 65 3: 36, 65 4: 49, 65 5: 62, 65 6: 75, 65 7: 87, 65 8: 100, 65 9: 100, 100 With throttle set to current and PAS 9, I can quickly overtake without spamming the PAS adjuster. The first setting is great for a little push when cruising, but you don't really need any more to keep your speed. Set the speed to a percentage to where you're just bearly uncomfortable. Above a certain cadence you start to loose power, so there is a sweet spot (I would say between 60-90rpm) 65% of 130rpm should be around 87rpm.
I have a lunatic 1500w BBS02 and I downtuned it to 600w for my Quest. I didn't trust that anything higher than 600w wouldn't break my $6k bicycle (and I can still maintain 36mph on flats).
Hey Mik, thanks for sharing! Unfortunately it's not that simple. Those who chose BBS02 are looking for something that torque sensing cannot offer, like the possibility to arrive at work not sweating, or to overcome some leg disability... but they still don't want to risk their lives in order to have those possibilities 😅 at least, with the 750W version. of course if someone doesn't need constant assistance, torque sensing bikes and kits are perfect without any need to tweak!
On my BBS02b I changed the 'throttle handle' thumb throttle from current to speed and it made it much smoother and linear. Before when set to speed it was just like an on/off switch. thanks for the video 👌
Hi- you say you changed it "from current TO speed", but then say "Before when set to speed"... this contradictory. What setting did you end up using? Thanks.
@@garyfisk370 Hello Gary. Yes i got that wrong didnt I. My BBS02 is now set to speed and that seems to give the smoothest throttle. If you try 'speed' under no load (with the rear wheel lifted of the ground) then the thumb throttle is really smooth and variable, incremental, progressive, whatever the word is, but under load as in normal riding this is less obvious but still seems smoother than using 'current'. My advice is try both. Conversely on my BBSHD I have it set to current as that seems to give the better response in actual riding. (BBSHD with the rear wheel lifted under no load and using 'speed' then the throttle seems really controllable from barely spinning to full speed as you move the thumb throttle but this doesnt translate to actual riding when the motor is under load). So try both.
Hey man. Before I bought my BBS 02 motor, I watched some of your videos. They really helped in the decision and I absolutely love the Bafang motor. And yeah I agree, the power/kick on lower settings is a bit too much for a city rider like me. Gonna get that USB cable and do some tweaking. Thanks mate
Yeah, factory default setting is too strong. I worked on my settings few times and now im very satisfied. It reacts the way i wanted. But truth is, torqe sensor still wins :) but i made 10000km on my bbs02 350W and it still works like first day.
Great video Luke - exactly what I was looking for. I just converted to a Bfang mid 250w which run just fine from level 1-9. Upon converting another bike to 500w - the power seemed excessive even at low levels, and my concern is now understanding how to respect the CH ebike limits. Look forward to watching your other video see what else I need to learn. E vedo che hai tovato la bellisima zona del lago di St. Sulpice!
The great advantage of the BBS02 is the extent to which its characteristics can be adjusted to meet the needs of the rider. Changing power levels and rates has a dramatic effect on the how the bike reacts to rider inputs. I also use an an Eggrider that offers the ability to not only have 2 separate provides but also to make changes essentially anywhere. I found that the process of fine tuning required many changes and took a good deal of experimenting on the road - ideal with the Eggrider. However you do it, you will not get the full benefit of the BBS02 without controller tuning...
I hope the Eggrider is improved over the original. Mine stopped working when the bluetooth dongle developed a short (no Eggrider display back then). I have since the original version started using a phone app called Speeed. Bottom line is you have to fiddle with stock settings to get your perfect ride, no matter how you do it.
Very helpful video, thanks! One question, though, I see here, and in other BBSTool videos for the Bafang 750w mid drive motors, the 100% current limit is at around 24A, with 48v battery, this is just over 1100W... no issue with this!? Why not reduce the limit to 16A and protect the motor?
Thanks for this one Luke. I too have a Bafang 750w 48v kit installed on my Tern link D8 folder. So instead of 10%, 20, 35, 50 and so on from level 1. I have to reprogram it again to my specific riding preference and battery management range to 8%, 14, 20, 30, 45, 60, 75, 85, and 98 respectively. Great vid man.
I have a setting on mine and it's just a simple lectric that has the initial torque setting. Of course I turned mine up not down but it doesn't have the gear reduction as yours does.
do it x 1.44 for each value. I have mine limited to 18 A And it goes like this 1 - 1.8A 100%speed 2 - 2.52A 100% 3 - 3.6A 100% and so on So times 1.8A x 1.44 as as starting value (10% of the total 18Amps) and go up. Ending assist level 9 with 18A 100% speed or lower speed percentage if you need so.
Bella Luke, innanzitutto ti ho seguito dalle tue prime pubblicazioni e sono contento del progresso che stai facendo nelle visualizzazioni ed iscrizioni, ben per te :) Ho voluto provare la tua configurazione ed effettivamente funziona mooolto meglio rispetto alla default config, diciamo che l'assistenza è molto più graduale e naturale. Toglimi un dubbio: se io imposto a 5 livelli di pedalata mi confermi che il motore fa riferimento ai livelli 0-1-3-5-7-9? Poi, credi sia il caso di aprire la calottina (dalla parte destra del motore) per pulire e re-ingrassare la parte meccanica, quella delle delle ghiere, per intenderci? credi sia safe provare a farlo o rischio qualcosa? Tu l'hai mai fatto? Grazie di averci portato la tua esperienza, seguirò eventuali aggiornamenti 🙂
Bella Luca, grazie per la fiducia nel canale 🫶 intanto ti confermo i livelli da 1 a 5 come li hai elencati! quanto a reingrassare il motore, è una buona pratica di manutenzione. io al momento non ci ho ancora provato, conto di farlo verso i 5000km. se cerchi ci saranno sicuramente dei video a riguardo, ma in effetti prendo spunto dalla domanda per un video futuro grazie del feedback! 🤜🤛
I have installed 2 Bafang 750 mid drive kits now and neither of them have EVER made my bike wheelie or go out of control. Recently I detuned both bikes to more gradually deliver power on the onset of peddling. Mostly to lessen the feel of the assist. But, not for the over dramatized wheelie or out of control thing. Not even on setting 9 will they do wheelies. You have the 42 tooth front sprocket? If you do, and this is probably why you are doing wheelies. Most riders should be using 52t front sprockets as the smaller sprockets are for mountain bike set-ups.
The best thing I bought was the eggridder V2 display for my bafang mid-drive motors I can change all my settings from my phone even when I'm out on a ride it's a lot better than the cable to configure your controller settings 😀
hey man! I heard about it, it seems like a super cool thing! maybe not the one for me specifically: I'm more like "study it at home and then just drive the result", but it's definitely better if you want to test things "live", like you say 💪
@@LukeLorusso I agree when I'm out I don't mess around with the settings like you I just study it at home then apply my changes for my next ride infact I've not changed them since
Hello Luke! Great video mate, I'm going to buy a bafang 750w with a 48V 20ah battery, it will be a good one? I just need help with the screen, I saw the 500c display where we have the 9 levels assists. But I really like a small one called sw102, with 5 levels. To follow you, the 9 levels converted to 5 will be like "1-3-5-7-9"? Thanks a lot for sharing how to update the motor
Luke, have you tried looking at the eggrider? I don't have access to a computer, only an Android tablet, phone. I just purchased a 759 w bbso02, and eggrider and would love to apply your downgrade.
