exatamente o que eu queria saber... usar com o câmbio da bike de forma correta aumenta muito o desempenho do motor ... sempre vi vídeos de pessoas testando esse mid drive mas sem usarem as marchas da bike .. video perfeito util e excelente uso do câmbio
Cool video loving the scenery mate, 61khm I had about the same maxed out down hill too, when I'm on a flat road it usually does around 30mph in my experience, that's a nice bike too, plenty of space for the battery 🔋 have a good day mate 👍
Nice bike build have you tried the eggridder V2 display it's great you can change a your settings from you phone I've changed mine in the BBSO2 and now I have full throttle no matter wot assist level I'm in and changed some of the settings in the assist to suit my riding style I olso bought the 36T chain ring and your bike runs very well I'm impressed 👍🏾💯
Is any bike, or its parts built for those speeds? Is any seller explaining all the details and risks of gear change at those torques? Are there any realistic data on how much these motors output and consume at different settings and circumstances ( i live in a very steep hill area with bears that i need to avoid fast so its a matter of life and death and available data vary insanely)
I got a 750w mid drive motor running off a 48v 26ah battery I be getting 32mph here in nyc streets pretty strong setup last a good 5-6hrs full speed everywhere i go But you have a nice setup yourself ⚡️🤘🏽💯
@@Hema115 nah not too much but definitely to be fair I was riding for about 5/6hrs before a charge some of my bros on my team got 60ah 55ah they last damn near three days no charge up
Bike speed on a Mid-drive is all Math ... Do a spreadsheet where you convert One Pedal revolution x Gear Ratio (33 tooth chaining/11 sprocket rear) x Circumference of wheel (27.5" x 3.14) = 259 inches travelled per crank. (21.58 ft) Get max cadence speed of 95 RPM x 259" /12"/ft/ 5280 ft/mile x 60 min/hr = 23 MPH. MPH is for Americans. For KPH multiply by 1.609 = 37 KPH. You do spreadsheet so you can change gear sprockets numbers and wheel diameters. I bet when you're in first gear (42 tooth sprocket) you can pop a Wheelie when you crank the throttle. You could try a bigger 42 tooth chainring for more top end speed on a flat, but that creates load and heat on motor. Watch your wattage, Get above 1200 watts for a long time may burn out controller. Stock BBSO2 max rpm on throttle is @ 95. Ebay and Ali Express sells 42 tooth chainring with OFFSET @ $40 US. Lot cheaper than Lekkie Bling ring. Go with no Offset, you get chain alignment problems - 1st gear, chain slips off. Having a Left hand mirror is Smart. If there's no cars behind you, take command of the road if there's too much debris on the sides. Highly recommend a good bike bell for passing pedestrians and other bikes. Try not to go too fast, you'll scare them and give ebikes a bad reputation. Safe rides and beware of sunken manhole covers, catch the rim with a skinny tire = quick 90 degree turn = Off and Ouch.
And what about the weigh of the rider and the weigh of the bike and how air dynamic your bike is and the person on the bike and what psi for your tires along with wind speed
Very neat build. I have bbs02 with a 13ah battery. Battery runs out pretty quick if i use throttle only. With pedal assist I'll get 35-40 miles. Throttle only maybe about 7 or 8! I have the bafang 52t chainring with 7 speed cassette. chain comes off a lot now since i changed from 44t to the 52t.
I have the same setup with the same problem, chainline slightly off. I used the old front mech cage as a chain guide, fitted as close to the chainring as possible, the chain has not come off since.
Itu dikarenakan ukuran crank yang besar,semakin besar crank depan maka semakin berat dan semakin banyak daya baterai yang dikeluarkan ,torsi pun melemah
Yup me too same problem this was my first build got it from JNO complete basic kit $852 BBSO2 750w. I did upgrade the cog from 11-34T to an 11-46T with a new chain 8 speed. A stock 44T chainring. A beast at climbing! I had the option for a bigger battery but, this was my first build on a Trek 4500 26". The battery is 48v-10ah MJ1 cells work fine for very short distances then die. I should have gotten the largest amps 48v or 52v.
Dumb question but what is the green button left side for? I see you press it hold it down when /after slowing down ? Is this Pedal Assist? And do you increase or decrease the assist level when at low speeds?
@@mariostomas Is the Kill Switch a Option You Installed? Bafang has the Brake Sensor & Shift Sensor to Kill the motor when used. Also, do you shift gears while using the throttle only, or is that bad for the drive train & derailleur ?
