There is an argument that the entire assembly should have been cleaned and dried before adding new grease. A little messy, but all of the wear particles will continue to wear the components, even with new grease.
Yep. Protip for cleaning grease, diesel, soak it in diesel and use an old toothbrush. If diesel doesn't get it off, gasoline sure will, just be careful if you go with gasoline, it's very flammable.
very helpful, thank you! there is barely any grease in the gears from the factory, so i would personally advise anyone to just go ahead and follow the instructions in this video regardless of how many miles youve put on the motor.
last week i bought a bbs02 and fitted i did 50ish miles and its been noisy so i opened up to add some grease and there was only a tiny bit and found a tiny metal shaving i just packed it like in your video and its quiet now thanks for saving my motor
Thanks for taking the time to produce the video. Excellent. Newbie at bike maintenance. Just like to share the most important part about this whole procedure I learnt. Look carefully at the Crank Puller that you will use. I did not realease it has two parts to it. Make sure you match the size of puller end to mate with the face of crank shaft. I had to modify the small end to make mine fit. Initially, nearly destroyed the crank arm. I've just done 1000km on the bike. There wasn't much grease inside the motor. After following your directions and test riding. Results.....wow, now as smooth as silk. Highly recommend doing it. I also used Mobil grease 28. Expensive, but worth every bit.
Excellent video and well narrated. One constructive comment though...I found it unnecessary to remove the crank on the Bafang BBS01. Simply remove the pedal, then undo the crank ring, slide it over the crank arm to remove, the same for the motor cover. This leaves the gearing exposed for regreasing as you described. Reverse the process to complete the task 👍
Just bought a new BBS02 motor as a backup to the one I've been using for a couple of years. After seeing some of the videos about greasing the motor, I decided to take a look at the situation with the new one. Next to NO grease on the gears! Couldn't see ANY on the meshing surfaces! Greased it thoroughly and will have a look at it again in 1K miles. No doubt greasing it when brand new will help it last a long time.
@@Biktrix so the big question for potential buyers of your brand, do we need to worry about doing this procedure on a brand new bike? Or is Biktrix opening every single Mid Drive and checking/adding grease as required?
I am also using mobile 28. In the next service i will mix mobile 28 with mobil atf 220. Why? Because it gets more liquid and falls down so the gear picks it up all the time. My cover is upgraded made out aluminum and i use allways loctite 5910 as a gasket to prevent it from rain/dirt and also to be tight. This is just my thinking.
Thanks, I have one, and some time will have to open it up, so now I know. We call the Clutch a Sprag clutch in the UK, bit like a one way bearing, also called a sprag bearing.
Allow me to add to the chorus of commentators pointing out that you should always remove every possible speck of old lubricant before adding new. If you are going to do it, do it right.
I think it important to do this level maintenance at the beginning of the motor's life because you can never guarantee how much lubrication you have at the start.
Petroleum base grease is not recommended for nylon gears at all it makes them soft causing more harm than good! Silicon grease is recommended plus it also has the advantage of being dielectric (none conductive) so its save to use around electronic's like the printed circuit board inside there.
@@mr.monitor. That nylon gear will last ages, had the same one in for 4years now and its almost like new, I run full 30amps through it, the only reason I see when users wreck them is from over throttle use or setting the amp current stupidly on the pas settings, that said nothing wrong with steel gear.
@@mikethomas6051 If there was no need, they wouldn't make them. They now make a nylon steel hybrid that is even better for this purpose. People wear them out all the time. I'm glad you had good luck with yours.
I don't get the obsession with so much grease....... over greasing can cause extra friction, loss of power and heat build up. grease is a substitute solution where oil can't be used or easily contained. A good quality grease should be used that matches the material of the gears .....Clean out the old grease before packing with new stuff ......it task is to provide cushioning as well as lubrication. IMHO.