I too purchased the Eggrider and like the fact that you can change settings on the road anywhere anytime. Not only that but you can have two different setups at the push of a button.
I use 56v 14s 2p battery packs on my 48v Bafang BBS02 750W. I've even used 60v packs but it can shut down for Error #07 overvoltage on the display if anything going over 61.5v as it will flag a 07 error. After the initial 2018 Bafang purchase and 1500 miles as of Oct. 2023, I may have burned out one of the MOSFETs (error code #12) current sensor abnormality. I don't know for sure if it was overvoltage that caused it but I might downsize the wattage next time just to keep it safer on the 56v batteries.
i have mine set as 100% for allPas 1-9 in the speed section. this way i have max power on the throttle if i need it in a pinch. Any thoughts Luke ? BTW great to see videos on fine tuning, well done.
Under the throttle section of the programing app, you can change the pedal assist setting from "given by display command" to 9 or whatever level you prefer to lock your throttle level at. This way your throttle is always set to 9 (100%) without affecting any of the peddle assist %.
Hi Luke, great video! Thank you! My wife's bike is the BBS01 250W 48V with a small display with only 0-5 PAS (BNS136) do I only need to program the first 5 levels and leave 6-9 empty? Thank you for any insights
Good video, thanks for posting. Is there a way to speed up the PAS response? I have gone through all of the settings and now my throttle works much smoother and the PAS levels are just what I want. However, the Pedal Assist comes on way too slowly, only after 2 complete revolutions of the pedals. Is there a setting that controls this? Thank you!
I followed another guys settings so that power was 5, 10, 15% etc increases - with throttle tied into pedal assist 8 (80%) for a quick burst if you need it
I see... yeah mine it's a simple suggestion: everyone should personalize the settings based on their needs, there's no right or wrong, just endless permutations of values 😅 I had a need and solved it this way, but anyone should tune it differently for different needs: I just wanted to show how 😉
I did something similar to my sabvoton build. but what i did change was that i nerfed my phase amps a lot rather than battery amps. before i had great acceleration and could go up any hill but my controller was hammering my battery at any speeds. after i lowered phase amps it uses a lot less battery at lower speeds but i still have decent mid t high end power and speed. it moves pretty slowly from a standstill or going uphill at low speeds but then thats countered by pedalling through it. I almost doubled my range on my route to work (its an offroad footpath with about 0.5 miles of road at the end)
Ciao Luke. Ho visto tutti i video che hai pubblicato e sono tutti molto interessanti, ti fanno venire la voglia di fare esperimenti e costruire un'ebike. Infatti sto valutando se fare l'upgrade ad una vecchia mtb che ho ferma e sono intrigato dal kit Tongsheng. La bici ha 3 corone davanti e 7 rapporti dietro e facendo l'upgrade la diventerebbe monocorona, non mi è chiaro quanti denti sarebbe meglio avere. Inoltre ho visto che sulla tua bici con il kit Tongsheng sei riuscito a mantenere due corone davanti. Penso che avendo pochi rapporti dietro riuscire a mantenere una corona in più davanti renda la bici versatile, l'obbiettivo sarebbe poi quello di usarla per fare qualche giro su sterrato in montagna in salita. Hai qualche suggerimento? Grazie!
ciao Filippo, butto qui qualche pensiero sperando che siano utili. Si, ho messo la doppia corona (44 e 48) ma quella grande per il motore da 500W era troppo alta, il motore faceva fatica, quindi l'ho rimossa e ho mantenuto quella da 44. In generale per un motore da 500W 44T è "ok", dovresti scendere di dentatura se vuoi attaccare salire molto ripide, ma più di 44 per esperienza personale non serve. Con il Bafang sarebbe un'altra storia, esendo a cadenza: puoi arrivare a velocità più alte con una dentatura più ampia...meglio però disporre di 750w in tal caso. anche io ho 7 rapporti sul tongsheng e credo siano sufficienti!
I cut my 350 watt hub to 7 amps & it goes to 15 amps. I never thought I would us 0-9 settings, but I tried it & now use it all the time. I'm pretty happy getting up to 12 mph. I like using the bike to aid fitness. The temptation is to overdue it & suffer injury.
I believe you are right and wrong at the same time. You seem technical so to share... Air drag grows at the square of velocity Power level required grows at the 'cube of velocity" Translation: You want an exponential power delivery curve. You are right in that the factory programming of your BBS02 was way off for good power modulation at low speed. True But, I am a BBSHD 52V 19.2 amp-hr owner on two bikes with 1700 watt maximum. 58.8v (battery full charge) X 30 amp = 1700 watts Yes, I rarely use the 1700 watts but I do 'sometimes' for riding 30mph+ for short periods out on fast roads. Using the Bafang Configuration tool... I start with very incremental lower power settings for over 1/2 of my power settings...I use 5 power setting. Then I ramp up to 70% power for power setting 4 and 100% power at power setting 5. 95% of my riding is in power settings 0-3. I program power setting zero to apply 10 percent of power. I do like to race on occasion. I also have had elite road cyclists...no motor hold my wheel at 30 mph so I like to have power to ride fast. What most users will appreciate is 'granularity' at lower power settings to fine tune power delivery at speeds from say 0-24mph or so. Above that because power required is the cube of velocity, you want exponentially more power to propel the bike faster. So power delivery, again in my opinion, should be non-linear, not linear. So you are correct in more gradation at lower speeds but as you get into higher power assist, this should not be linear 'in my opinion'. More of your power settings should be smaller spaced at lower assist levels with a much bigger jump at highest power settings. My opinion. Big power is a good thing on an ebike 'when needed'. But also as your video suggests, so it granularity of power settings at lower speeds to make the bike more docile and natural as you say at speeds that are most commonly ridden. A very good video and wanted to share my opinion only. Completely agree the Bafang Configuration Tool should be used to reprogram the Bafang controller. I also like having my throttle be 100% available in each power setting....and slower pedal assist ramp up as you mentioned. Cheers from America where speed is scrutinized less than Europe where you have a 15mph speed limit on ebikes. Police in America could really care less about ebike power if we ride respectfully which I always do. I ride to the speed of my surroundings and don't abuse the power I have. PS and what fabio said below. 100% speed for each power assist level. Reason is, let the power available limit speed and not put an artificial ceiling on speed and limit power assist.
Hi thanks for your input! I have a question about only using 5 levels of PAS, when programing do you not put any values in for 6-9? So only 0-5 have data? Our display only has the 0-5 PAS option (BN136) so I'm wanting to work with that. Thanks again
I would basically want each assistance level to be a certain amount of power instead of cutting off at a certain speed. Well I got to get mine installed before I can start playing with the settings.
I also wanted this. And so I did. Change the Speed Limit to the maximum level you can comfortably pedal. Mine is 65% (about 85-90rpm). Then just change to a linear current increase for each PAS mode (except for 9 which is 100% power at 100% rpm). This way, you can pedal as fast as you'd like (or slow) and adjust the PAS to get more or less assistance. I am however considering doing a logarithmic power curve instead of a linear one, mostly to give me more choice for lower power levels. Over about 500W you won't really add anything, so any PAS level above this is pretty much redundant. I'm thinking something like. Power in watts. 75W 130W 200W 280W 350W 500W 750W Max.
i droped mine from 25A to 15 A and goes fenomenal to the moment , and also im using the App Speeed from bafang , on my phone , with this App dont needs a laptop to do changes
I did the same with the assist, then gave the throttle 100% Now that i'm used to it i wish California would allow the 1000 hd on the street, especially when dealing with traffic and long distance commutes.. i did pick up a 52v 25ah battery and can hit 42mph full throttle while peddling as fast as possessable, but i wish i could hold 35+ mph with out having to peddle my ass off !!!