@@connicrow9463 to shift gears without damaging the drive train you have to stop the motor for a split of second. This you can be done with many ways. By stop pulling the throttle for a second , with a kill switch connected to brake sensor, by pressing the brakes (connected to brake sensors) . You can choose your way that fits to your habits. Generally the kill switch or the brake sensors are not necessary. You can change gears perfectly, only with the gear sensor and the use of throttle properly .
@@mariostomas I find it interesting that you as an experienced rider feel Brake Sensors aren't "generally" needed, and Gear Shift Sensors are better to protect the drive-train. Because in the Bafang kit Brake Sensors are Always Included (a Safety Standard for E-Bikes?) -- and Shift Sensors an optional buy. Most Gas Scooters / Motocycles do not have Brake Sensors; if there's a Gear Clutch it's operated w/ the left bar lever to temporarily disconnect the transmission from the motor (sort of like an E-Bike's Gear Shifter Sensor). Last question: Does your bike in the video have a Gear Shift Sensor? And are you thinking to remove the Brake Sensor + Kill Switch (to reduce bar clutter & less wiring?). Or this isn't possible as the Controller & Display will malfunction?
I got the same Bafang BBS02 750 w 48v-10ah battery with 44 T cog pushing a Trek 4500 26". I should have gotten the 52v-25ah battery the 48 v doesn't last long on throttle maybe 8 miles flat. How can I upgrade battery range cheap?
You pretty much have 2 options, 3 if it doesn't matter: * First is that you purchase old used 18650 batteries, a spot welder, nickel strips and a BMS (Battery Monitor Sensor) and DIY it. - Makes for a cheap option while you may not get top notch capacity, many used batteries still have a lot of charges left in them as many are changed due to bad individual cells where many are still good. Some companies also uses programmed life span so that users have to have these replaced, so you can earn big money here! * Second is buying brand new cells and DIY it - Best way to assure full capacity, and quality as you get what you pay for. Not much to say other than it's the best option since you can chose your own capacity, just make sure they can output a lot of current continously (8-10A is a good number). * Third is buying any cells and DIY it - This is not a good option since the capacity and voltage may vary between cells and can give out before it's supposed to, both power wise and life expectancy wise. This would typically be something you see in in Indian RUclips videos where they aquire laptop batteries en mass and just schmush them together so that they have something to show in their videos (and probably not working for very long, off-camera). These are not cheap, but compared to buying assembled battery packs, it cheaper. Especially for when it comes to what I describe next as pre-assembled aren't made with extreme Ah since they're made to fit battery boxes of a certain size and look; As for the number of cells: That's up to you to decide. 13S (48V) or 14S (52V) (Number of cells in series), and anything from 4P (Cells in parallel) to whatever you want & can mount without it weighing down the bike of it's center of gravity. You could theoretically fill up the whole inner triangle with batteries but it would be very very heavy and susceptible to impacts/punctures unless well padded, not to mention the obvious weight, but you'd have a pretty decent battery time and a very sorry wallet. Also keep in mind the number of cells in parallel should also be taken into account when selecting a charger. You need to see the datasheets for the batteries in order to select the proper one. Most cells have a maximum of up to 2000 mA, or 2A for short, and this can be multiplied with the number of cells in parallel but never exceed this since it can make the batteries explode (Note that the BMS should prevent this, but don't take any chances!), so if you're using 15 or 20 in parallell, you might want to consider getting a 10A charger since 2A (which is usually shipped with some e-bike kits) takes about an hour to fully charge, so that divided by xx cells = long time. But, always check on the datasheet and just calculate. Just a few options to your question. And yes, by DIYing you can save a hefty sum of money. Hundreds of Dollars if nothing else.
Hello. I m planning to install the bafang 750w with 20ah battery. Yours is very impressive. The 36t in front is ok ? I have a 32 but i do not know witch one to put?
Lookup "High Voltage" channel, checkout his BBSHD on a Specialized Fat Bike - Boss bike, goes 42 MPH due to ASI BAC 855 controller. Motor RPM hits 8K easy. Understand why they stay with First gear sprocket to keep motor from overheating.
φιλε μου καλησπερα ,μπραβο σου για το βιντεο που εχεις ανεβασει, να δουν ορισμενοι τελικα τι δυναμη εχει το μοτερ, με την μπαταρια που εχεις τι αποσταση μπορεις να διανυσεις?