Hmm you used mobil 1 synthetic grease while the recommended is mobilgrease 28. Also only greased half the gears in the motor and no mention of removing the old grease from the gears which will contaminate the new grease. I'll be doing this as soon as the grease and replacement reduction gear turns up but to the entire motor.
i would use a lighter weight grease on the clutch in cold temps that grease may not allow the pawls to release good and may break pawls etc had it happen on rear hubs with similier configurations
Thanks great video iam 8000klm but no noise at all i should soon do this i noticed you have to line up clutch then spin clockwise then all re seat the next part seems a simple process for a beginner thanks for the video
The unit already is delivered properly greased. There is no need to do this- also the reassembly of the cover is very exacting. If not exactly aligned you risk cross threading the screws- then you're really screwed...
@@xJayteee i disassembled the big secondary gear out by unscrewing some two holders from the other side. Cleaned using 99,9% alcohol. After cleaning, added new aeroshell 22 grease to the gear directly and the housing. The bbs02 got much much more quieter and less wear and tear
Yes, perfect thing to do, indeed when you pull the crankshaft out there is a small semi integrated roller bearing, I only apply a small bit of grease on this but not the one on the non drive side.
Y'all missed a Step: Step #1 - Order a NEW Gasket for the cover and have it on hand prior to disasembly. Factory gaskets will more often than not tear to pieces the first time the cover is removed. Any gaps between the cover and case WILL leak grease. Side note: You really only need to lubricate the main output gear. Excess will transfer to the drive pinion.

Mobil Red n Tacky is NOT a synthetic grease but petroleum based so may have an adverse effect in the nylon gears inside the motor. Best stick to synthetic Mobilgrease 28. Shell Aeroshell 22 or Mobil SHC.
@@martinlong8739 1st of all. Red 'N' Tacky is not a Mobil product. It's by Lucas. And 2nd it is indeed a Synthetic Complex Lithium EP grease. The stock nylon gear in the Bafang motors comes from the factory coated in a non-EP White Lithium Grease.
@@SternLX Yes of course, my mistake, as you say it is Lucas, I use Red n Tacky a lot. However it is petroleum based so who knows how it will react with the Bafang nylon gear. It is not synthetic. Check out the Lucas Safety data sheet "The following components are listed: Distillates (petroleum), hydrotreated heavy naphthenic; Distillates (petroleum), solvent-dewaxed heavy paraffinic; Zinc Alkyldithiophosphate" I prefer to use synthetic such a Mobil 28 Mobil SHC or Aeroshell 22. Just out of interest why did you think it was synthetic?
@@manoz6194 Hello Mano, that might be so but personally I prefer to use a synthetic (non petroleum) based grease and I can be sure it wont react and soften the nylon gears. I use Mobil SHC100 or Aeroshell 22. Google this article it may help explain "Hardy Boys Solve The Mystery Of The Nylon Gear Failure On The BBS02"
This is only 1/2 of the job, you definitely have to clean out the old contaminated grease then remove the crankshaft and lubricate the "Needle Bearings" they have very little grease from factory and they are often near dry or starting to rust @ 1500 miles. Not greasing the drive system in its entirety is the #1 cause of BBS02 motor failure, a very expensive mistake.
I’ve just purchased this BBS HD and installed it and wrote it for 200 miles, the issue I’m having is the motor will provide too much resistance or something is to my peddling so anything under three speed on nine speed mode it’s like paddling against the current or as if the brakes were on. I know it’s nothing to do with the wait because for some reason when the motor has been off for a night or a long time and you initially try to pedal without turning the motor on there is no or little resistance it’s only after activating the motor and paddling for a moment that something engages inside which starts the resistance again. Of course the motor works and rolls you up the hill good but the problem is it’s like there is the brakes on all the time which I think can cause extra lots of battery to lose as well as it’s near impossible to go anywhere when the motor is off or in low PAS. I am hoping somebody knows any solution to this I’ve read maybe I have tightened the motor too much as a lot of people recommended it can loosen but also maybe the nylon gear has already went out or they’re just needs to be way more grease inside any help would be appreciated I have not looked inside yet but just disassembled everything
Good video! But the step to get the BBS02 shaft out is missing, it is not just to pull it out as it seems in the video :) you have to remove other side crank and those nuts there.