Thanks for sharing valuable information. Do you ever have to worry about the legality of 750w? I'm more worried about accidents and insurance claims than occasional police checks. Here in Austria also the max power is limited to 600w and the continuous power to 250w. I'm not even sure if limiting the power and speed in the controller would make it legal. I'm going to receive my 750w kit soon and don't care much anyway.
Hey thanks for your question! Where I live it's possible to have powerful ebikes (mopeds, up to a certain W limit) if you comply with the rules: having a licence plate, driving licence, insurance and wear a certified helmet. Unfortunately, if a custom 750W build isn't legal in some places, downgrading it won't make it suddently legal... I believe those motors are made for cargo bikes, and that's why they are so powerful. If someone really wants to use one of them for personal transportation, here I show some options to make it "closer" to a less powerful kit in terms of behaviour and personal safety... but not in terms of the law.
@@LukeLorusso Many thanks for your answer! I understand you have to keep it legally "correct" here. I'm going to limit the speed and power and use it as a bicycle (not a freaking moped) responsibly regardless of idiotic laws. Where I live hills are too steep for everyday commute with a 250w bike. After all, we are doing everyone a favor by not driving cars, and laws are supposed to support the idea! Stay safe
@@persiathiest1963 Stay active and vocal to change those idiotic laws! Do you get a ticket if you don't use your brakes going down a hill? 🤦 There's absolutely no reason an adult can't have a personal e bike any damn way they want and follow common sense traffic laws. (Power and control!) Let's never forget what these idiots did to us during the "pandemic"
The legal maximum motor watts in my state is LESS THAN 750, so 750 is technically illegal. Does your method enable you to make your motor 749 Watts & legal?
hi thanks for your mid motors video series , they helped me a lot . want to ask if I order a BBS02b 500W . can it be upgraded the same way to 750W ? Do both have the same hardware ?
hey! that's not something you could do first of all, 500W has 2 variants: 36V and 48V, while the 750W only exists in the 48V variant. if you take the two 48V versions, what's different is not the motor itself but the controller, which ideally you could replace, but I can't see why not buying the 750W directly instead of messing with the 500W one
Oh i was not aware that they have different controllers, i thought it can be reprogammed without hw change . yes i am planning to buy the 48v version. I actually assumed 500w will be enough for me at the moment , but would like to have the possibilty of having more power when needed. Does actually the 750w act after downgrading the same like original 500w or 350w motor or is there still differerences ?
@@ahmed4052 you can surely downgrade it, now I'm not sure if there's an actual config to make it behave "exactly" like a 500W or 350W, but with these setting I'm showing in the video, at lower levels it feels innocuous :)
Hello my friend, i'm John from Portugal, i like tour vídeo, and i need to ask if is possible send the link for the program download to so i can do the same in my bafang bbs02b 750W Thanks
Hi! Check this video at minute 8:08 ruclips.net/video/0j5WWCyUqoI/видео.html where I answer it I'm also soon making a new video about Tongsheng which may change things :)
Hi! As I explained in the previous video ruclips.net/video/Cy2RFpWLeZ4/видео.html I've found it on Amazon, but you can find it also on other market places
Hi Luke, thanks for sharing! If you have an Android phone, take a look at "Speeed" by Marcin Kompa. Yes, spelled with three "E"s. I've used it for a couple of months on a BBS02B and a BBSHD. It does everything the Windows app can do, only you can do it anywhere. I think it's really awesome. I'm not affiliated with Bafang, Mr. Kompa or Android, in case you are wondering.
Hey Herald! Thanks for sharing. I actually tried that app and surprisingly, even if I changed just a couple of values, that app also changed parameters that I didn't intend to change... I don't remember which one but that made me think. I know it cause I read the values with my PC after flashing from the app. I'll stay with the PC method, also cause I don't change settings that much, but it's surely a good on-the-go alternative :)
@@LukeLorusso That happened to me, as well. In my case, my mistake was not using the "READ ALL" button on the "Home" tab before doing any editing. It wrote the apps default values, which I had edited instead of the controller values. Aside from this incident, I never had any trouble. Usability isn't perfect, to be sure, but I think you have to do that on the Windows app as well. Now, I usually edit the values in the *.el files or load the *.el files and edit them in the app before flashing, so I might have missed unreliable reading from controller incidents. I also only use "WRITE ALL" from the "home" tab, not the "write" buttons from the detail screens, because I am uncertain if they write everything or just the values from the specific tab.
Way too much math! I just did the adjusments in a fashion that seemed more linear then used the "SPEEED" app (on my phone) to adjust programming on the fly until I got it right for me. My 02 is set up to be "class 1" and I have a tiny 6AH battery so 18 amps was more than enough to maintain 20 mph on flats and still climb hills with ease plus I get better range from my tiny battery. An added benefit is that at 18 amps the 02 is virtually bullet proof reliable.
I guess yes, absolutely! consider that these are % values, so on an HD 1KW they will translate to almost a 25% boost on levels compared to the 02 750W, but they'll sure make your experience way better overall ✌️ ...not sure about the BAC855 thing btw 🤔 can you still use the programming tool with it?
Ciao, scusami ma se uno vuole depotenziare ad esempio un 350w via software e portarlo a 250w, nel caso dovessero sequestrare il mezzo e per fare delle verifiche, si accorgerebbero che originariamente era un 350w, oppure pensano che sia un vero 250w? Grazie
That Computer bafang configuration tool is way complicated.. I used my programming USB cable / w/adapter DataCable to usbC / Then downloaded an Android APP called "SPEEED" on my phone.. I can do everything on the fly with this simple Android APP on my phone..
that's the BBS02B, which apparently will survive alongside the newer one. BTW some early experiments (I didn't test it) are showing that replacing the new controller with the old one allows the customizations to be done on the newer one two
Luke pensi che bbo2 750 va bene per un rock rider 520 explorer dechatlon oppure. Dovrei prendere quello nuovo nuovo 625 1000w. Perché ho molte salite per arrivare a casa. Grazie
Ciao! non ho mai provato il nuovo 625 quindi non posso dirti in merito... ma quello che posso certamente dirti è che 1000w è mostruosamente troppo... a meno che non guidi una bici cargo, o pesi più di 150kg. I rapporti sono spesso più importanti dei W! un rapporto largo diretto e stretto avanti fa fare salite incredibili anche a 500W Il consiglio che posso darti è: risparmia sul motore e spendi in batteria! almeno 48V 17Ah
Thank you! My battery lasts for 100km... but the throttle is so aggressive from the start that I cant use pedals in combo or tell the difference in assist levels😅 (why do they even exist in face of custom software or instead of factory linear/optimally tuned throttle???).
my motor always heat up after 4hours of usage or 1hr during sunny days. If you set the controller amp limit from 25 to 18 or 20? Will it lessen the heat issue?