Bergab kannst auch 70kmh erreichen ohne EMotor, er hat 61kmh Bergab ohne unterstützung geschafft, in einer Szene geht er vom Gashebel, wird aber schneller und kommt trotzdem auf 61kmh
Nice build, the only criticism I have is that the motor is hanging low. When turned up towards the frame the bafang logo will be level and give you more ground clearance
Shoulda gone with the BBSHD. 750W stamped but can be software unlocked to 1500W or swap the controller with the Ludicrous controller to make it 3000W. much better upgrade path. Love my BBSHD/ Ludi combo. Whenever I get stopped they just look at the 750W stamped on the motor and I explain it goes so fast due to an 8 spd IGH.
You know, a comma goes a long way, and could be the difference between life & death: "We're going to eat grandpa", or "We're going to eat, grandpa". If not applicable, try punctuation and initial capital lettering to follow. If nothing else, it makes a sentence understandable instantaneously without having to read it several times.
If you use pedaling the battery 48v 17,5A is enough , if you use the throttle only go for the maximum capacity that you can afford (25Ampere and more).
the chainring is 36 . With this you can climb very stip uphill roads with the help of the motor. Smaller than 32 is not needed in my opinion. Now i am using 38 which fits perfect in my needs.
@@mariostomasdid this have a big effect on the range you'd get out of 1 battery? F.e. the 44t will achieve higher speeds, but might drain it faster (not when cruising but when accelerating) right? Lemme know, cuz I'll get a 44t in my kit, not sure if I want a bigger or smaller one, or of this one is OK (everything is mostly flat there)
One thing I found interesting was my bike doesn't stop like a car at that speed. An emergency stop at 30 plus MPH may not go as well as you'd expect. The bike may stop but the body may not. LOL
and watch your battery get hammered! I have a 52v 24ah EM3ev Panasonic battery and after 20 miles of 20-25mph riding with steep hills it's used half the battery and it's getting weak due to low voltage at that point. Still tons of watts left at 50% but the voltage has dropped to say 50v instead of 58 and it's not as torquey.
The battery capacity is 17,5Ah. only throttle i can go easily 30klm. Throttle + pedaling i managed 50klm with 50% remaining battery. i supposed i can reach 80 klm and more only pedaling.
@@mariostomas with 750w bafang and 17,5 Ah battery on my trekking bike i can go 120 km on hilly road. My max speed on nice and flat road was 51 kmh throttle only.
i use both , automatic gear shift sensor plus manual (green button) . With this way i achieve the perfect shifting up and down. If you try to change quickly the gears while pedaling, you will realize that the gear sensor alone, is not enough.
@@harveyashworth6285 Green button shuts down motor and he can change gear without fear of motor starting while chain is in middle of shifting (avoiding damage to chain or rear gears). I use only automatic Sensor and if you switch too many gears at once, motor will start before chain is on right gear and sound is not very nice hh
Great bike saw it do 40 mph was that right this must be a 2,500 dollar plus E-bike i couldn't afford this bike I'm on a budget im looking for E-bike but for cheaper prize
▪️ It's better for the motor to do it that way, too. Hitting the throttle from no or low speed isn't something ya wanna be doing that much, if at all. 🟥
Μπράβο φίλε. Πολύ καλό κιτ και σε ωραιο ποδήλατο. Εχω λίγο καιρό που το ψάχνω και εγω, ακριβώς το ίδιο κιτ για το δικό μου. Είχες ποτέ κανα θεμα σε κανα μπλοκο;;
I don’t recommend those tires if ur on a 27.5 inch wheeled bike and use the bike for commuting best I found is the shwalbe moto-x(I may have butchered their company name) I found them to be the best on wet road specially when turning they grip very well and have a very good puncture protection cause on those mountain bike tires those knobs are too hard so when cornering if u happen to go to the knobs at the edge when u get a random puddle or a metal gutter cover u can slip really bad(it happened to me on a busy roundabout) plus the gaps in between the knobs like to gather crap and sometimes sharp objects and get punctured cause those are the soft spots so my recommendation to all the diy ebike makers and riders use moto-x if ur commuting or doing delivery jobs remember it’s better to buy one good tire then replacing the inner tube every 50 miles u do..