This program from Bafang is in Windows only? I too do not want all the power the motor has. I just want some help on hills and head winds. Thanks for the video. I gave it a thumbs up too.
hey! yes this one is for Windows only. the other possibility is to use an Android app (which is not equivalent) that allows you to read an flash settings with an OTG adapter and the same USB flash cable: play.google.com/store/apps/details?id=com.mkopa.speeed remember to read the default settings and save them before starting playing with the app 👍

I have the 1000W . The bike feels very jerky and cheap They had to use a torque sensor to adjust power to your needs. But this cheap product lacks it.😢
au début je pensais parement, chez moi dans le sud d'Italie. Ici en Suisse par contre... il y a quasiment toujours des montées compliquées aussi en marchant ! du coup honnêtement, pour ce cas las, je trouve que le 750W aide beaucoup mieux
I like my bafang 750 just as it is.. I use 3 assist levels... not 9. You need to click.all the time.. like playing playstation. I use assists 2 and 3... never 1. Its too weak
Kind of silly to ride an illegal motor (most places) and downgrade to what a 250W would give you. I fitted a 250W kit for mtb trail it does the job perfectly. And if i get in zn accident on the road and they check my motor i won't have legal issues. Riding with 3 times the power that's legal on the road is too many liabilities to me
as I said in various videos, not everywhere it's illegal to drive a motor higher than 250W nominal. hence, there might be a LOT of people (say in north america) who can ride 750W motors and still feel unsafe with the stock configuration. I'm happy about your 250W choice, I also believe it does the job (in flat areas), but those videos are meant for international viewers, with different legislations. please, always mind this
Cry baby, I have the 1000 watt and love it. If you're geared very high I can see the torque being crazy but 46 tooth in front and 26 in back isn't wheelie ville. If you want a torque sensing get the m365 mid drive. Geesh
I don't want ever ghost pedaling, I want to pedal all the time so mostly would keep in level 1....I want the battery to last for the longest mile. I can't believe parents allowed two young girls that never rode an ebike before and got one girl killed in CA!!!! What gears do you have in the back??? I am going to put the 12 gear cassette...
CUT THE GREY PAS WIRE!!! PAS IS USELESS.... Make your bike a throttle only bike! Then those PAS settings will be the power settings of the throttle!! You ride your bike like a bike and add power when and where you need it! I've built over 20 bikes and the ones I set up like this for people they couldn't belive how much they loved thier bikes again.
Can you provide a link to show me where in the programing software that I can disable the PAS? If so I will test a drive without the grey PAS wire cut and see if it behaves the same as my set up.

Where is the logic here? Instead of buying a 750W motor, you had to buy a 250W one and not mess with it. You paid for a 750W motor that you don't use all of. It does not make sense
the logic is all there, you might want to re-watch the content paying a bit more attention to what it's said. those mods don't transform the kit into a 250w motor, and all the power of the motor is still there. what changes is its distribution throughout the levels. maybe the follow up will clarify even further: ruclips.net/video/HEGihE0BZEo/видео.html
This video is EXACTLY what i wanted. More of a natural feeling. Great visual representation of what the motor is giving with the spreadsheet. Thanks!!!
using your tune for about a month now. works perfect with my 9sp thank you.
Thanks, I have a 250 watt Bafang, max allowed in UK and most of Europe. I have tuned it to overpower it in the higher assistance levels and less for level routes, even the 250 watt version you can sometimes be surprised when the power kicks in.
My ammeter often shows a current of 800 watts when climbing off road, and even after 3 years the motor and battery are fine.
thanks for this John, so you actually feel confident advising a 250W Bafang kit. nice to know! :)
My wife'sBBS02 came out of the box wth the same current percentages attributed to each power level (1-9) which meant that it was producing 600 Watts (12.48Amps : 52% of 24A) in power level 1. It was a bit of a beast on the first test ride and clocked 35mph on the flat!
Thought this setup might scare her so set max current to 20 amps an toned down power levels 1-9 now (2 years later) have current % at 0=0, 1= 8%(1.6A), 2=11%(2.2A), 3=14(2.8A), 4=17%(3.4A), 5=30%(6A), 6=50%(10A), 7=70%(14A), 8=90%(18A) and max 9=100%(20A) Not if you multiply Amps(A) by nominal battery volts (48) you will have the power for each power level setting which equates to 1 =77W, 2=105W, 3=134W, 4=163W, 5=288W, 6=480W, 7=672W, 8=864W and 9=960W. My kit came out of the box with a much softer set of lower power levels and have now ended up setting as per wifes. Both have been utterly reliable and regularly achieve 70 miles range fron a Hailong 48V 17.5A (840Wh) battery. Throtles have been changed from "by displays command" to power level 8 so there will always be up to 864Watts of powet to get you out of trouble. We use them mostly on motorhome holidays where we can charge both batteriesin an evening using free solar power.
Great series of videos that inspired me to build our e-bikes. Wife said she wasn't old enough for an e-bike,but its now her most treasured posession!
Hello Luke! I watched several of your videos before upgrading my bike with a bbs02b 750W. Thank you! Keep the good work! Everybody has a different biking style. I am a fan of efficient use of energy which comes down to 3 principles (1. Bike in a way so that you almost don't use the brakes. 2. Make use of gravity. 3. Don't be too fast unless you need to). All my speed limits are set to 100% (this is not what affects efficiency, your biking style does). My starting current is set to 7% (was at 20% first but then starts felt too energetic). I eventually concluded that 9 levels are too many for my style, so I switched to 5 levels, set as: 10%, 20%, 30%, 60%, 100%. I use mostly levels 1,2,3, very rarely - level 4 and almost never - level 5. On my commuting daily trip there are hills but not very steep. If readers of this nice channel would like to try my settings and share opinions, I would be pleased. Cheers everybody!
Hey man! I agree 99% of what you said, thanks for sharing your experience 💪
i would like to try your settings, can you post up here? like you i too use 5 x PAS levels. am i right in saying when using 5 PAS levels it chooses assist 1, 3,5 7 & 9?

How would you program it to nexus 3? just changed by hub from 7 to 3 as this is typical city bike, but getting confused on the power settings. I also only use 1-3 gears, rarely 4 as bike is 2 fast. So trying to figure proper settings for max speed 45 and 3 gear shift.
On the other hand, I live in steep area with bears, so a strong start is needed😅🔥💪
Luke would you mind doing a deeper dive video into the other various settings so we can better understand their function?
Thanks I came here to learn how to slow my 750W down! Its too fast for the commute and I dont want to break local laws, plus I want to keep everyone safe. I like the idea of extended life for all parts, great thinking!
I had been struggling with the settings until I saw this video, thank you!
Your settings have tamed the wild steed and I no longer feel like I'm at the rodeo!
The only issue I have now is the long power pause of the gear shift and wondering if there
is any way to remedy that.
Hi William, I'm happy to be helpful
About shifting, the only suggestion I can give is this: you can shift while pedaling, if you do it at the right moment.
(works only with Bafang, not with Tongsheng) When pedaling, the motor will increasingly provide some Watt, you can see it from the display. Let's say it goes up to 750W... at a certain moment, when the right speed is reached for that level, the Watt provided will be reduced, leaving more responsibility to your legs. THIS is the right moment to shift while pedaling, cause the chain will just sustain your legs' force, like on a normal bike. As soon as you shift, or half a second later, the motor will start to help you again!
Try this out 👍
I also dropped my 750w BBS02 down to make it smoother. I ride a fair amount in the city and just crossing the street was kind of a ridiculous exercise. If I were to buy another one, I'd probably get a 500w version - it would be plenty of power. I also got a 19 AH battery and with I'd never gotten something so big and heavy. I've never used more than about 60% in a single ride, even in the Alps. This video really helped me understand how to accomplish this, but I used the Speed Android app and my phone.