@@nolanr1400 they are similar as far as I know I think moto x is just a bit more flexible I think so less rubber but I’ve only had marathon on my Brompton which is smaller so it feels more harder I think
On a flat road i reached 50-52khm on full battery without pedal. The video is going downhill. On the same road, performing another test with 52T chainring, i reached 75km.
Hey mate nice build! did you know you can double click the down gears in one movement and use your thumb to press the up gears instead of pointer finger pulling back? so it's all thumb control and your pointer finger is free to cover the front brake when needed. rapid shifter leavers are the best when used properly🤘👍
What do you mean double shift down gears one movement with only right thumb? In this video the rider is changing gears correctly. To shift lower gears (low speed up hill or starting out) he pushes thumb lever with the right thumb. And to shift to higher gears (going faster) the index finger pulls back the rear lever. And he's letting off the left thumb throttle motor just before any shifting to not damage the drive train.
@@rossg9363 I assume you ride a similar E-Bike w Bafang 750? If so what is the size of your front ring / cassette ? Do you ride mostly w Throttle & no PAS ? Given the good torque power of the motor -- do you ride mostly in certain cassette gear ranges -- say 2 / 4 / 6 / 8 / 10 -- using your "deep double shift" method? And does this double shifting method also work with shifting into the faster gears by pulling further the index trigger ?
@@connicrow9463 i own a bafang bbshd 1000w, same 160nm as the 750w bbs02, i run 40t up the front and 10-36 cassette on the back, i use pedal assist and keep the same Cadence speed and shift gears accordingly jumping even sometimes 3 gears down in one push(3clicks) on hills, you can only change one gear at a time going up gears (pointer finger) for obvious reason being load increases (only 1 click available to). I do use throttle on hills with pedalling to keep the cadence speed up if my cadence drops a bit it gives it a bit more grunt. I hope i answered questions cheers
@@rossg9363 Sounds like you have a need for speed w 1000W and are not riding in a big city w traffic. What kind of bike is it and the wheel size & tire model & width ? Do you ever use the highest 10 cog gear ? Or the lowest 32 ? And when you shift do you stop throttle and peddling in PAS for a split second -- to save the derailleur from premature wear tear?
Ετσι πρέπει να είναι ένα ηλεκτρικό ποδήλατο. Καμία σχέση με τα έτοιμα που πουλάνε. Μετά από ένα χρόνο η μπαταρία , εξακολουθεί να κτυπάει 45-50 χλμ στο ίσιωμα.
I don't understand why you shit gears ? 🤔 This motor is so powerful that you could only use one gear, probably the fastest, instead of shifting constantly 🤔
That woman at 6:47 needs to get her head checked cause it’s stuck in only one position and some education of when crossing the road u need to look both ways depending on which way is the oncoming traffic
Dangerous urban area for such a speed test! This is crazy and stupid imho - not recommended and forbidden! If you want to ride a bike - do it with your feet and yourself! Otherwise buy a motorcycle! its in greece i suppose?
@@mariostomas I do agree, this 750 watt is the best setup. I did see a pedego ebike in denver. It's a top tier commuter bike that have everything your bike has but at $4,000, yikes... It's does come with a 5 year warranty though. Thanks for sharing...

Is there a risk of getting in jail or arrested for modding an ebike to go over that speed?
@@WilTK4 idk, im riding 1100W ebike which is very illegal in my country. You have to be careful and you will be good!!
Tak. Kara śmierci @@WilTK4
Nice build, the only criticism I have is that the motor is hanging low. When turned up towards the frame the bafang logo will be level and give you more ground clearance
Due to the frame of the bike , this is the upper position which the motor can be placed.
The battery position is far too high.
@@MrScaramoosh How is that a bad thing you mean ?
@@greveeenhigher center of gravity, would be my guess.
Good information. I almost bought one of these. Now i know
Shoulda gone with the BBSHD. 750W stamped but can be software unlocked to 1500W or swap the controller with the Ludicrous controller to make it 3000W. much better upgrade path. Love my BBSHD/ Ludi combo. Whenever I get stopped they just look at the 750W stamped on the motor and I explain it goes so fast due to an 8 spd IGH.
shoulda just not written your comment; not a who has a bigger d contest.
The 750w Motor cant handle 3000w
Even at 1500 it wont last on a Hill
Those owners of that dog need to stop that behavior.
Any idea how to check temperature? Mine gets very hot!
search for rc motor temp sensor , you will find something.
Are u riding downhill ? ...seems like that !...36t front....? personally have reach 70 kmh down hill with 46t.
Good day, I want to ask what you use the green button on the left side for 🙏🙏🙏🙏
Kill switch for the motor.
That's what I was thinking about my first e-bike build let me drive looks much cleaner in the gear shifts are satisfying I'm going mid drive.
You know, a comma goes a long way, and could be the difference between life & death:
"We're going to eat grandpa", or "We're going to eat, grandpa".
If not applicable, try punctuation and initial capital lettering to follow.
If nothing else, it makes a sentence understandable instantaneously without having to read it several times.

Я на bafang 1000vt по прямой выжимал 45 км.ч а он по серпантину с горочки я на обычном самокате с горки столько же выжму
Hi my bafang hub motor is 9 speed cassette and my bike is 7 speed cassette now I don't know what to do can you please tell me thank you
just divide 9 with 7, mid drves are pure math
Great video... I've watched enough
Is this setup good for food delivery 🤔
If you use pedaling the battery 48v 17,5A is enough , if you use the throttle only go for the maximum capacity that you can afford (25Ampere and more).
0:17 where did you get the cap on your frame?
it was on the frame from the begging.
Any tips on using a smaller chainring? What size is it? Thanks
the chainring is 36 . With this you can climb very stip uphill roads with the help of the motor. Smaller than 32 is not needed in my opinion. Now i am using 38 which fits perfect in my needs.
i have tested 32 , 36, 38 , 44, 48, 52 . I finalized at 38 if this help's you.
@@mariostomasdid this have a big effect on the range you'd get out of 1 battery?
F.e. the 44t will achieve higher speeds, but might drain it faster (not when cruising but when accelerating) right?
Lemme know, cuz I'll get a 44t in my kit, not sure if I want a bigger or smaller one, or of this one is OK (everything is mostly flat there)
@@tennyboy13 44T is perfect for most of the cases . Go for it.
What kind of range can you get with this set up :)
30khm only throttle, 80-100klm with pedal assist
One thing I found interesting was my bike doesn't stop like a car at that speed. An emergency stop at 30 plus MPH may not go as well as you'd expect. The bike may stop but the body may not. LOL
In this speed test, would you say that you are driving down a hill, that the road is going downhill?
45-50klm on flat road , 62klm downhill , if this is what you ask.
▪️
When biking downhill, is the biker going downhill - or is the hill climbing the biker ?
🟥
lmao@@2NDFLB-CLERK
If you would like to go even faster change your front chainring to a larger one
and watch your battery get hammered! I have a 52v 24ah EM3ev Panasonic battery and after 20 miles of 20-25mph riding with steep hills it's used half the battery and it's getting weak due to low voltage at that point. Still tons of watts left at 50% but the voltage has dropped to say 50v instead of 58 and it's not as torquey.
@@nihilisticsoup2919 what gear are you in
The kit says 50kmh. You can go to 60 without modification?
What is the range on low mid and max speed?
With pedal assist only, 100-120 klm range , with throttle and max speed 25-30 klm range. Using both after 40klm range battery still has 35-40% juice.
What the total weight of the bike before and after installing bafang with battery?
14kg bike weight +10kg motor with battery= 24kg total
@@mariostomas not bad. thanks mate. ❤❤
El sillín está demasiado inclinado hacia abajo. Debe quedar idealmente plano.
what is the battery capacity and max distance you travelled on this bike?
The battery capacity is 17,5Ah. only throttle i can go easily 30klm. Throttle + pedaling i managed 50klm with 50% remaining battery. i supposed i can reach 80 klm and more only pedaling.
@@mariostomas with 750w bafang and 17,5 Ah battery on my trekking bike i can go 120 km on hilly road. My max speed on nice and flat road was 51 kmh throttle only.
Is the green button for cutting off the motor? Where can I buy one?
Yes the button is for cutting the motor . Type in google: bafang bbso2 kill switch
Better use the brake sensor
Is there any reason why you didnt take automatic gear shift sensor instead of manual one? Great video, good luck
i use both , automatic gear shift sensor plus manual (green button) . With this way i achieve the perfect shifting up and down. If you try to change quickly the gears while pedaling, you will realize that the gear sensor alone, is not enough.
Can you explain it differently. What is green button.
@@harveyashworth6285 Green button shuts down motor and he can change gear without fear of motor starting while chain is in middle of shifting (avoiding damage to chain or rear gears).