Could you tell me more about choosing the 500/750. My use will be mainly shorter rides in hilly areas.
@@djVania08 750 is better. More efficient.
I think you could be onto something here, like most I went with max power, although after seeing your video, I changed my view. 👍
I've been mountain biking for almost 10yrd now and I also had to lower the power settings to get more natural feel
I have a bbs02750w and when I first got it level one was at 30% power so the bike would be really fast of the line I'm at 12% on level 1 now,it also conserves more battery this way
I modified my settings to 9 levels and upped my speed assistance to 28mph. This system is working with a 10-speed cassette and changing it to 9 levels of assistance, it works much better and smoother compared when it was on 5 levels of PAS.
Awesome, thanks for sharing that with us! I'm looking at building one with a 750W motor and a huge 48V 45ah triangle battery, and seeing these settings and curves should help me get the most range out of it and also make it easier to control the bike when not needing to go too hard.
Hey good luck on your project. Tire thickness makes a massive difference 1.95” vs 2.25” can produce very different ranges.
Make sure the bottom bracket will fit the mid drive.
Thanks!
I modified this to keep a constant speed with varying power levels. Great!
Thank you so much for this. Way better!
In detail. I tend to ride with the same cadence no matter what. Since you adjust your speed with gears, not cadence (as lower cadences are less "efficient" for your legs), I set PAS 1-8 speed to 65 (upper comfortable limit for me). PAS 9 is 100% speed. This feels much more natural, as I can pedal as fast as I want, but control the assistance. If I want less RPM I change to a higher gear with lower PAS.
My settings are as follows:
0: 0, 0
1: 11, 65
2: 24, 65
3: 36, 65
4: 49, 65
5: 62, 65
6: 75, 65
7: 87, 65
8: 100, 65
9: 100, 100
With throttle set to current and PAS 9, I can quickly overtake without spamming the PAS adjuster.
The first setting is great for a little push when cruising, but you don't really need any more to keep your speed.
Set the speed to a percentage to where you're just bearly uncomfortable. Above a certain cadence you start to loose power, so there is a sweet spot (I would say between 60-90rpm)
65% of 130rpm should be around 87rpm.
I have a lunatic 1500w BBS02 and I downtuned it to 600w for my Quest. I didn't trust that anything higher than 600w wouldn't break my $6k bicycle (and I can still maintain 36mph on flats).
this is the reason I opted for tht torque sensing tongsheng TSDZ2B instad of the BBS02
Hey Mik, thanks for sharing!
Unfortunately it's not that simple. Those who chose BBS02 are looking for something that torque sensing cannot offer, like the possibility to arrive at work not sweating, or to overcome some leg disability... but they still don't want to risk their lives in order to have those possibilities 😅 at least, with the 750W version.
of course if someone doesn't need constant assistance, torque sensing bikes and kits are perfect without any need to tweak!
On my BBS02b I changed the 'throttle handle' thumb throttle from current to speed and it made it much smoother and linear. Before when set to speed it was just like an on/off switch. thanks for the video 👌
Thanks to you John! I'll try that 😉
Hi- you say you changed it "from current TO speed", but then say "Before when set to speed"... this contradictory. What setting did you end up using? Thanks.
@@garyfisk370 Hello Gary. Yes i got that wrong didnt I. My BBS02 is now set to speed and that seems to give the smoothest throttle. If you try 'speed' under no load (with the rear wheel lifted of the ground) then the thumb throttle is really smooth and variable, incremental, progressive, whatever the word is, but under load as in normal riding this is less obvious but still seems smoother than using 'current'. My advice is try both. Conversely on my BBSHD I have it set to current as that seems to give the better response in actual riding. (BBSHD with the rear wheel lifted under no load and using 'speed' then the throttle seems really controllable from barely spinning to full speed as you move the thumb throttle but this doesnt translate to actual riding when the motor is under load). So try both.
Hey man. Before I bought my BBS 02 motor, I watched some of your videos. They really helped in the decision and I absolutely love the Bafang motor. And yeah I agree, the power/kick on lower settings is a bit too much for a city rider like me. Gonna get that USB cable and do some tweaking. Thanks mate
Sure Fahad! Thanks to you for your interest
Yeah, factory default setting is too strong. I worked on my settings few times and now im very satisfied. It reacts the way i wanted. But truth is, torqe sensor still wins :) but i made 10000km on my bbs02 350W and it still works like first day.
Great video Luke - exactly what I was looking for. I just converted to a Bfang mid 250w which run just fine from level 1-9. Upon converting another bike to 500w - the power seemed excessive even at low levels, and my concern is now understanding how to respect the CH ebike limits. Look forward to watching your other video see what else I need to learn. E vedo che hai tovato la bellisima zona del lago di St. Sulpice!
The great advantage of the BBS02 is the extent to which its characteristics can be adjusted to meet the needs of the rider. Changing power levels and rates has a dramatic effect on the how the bike reacts to rider inputs. I also use an an Eggrider that offers the ability to not only have 2 separate provides but also to make changes essentially anywhere. I found that the process of fine tuning required many changes and took a good deal of experimenting on the road - ideal with the Eggrider. However you do it, you will not get the full benefit of the BBS02 without controller tuning...
I hope the Eggrider is improved over the original. Mine stopped working when the bluetooth dongle developed a short (no Eggrider display back then). I have since the original version started using a phone app called Speeed.
Bottom line is you have to fiddle with stock settings to get your perfect ride, no matter how you do it.
There's no any advantage.it'sjust crap stock controller that you tinkering with
Very helpful video, thanks! One question, though, I see here, and in other BBSTool videos for the Bafang 750w mid drive motors, the 100% current limit is at around 24A, with 48v battery, this is just over 1100W... no issue with this!? Why not reduce the limit to 16A and protect the motor?
Needs a electronic level sensor so amperage could adjust amperage for hills.
Thanks for this one Luke. I too have a Bafang 750w 48v kit installed on my Tern link D8 folder. So instead of 10%, 20, 35, 50 and so on from level 1. I have to reprogram it again to my specific riding preference and battery management range to 8%, 14, 20, 30, 45, 60, 75, 85, and 98 respectively. Great vid man.
I have a setting on mine and it's just a simple lectric that has the initial torque setting. Of course I turned mine up not down but it doesn't have the gear reduction as yours does.
do it x 1.44 for each value. I have mine limited to 18 A
And it goes like this
1 - 1.8A 100%speed
2 - 2.52A 100%
3 - 3.6A 100% and so on
So times 1.8A x 1.44 as as starting value (10% of the total 18Amps) and go up.
Ending assist level 9 with 18A 100% speed or lower speed percentage if you need so.