I use only automatic Sensor and if you switch too many gears at once, motor will start before chain is on right gear and sound is not very nice hh

Apo pou to agorases where did you buy it from
Great bike saw it do 40 mph was that right this must be a 2,500 dollar plus E-bike i couldn't afford this bike I'm on a budget im looking for E-bike but for cheaper prize
DIY is much cheaper. Depending on the bike you get it could be around 1000-1500$
I don't understand why every bafang video the user have to start pedaling and the uses the electric motor, can't you start moving just with the motor?
For faster acceleration.
▪️
It's better for the motor to do it that way, too.
Hitting the throttle from no or low speed isn't something ya wanna be doing that much, if at all.

Hi ! What's your Wheight?

Glad your on it not me
I don’t recommend those tires if ur on a 27.5 inch wheeled bike and use the bike for commuting best I found is the shwalbe moto-x(I may have butchered their company name) I found them to be the best on wet road specially when turning they grip very well and have a very good puncture protection cause on those mountain bike tires those knobs are too hard so when cornering if u happen to go to the knobs at the edge when u get a random puddle or a metal gutter cover u can slip really bad(it happened to me on a busy roundabout) plus the gaps in between the knobs like to gather crap and sometimes sharp objects and get punctured cause those are the soft spots so my recommendation to all the diy ebike makers and riders use moto-x if ur commuting or doing delivery jobs remember it’s better to buy one good tire then replacing the inner tube every 50 miles u do..
I'm about to buy Schwalbe Marathon tires !
What's the difference with the moto X ? Which one is better ?
@@nolanr1400 they are similar as far as I know I think moto x is just a bit more flexible I think so less rubber but I’ve only had marathon on my Brompton which is smaller so it feels more harder I think
I use a thick durable slime tube, never had a flat since
How much torque does?
120Nm
I’m only getting 49k I have a 1000 52 15ah?
Put 30Amper max , play with the settings from the application (usb connected). Search the web for settings, there is a lot of information.

Oh man without pedal assist you reached 62 km with 38 chainring? Is that speed is in flat road?
On a flat road i reached 50-52khm on full battery without pedal. The video is going downhill. On the same road, performing another test with 52T chainring, i reached 75km.

Hey mate nice build! did you know you can double click the down gears in one movement and use your thumb to press the up gears instead of pointer finger pulling back? so it's all thumb control and your pointer finger is free to cover the front brake when needed. rapid shifter leavers are the best when used properly🤘👍
What do you mean double shift down gears one movement with only right thumb? In this video the rider is changing gears correctly. To shift lower gears (low speed up hill or starting out) he pushes thumb lever with the right thumb. And to shift to higher gears (going faster) the index finger pulls back the rear lever. And he's letting off the left thumb throttle motor just before any shifting to not damage the drive train.
@@connicrow9463 deep push the shifter further to get more clicks to get faster gears changes.
@@rossg9363 I assume you ride a similar E-Bike w Bafang 750? If so what is the size of your front ring / cassette ? Do you ride mostly w Throttle & no PAS ? Given the good torque power of the motor -- do you ride mostly in certain cassette gear ranges -- say 2 / 4 / 6 / 8 / 10 -- using your "deep double shift" method? And does this double shifting method also work with shifting into the faster gears by pulling further the index trigger ?
@@connicrow9463 i own a bafang bbshd 1000w, same 160nm as the 750w bbs02, i run 40t up the front and 10-36 cassette on the back, i use pedal assist and keep the same Cadence speed and shift gears accordingly jumping even sometimes 3 gears down in one push(3clicks) on hills, you can only change one gear at a time going up gears (pointer finger) for obvious reason being load increases (only 1 click available to). I do use throttle on hills with pedalling to keep the cadence speed up if my cadence drops a bit it gives it a bit more grunt. I hope i answered questions cheers
@@rossg9363 Sounds like you have a need for speed w 1000W and are not riding in a big city w traffic. What kind of bike is it and the wheel size & tire model & width ? Do you ever use the highest 10 cog gear ? Or the lowest 32 ? And when you shift do you stop throttle and peddling in PAS for a split second -- to save the derailleur from premature wear tear?

I don't understand why you shit gears ? 🤔 This motor is so powerful that you could only use one gear, probably the fastest, instead of shifting constantly 🤔
shifting gears is the best way to keep your motor last long. If you stay to only one gear , you will blow the motor up soon.