Bella Luke, innanzitutto ti ho seguito dalle tue prime pubblicazioni e sono contento del progresso che stai facendo nelle visualizzazioni ed iscrizioni, ben per te :) Ho voluto provare la tua configurazione ed effettivamente funziona mooolto meglio rispetto alla default config, diciamo che l'assistenza è molto più graduale e naturale. Toglimi un dubbio: se io imposto a 5 livelli di pedalata mi confermi che il motore fa riferimento ai livelli 0-1-3-5-7-9? Poi, credi sia il caso di aprire la calottina (dalla parte destra del motore) per pulire e re-ingrassare la parte meccanica, quella delle delle ghiere, per intenderci? credi sia safe provare a farlo o rischio qualcosa? Tu l'hai mai fatto? Grazie di averci portato la tua esperienza, seguirò eventuali aggiornamenti 🙂
Bella Luca, grazie per la fiducia nel canale 🫶
intanto ti confermo i livelli da 1 a 5 come li hai elencati! quanto a reingrassare il motore, è una buona pratica di manutenzione. io al momento non ci ho ancora provato, conto di farlo verso i 5000km.
se cerchi ci saranno sicuramente dei video a riguardo, ma in effetti prendo spunto dalla domanda per un video futuro
grazie del feedback! 🤜🤛
I have installed 2 Bafang 750 mid drive kits now and neither of them have EVER made my bike wheelie or go out of control. Recently I detuned both bikes to more gradually deliver power on the onset of peddling. Mostly to lessen the feel of the assist. But, not for the over dramatized wheelie or out of control thing. Not even on setting 9 will they do wheelies. You have the 42 tooth front sprocket? If you do, and this is probably why you are doing wheelies. Most riders should be using 52t front sprockets as the smaller sprockets are for mountain bike set-ups.
The best thing I bought was the eggridder V2 display for my bafang mid-drive motors I can change all my settings from my phone even when I'm out on a ride it's a lot better than the cable to configure your controller settings 😀
hey man! I heard about it, it seems like a super cool thing!
maybe not the one for me specifically: I'm more like "study it at home and then just drive the result", but it's definitely better if you want to test things "live", like you say 💪
@@LukeLorusso I agree when I'm out I don't mess around with the settings like you I just study it at home then apply my changes for my next ride infact I've not changed them since

Yeah I use the eggrider v2 it's very handy to have, saves having the cable with you as well.
Hello Luke! Great video mate, I'm going to buy a bafang 750w with a 48V 20ah battery, it will be a good one? I just need help with the screen, I saw the 500c display where we have the 9 levels assists. But I really like a small one called sw102, with 5 levels. To follow you, the 9 levels converted to 5 will be like "1-3-5-7-9"? Thanks a lot for sharing how to update the motor
Luke, have you tried looking at the eggrider? I don't have access to a computer, only an Android tablet, phone. I just purchased a 759 w bbso02, and eggrider and would love to apply your downgrade.
I too purchased the Eggrider and like the fact that you can change settings on the road anywhere anytime. Not only that but you can have two different setups at the push of a button.
I use 56v 14s 2p battery packs on my 48v Bafang BBS02 750W. I've even used 60v packs but it can shut down for Error #07 overvoltage on the display if anything going over 61.5v as it will flag a 07 error. After the initial 2018 Bafang purchase and 1500 miles as of Oct. 2023, I may have burned out one of the MOSFETs (error code #12) current sensor abnormality. I don't know for sure if it was overvoltage that caused it but I might downsize the wattage next time just to keep it safer on the 56v batteries.
You are one of those people who will have a burnt down house and a post on Reddit blaming the battery manufacturer.
i have mine set as 100% for allPas 1-9 in the speed section. this way i have max power on the throttle if i need it in a pinch. Any thoughts Luke ? BTW great to see videos on fine tuning, well done.
Under the throttle section of the programing app, you can change the pedal assist setting from "given by display command" to 9 or whatever level you prefer to lock your throttle level at. This way your throttle is always set to 9 (100%) without affecting any of the peddle assist %.
Hi Luke, great video! Thank you! My wife's bike is the BBS01 250W 48V with a small display with only 0-5 PAS (BNS136) do I only need to program the first 5 levels and leave 6-9 empty? Thank you for any insights
Good video, thanks for posting.
Is there a way to speed up the PAS response?
I have gone through all of the settings and now my throttle works much smoother and the PAS levels are just what I want. However, the Pedal Assist comes on way too slowly, only after 2 complete revolutions of the pedals. Is there a setting that controls this? Thank you!
I followed another guys settings so that power was 5, 10, 15% etc increases - with throttle tied into pedal assist 8 (80%) for a quick burst if you need it
I see... yeah mine it's a simple suggestion: everyone should personalize the settings based on their needs, there's no right or wrong, just endless permutations of values 😅
I had a need and solved it this way, but anyone should tune it differently for different needs: I just wanted to show how 😉
I did something similar to my sabvoton build. but what i did change was that i nerfed my phase amps a lot rather than battery amps. before i had great acceleration and could go up any hill but my controller was hammering my battery at any speeds. after i lowered phase amps it uses a lot less battery at lower speeds but i still have decent mid t high end power and speed. it moves pretty slowly from a standstill or going uphill at low speeds but then thats countered by pedalling through it. I almost doubled my range on my route to work (its an offroad footpath with about 0.5 miles of road at the end)
If you are changing the amps, you must also be changing the watts.
Ciao Luke. Ho visto tutti i video che hai pubblicato e sono tutti molto interessanti, ti fanno venire la voglia di fare esperimenti e costruire un'ebike. Infatti sto valutando se fare l'upgrade ad una vecchia mtb che ho ferma e sono intrigato dal kit Tongsheng. La bici ha 3 corone davanti e 7 rapporti dietro e facendo l'upgrade la diventerebbe monocorona, non mi è chiaro quanti denti sarebbe meglio avere. Inoltre ho visto che sulla tua bici con il kit Tongsheng sei riuscito a mantenere due corone davanti. Penso che avendo pochi rapporti dietro riuscire a mantenere una corona in più davanti renda la bici versatile, l'obbiettivo sarebbe poi quello di usarla per fare qualche giro su sterrato in montagna in salita. Hai qualche suggerimento? Grazie!
ciao Filippo, butto qui qualche pensiero sperando che siano utili.
Si, ho messo la doppia corona (44 e 48) ma quella grande per il motore da 500W era troppo alta, il motore faceva fatica, quindi l'ho rimossa e ho mantenuto quella da 44.
In generale per un motore da 500W 44T è "ok", dovresti scendere di dentatura se vuoi attaccare salire molto ripide, ma più di 44 per esperienza personale non serve. Con il Bafang sarebbe un'altra storia, esendo a cadenza: puoi arrivare a velocità più alte con una dentatura più ampia...meglio però disporre di 750w in tal caso.
anche io ho 7 rapporti sul tongsheng e credo siano sufficienti!
I cut my 350 watt hub to 7 amps & it goes to 15 amps.
I never thought I would us 0-9 settings, but I tried it & now use it all the time.
I'm pretty happy getting up to 12 mph. I like using the bike to aid fitness. The temptation is to overdue it & suffer injury.
Man... someone needs to make a tool like this for the newer bafang motors. The official besst tool is really confusing
I believe you are right and wrong at the same time.
You seem technical so to share...
Air drag grows at the square of velocity
Power level required grows at the 'cube of velocity"
Translation:
You want an exponential power delivery curve.
You are right in that the factory programming of your BBS02 was way off for good power modulation at low speed. True
But, I am a BBSHD 52V 19.2 amp-hr owner on two bikes with 1700 watt maximum.
58.8v (battery full charge) X 30 amp = 1700 watts
Yes, I rarely use the 1700 watts but I do 'sometimes' for riding 30mph+ for short periods out on fast roads.
Using the Bafang Configuration tool...
I start with very incremental lower power settings for over 1/2 of my power settings...I use 5 power setting. Then I ramp up to 70% power for power setting 4 and 100% power at power setting 5.
95% of my riding is in power settings 0-3. I program power setting zero to apply 10 percent of power. I do like to race on occasion. I also have had elite road cyclists...no motor hold my wheel at 30 mph so I like to have power to ride fast.
What most users will appreciate is 'granularity' at lower power settings to fine tune power delivery at speeds from say 0-24mph or so. Above that because power required is the cube of velocity, you want exponentially more power to propel the bike faster. So power delivery, again in my opinion, should be non-linear, not linear.
So you are correct in more gradation at lower speeds but as you get into higher power assist, this should not be linear 'in my opinion'. More of your power settings should be smaller spaced at lower assist levels with a much bigger jump at highest power settings.
My opinion. Big power is a good thing on an ebike 'when needed'. But also as your video suggests, so it granularity of power settings at lower speeds to make the bike more docile and natural as you say at speeds that are most commonly ridden.
A very good video and wanted to share my opinion only. Completely agree the Bafang Configuration Tool should be used to reprogram the Bafang controller. I also like having my throttle be 100% available in each power setting....and slower pedal assist ramp up as you mentioned.
Cheers from America where speed is scrutinized less than Europe where you have a 15mph speed limit on ebikes. Police in America could really care less about ebike power if we ride respectfully which I always do. I ride to the speed of my surroundings and don't abuse the power I have.
PS and what fabio said below. 100% speed for each power assist level. Reason is, let the power available limit speed and not put an artificial ceiling on speed and limit power assist.
I will change my settings on speed limit because I do feel like I hit a wall if I get to the top speed of each level,I had not thought of this thanks
@LukeLorusso what do you think
Hi thanks for your input! I have a question about only using 5 levels of PAS, when programing do you not put any values in for 6-9? So only 0-5 have data? Our display only has the 0-5 PAS option (BN136) so I'm wanting to work with that. Thanks again
I would basically want each assistance level to be a certain amount of power instead of cutting off at a certain speed. Well I got to get mine installed before I can start playing with the settings.
I also wanted this. And so I did.
Change the Speed Limit to the maximum level you can comfortably pedal. Mine is 65% (about 85-90rpm).
Then just change to a linear current increase for each PAS mode (except for 9 which is 100% power at 100% rpm).
This way, you can pedal as fast as you'd like (or slow) and adjust the PAS to get more or less assistance.
I am however considering doing a logarithmic power curve instead of a linear one, mostly to give me more choice for lower power levels. Over about 500W you won't really add anything, so any PAS level above this is pretty much redundant.
I'm thinking something like.
Power in watts.
75W
130W
200W
280W
350W
500W
750W
Max.
Can you post a link to the excel file? This was extremely helpful.
Thankyou
Hey, I just added it in the description 😊
i droped mine from 25A to 15 A and goes fenomenal to the moment , and also im using the App Speeed from bafang , on my phone , with this App dont needs a laptop to do changes
great post .. very useful info !!
I did the same with the assist, then gave the throttle 100% Now that i'm used to it i wish California would allow the 1000 hd on the street, especially when dealing with traffic and long distance commutes.. i did pick up a 52v 25ah battery and can hit 42mph full throttle while peddling as fast as possessable, but i wish i could hold 35+ mph with out having to peddle my ass off !!!
Do you think I can adjust the Limit Speed to 25kmh just for the throttle in case of police contrôl 😂. And go more with Pedal assist ?
Questo canale è l'orgoglio barese Ahaha ❤
Thanks for sharing valuable information. Do you ever have to worry about the legality of 750w?
I'm more worried about accidents and insurance claims than occasional police checks. Here in Austria also the max power is limited to 600w and the continuous power to 250w. I'm not even sure if limiting the power and speed in the controller would make it legal. I'm going to receive my 750w kit soon and don't care much anyway.
Hey thanks for your question!
Where I live it's possible to have powerful ebikes (mopeds, up to a certain W limit) if you comply with the rules: having a licence plate, driving licence, insurance and wear a certified helmet.
Unfortunately, if a custom 750W build isn't legal in some places, downgrading it won't make it suddently legal...
I believe those motors are made for cargo bikes, and that's why they are so powerful. If someone really wants to use one of them for personal transportation, here I show some options to make it "closer" to a less powerful kit in terms of behaviour and personal safety... but not in terms of the law.
@@LukeLorusso
Many thanks for your answer! I understand you have to keep it legally "correct" here.
I'm going to limit the speed and power and use it as a bicycle (not a freaking moped) responsibly regardless of idiotic laws. Where I live hills are too steep for everyday commute with a 250w bike.
After all, we are doing everyone a favor by not driving cars, and laws are supposed to support the idea!
Stay safe
@@persiathiest1963 if all RUclips user were like you man, this would have been a better place ✌️ good luck with your settings
@@LukeLorusso Thanks! I appreciate your kind words.
@@persiathiest1963 Stay active and vocal to change those idiotic laws!
Do you get a ticket if you don't use your brakes going down a hill? 🤦
There's absolutely no reason an adult can't have a personal e bike any damn way they want and follow common sense traffic laws. (Power and control!) Let's never forget what these idiots did to us during the "pandemic"
The legal maximum motor watts in my state is LESS THAN 750, so 750 is technically illegal. Does your method enable you to make your motor 749 Watts & legal?
some people (I've seen this a lot) set the speed limit for 1 speed to 100% to pedal only on it
Yeah, it makes sense if you don't want to pedal much
hi thanks for your mid motors video series , they helped me a lot . want to ask if I order a BBS02b 500W . can it be upgraded the same way to 750W ? Do both have the same hardware ?
hey! that's not something you could do
first of all, 500W has 2 variants: 36V and 48V, while the 750W only exists in the 48V variant.
if you take the two 48V versions, what's different is not the motor itself but the controller, which ideally you could replace, but I can't see why not buying the 750W directly instead of messing with the 500W one
Oh i was not aware that they have different controllers, i thought it can be reprogammed without hw change . yes i am planning to buy the 48v version.
I actually assumed 500w will be enough for me at the moment , but would like to have the possibilty of having more power when needed.
Does actually the 750w act after downgrading the same like original 500w or 350w motor or is there still differerences ?
@@ahmed4052 you can surely downgrade it, now I'm not sure if there's an actual config to make it behave "exactly" like a 500W or 350W, but with these setting I'm showing in the video, at lower levels it feels innocuous :)
@@LukeLorusso as far as i understood you have/had both kits 750w and 500w ,right?
Did u notice any difference in power or range?
I mean the 750w after downgrading and the 500w kit
Im getting a 1000w kit
Does somebody know What it means if I get a blue light
Would you have a recommendation for settings with the speed limit of 25km/u ?
We need to know how to DO wheelies and go FASTER!
🤣🤣🤣 try the opposite of what I did, it might work! ...just kidding, don't 😆
Hello my friend, i'm John from Portugal, i like tour vídeo, and i need to ask if is possible send the link for the program download to so i can do the same in my bafang bbs02b 750W
Thanks

Hi, could the low cut-off voltage be set lower than 48V-38V in this engine? 13S Samsunf up to 32V would be ok.
Hi Luke, thanks for sharing!
If you have an Android phone, take a look at "Speeed" by Marcin Kompa. Yes, spelled with three "E"s. I've used it for a couple of months on a BBS02B and a BBSHD.
It does everything the Windows app can do, only you can do it anywhere. I think it's really awesome.
I'm not affiliated with Bafang, Mr. Kompa or Android, in case you are wondering.
Hey Herald! Thanks for sharing.
I actually tried that app and surprisingly, even if I changed just a couple of values, that app also changed parameters that I didn't intend to change... I don't remember which one but that made me think. I know it cause I read the values with my PC after flashing from the app.
I'll stay with the PC method, also cause I don't change settings that much, but it's surely a good on-the-go alternative :)
@@LukeLorusso That happened to me, as well. In my case, my mistake was not using the "READ ALL" button on the "Home" tab before doing any editing. It wrote the apps default values, which I had edited instead of the controller values. Aside from this incident, I never had any trouble. Usability isn't perfect, to be sure, but I think you have to do that on the Windows app as well. Now, I usually edit the values in the *.el files or load the *.el files and edit them in the app before flashing, so I might have missed unreliable reading from controller incidents. I also only use "WRITE ALL" from the "home" tab, not the "write" buttons from the detail screens, because I am uncertain if they write everything or just the values from the specific tab.
@@heraldreichel1971 wow man that's really useful!
I'll try this out 👍 thank you!
Way too much math! I just did the adjusments in a fashion that seemed more linear then used the "SPEEED" app (on my phone) to adjust programming on the fly until I got it right for me. My 02 is set up to be "class 1" and I have a tiny 6AH battery so 18 amps was more than enough to maintain 20 mph on flats and still climb hills with ease plus I get better range from my tiny battery. An added benefit is that at 18 amps the 02 is virtually bullet proof reliable.
Can I use the exact numbers you have here for my bbshd with a bac855?
I guess yes, absolutely!
consider that these are % values, so on an HD 1KW they will translate to almost a 25% boost on levels compared to the 02 750W, but they'll sure make your experience way better overall ✌️
...not sure about the BAC855 thing btw 🤔 can you still use the programming tool with it?
Ciao, scusami ma se uno vuole depotenziare ad esempio un 350w via software e portarlo a 250w, nel caso dovessero sequestrare il mezzo e per fare delle verifiche, si accorgerebbero che originariamente era un 350w, oppure pensano che sia un vero 250w? Grazie
That Computer bafang configuration tool is way complicated.. I used my programming USB cable / w/adapter DataCable to usbC / Then downloaded an Android APP called "SPEEED" on my phone.. I can do everything on the fly with this simple Android APP on my phone..
You can adopt this profile using the Speed app too if you like: you just need to copy the values over 😊
Is this the old bbso2b or the newer one? The newer are the CAN bus right and they cannot be customised like this?
that's the BBS02B, which apparently will survive alongside the newer one.
BTW some early experiments (I didn't test it) are showing that replacing the new controller with the old one allows the customizations to be done on the newer one two
Luke pensi che bbo2 750 va bene per un rock rider 520 explorer dechatlon oppure. Dovrei prendere quello nuovo nuovo 625 1000w. Perché ho molte salite per arrivare a casa. Grazie
Ciao! non ho mai provato il nuovo 625 quindi non posso dirti in merito...
ma quello che posso certamente dirti è che 1000w è mostruosamente troppo...
a meno che non guidi una bici cargo, o pesi più di 150kg.
I rapporti sono spesso più importanti dei W! un rapporto largo diretto e stretto avanti fa fare salite incredibili anche a 500W
Il consiglio che posso darti è: risparmia sul motore e spendi in batteria! almeno 48V 17Ah
Not a downgrade more of an optimization.
I have the 500w and I can say that it does feel too aggressive. These settings should have been in the screen itself. We shouldn't have to hack it.
Thank you!
My battery lasts for 100km... but the throttle is so aggressive from the start
that I cant use pedals in combo or tell the difference in assist levels😅 (why do they even exist in face of custom software or instead of factory linear/optimally tuned throttle???).
The speed limiter isnt power efficient. If 10% current can give you 20km but you limit it to 10km your wasting 50% power.
my motor always heat up after 4hours of usage or 1hr during sunny days. If you set the controller amp limit from 25 to 18 or 20? Will it lessen the heat issue?
Current creates heat. So yes
can i just plug a 48v 19.2ah battery on my 36v 500watts motor? thanks
I don't think so man 😅
This program from Bafang is in Windows only? I too do not want all the power the motor has. I just want some help on hills and head winds. Thanks for the video. I gave it a thumbs up too.
hey! yes this one is for Windows only. the other possibility is to use an Android app (which is not equivalent) that allows you to read an flash settings with an OTG adapter and the same USB flash cable: play.google.com/store/apps/details?id=com.mkopa.speeed
remember to read the default settings and save them before starting playing with the app 👍
@@LukeLorusso Android runs on Linux, so the computer program could too if they wanted it. Probably started out as a Linux program and was ported to windows.
@@bigwheelsturning Android is a Linux-based OS, but Android apps are built to run on ART ( source.android.com/docs/core/runtime ): they're not built for Linux.
If you find a way to run them on a compatibility layer on a Linux distro, that's a different story, but I won't bet 100% that would work.

I have the 1000W . The bike feels very jerky and cheap
They had to use a torque sensor to adjust power to your needs. But this cheap product lacks it.😢
j'ai un bafang 500 watts et c'est largement suffisant pour mes 90 kgs
au début je pensais parement, chez moi dans le sud d'Italie.
Ici en Suisse par contre... il y a quasiment toujours des montées compliquées aussi en marchant !
du coup honnêtement, pour ce cas las, je trouve que le 750W aide beaucoup mieux
No speed limit pedal. And 10 20 30 ect amp assist 😏
I like my bafang 750 just as it is.. I use 3 assist levels... not 9. You need to click.all the time.. like playing playstation. I use assists 2 and 3... never 1. Its too weak
Mine works fine as they are 1-9…

Kind of silly to ride an illegal motor (most places) and downgrade to what a 250W would give you. I fitted a 250W kit for mtb trail it does the job perfectly. And if i get in zn accident on the road and they check my motor i won't have legal issues. Riding with 3 times the power that's legal on the road is too many liabilities to me
as I said in various videos, not everywhere it's illegal to drive a motor higher than 250W nominal. hence, there might be a LOT of people (say in north america) who can ride 750W motors and still feel unsafe with the stock configuration.
I'm happy about your 250W choice, I also believe it does the job (in flat areas), but those videos are meant for international viewers, with different legislations. please, always mind this
Cry baby, I have the 1000 watt and love it. If you're geared very high I can see the torque being crazy but 46 tooth in front and 26 in back isn't wheelie ville. If you want a torque sensing get the m365 mid drive. Geesh
I don't want ever ghost pedaling, I want to pedal all the time so mostly would keep in level 1....I want the battery to last for the longest mile.
I can't believe parents allowed two young girls that never rode an ebike before and got one girl killed in CA!!!!
What gears do you have in the back??? I am going to put the 12 gear cassette...
CUT THE GREY PAS WIRE!!! PAS IS USELESS.... Make your bike a throttle only bike! Then those PAS settings will be the power settings of the throttle!! You ride your bike like a bike and add power when and where you need it! I've built over 20 bikes and the ones I set up like this for people they couldn't belive how much they loved thier bikes again.
Can you provide a link to show me where in the programing software that I can disable the PAS? If so I will test a drive without the grey PAS wire cut and see if it behaves the same as my set up.

Where is the logic here? Instead of buying a 750W motor, you had to buy a 250W one and not mess with it. You paid for a 750W motor that you don't use all of. It does not make sense
the logic is all there, you might want to re-watch the content paying a bit more attention to what it's said. those mods don't transform the kit into a 250w motor, and all the power of the motor is still there. what changes is its distribution throughout the levels.
maybe the follow up will clarify even further: ruclips.net/video/HEGihE0BZEo/видео.html
Can I do this to my 1000w power BBSHD? I agree it starts to fast thank you.
Hey, yes you can definitely do it on the HD too :)