The steps in the video will help you complete what the video shows. But yes, if you want to fully disassemble the BBS02 you'll need to take the other crank off as well
I'm experiencing a clicking noise with my motor and it only has 300km on it. I'm not sure what the issue is but it sounds like a bearing inside the motor case. Seems odd to me these motors are not prepared for use from the factory or retailer... My bike did not come with any instructions, let alone any recommending opening up the motor to grease it... I love my bike but these are some pretty annoying problems to be having on a brand new bike...
When I did this the motor cover was stuck on to the casing so that I had to pry it apart, then a couple inches of the gasket stuck to the cover the rest to the casing, and it tore at one spot. I applied the grease then I had difficulty getting the cover back on until I rotated the inner gear (ratchet ring ?). So now I guess I'll have to order a gasket and tear into it again.
Did my bbshd greasing from brand new, running really quiet too! ..its quieter than my bafang 500w hub drive, but guess you can't make the hubs as quiet anyway?
If I should add grease to my Bafang BBS02 when there's 1000KM on it, does that mean I have to add grease every 10 - 12 days? Because I commute with my bike about 100 kilometers a day. Like, that doesn't sound right. Can anyone please enlighten me on this matter? Thanks.
The only "Grease" that won't deteriorate the nylon gears is: Black (not grey or white that have different components) Black MOLY GREASE NGLI 2 w/Lithium (thickness) Applied to the metal reduction gears... Reapply after 2k miles or anytime you begin to hear the motor spinning louder. Many have used other greases that break down the nylon gears and cause more problems.. Select the correct one.
@@rdkuless we’ve been rebuilding these longer than bafang and have been supporting warranty for these way longer than Bafang has. Since 2013. We were and still are one of Bafang’s largest customers in Canada. We helped them define service intervals. So, not sure whom you spoke to there but no issues with using Mobil 21 grease. It has no negative effects on the nylon gear. We have over 20k miles tested and our customers have over 300k miles tested.
A big thing with these motors is that a lot of the time they don't come with that much grease in them, so it's more about adding grease than cleaning it
@@Biktrix I hear you, I just don't like to mix different types of grease if I can avoid it. I'm sure its not an issue but just one of those things I try to avoid.
What other grease we can use instead of using mobil 1, mobil 28, aeroshell 22 greases, since these greases are hard to find and expensive in my country, and these aero type greases seems like an over kill for this type of motor
He used Mobil 1 wheel bearing grease, I think. I got some Mobil 28 aircraft grease for lubing bike motors. It’s a little softer than regular Mobil 1 - *which I also have* as a general purpose grease. Another good one is SuperLube grease with Teflon - which I used on installing the forks.
has anyone taken the axle apart to replace the clutch? I've take the snap ring off and everything I can find to remove, but the axle won't slide out from the gear.
Great video, thanks for posting in. Just received the Juggernaut Ultra FS Pro. Is this procedure in the video the same for the Bafang M620 on the Juggernaut Ultra FS Pro? Thanks in advance!
I've done 16,500klms since fitting the BBS02 to my Bianchi hardtail. Had it regreased by the installer at 6mths, then did it myself based on this instructional video...very easy indeed. Extremely happy with the Bafang package 👍
You totally can grease the nylon gear as well! However, that requires more disassembly of the motor than this super quick job which is the focus of this video
3 года назад+2
@@Biktrix I know that! :) I did it as soon as I bought my bbshd. I lubricated the metal gears with black lithium grase, and plastic gear with special white grease. I have now about 4000km (at least 30% of that kilometers at extreme uphills with preaty heavy load (over 100kg) ) and there are no sounds so far! :) electricbike-blog.com/2015/12/23/mobilgrease-28-bbshdbbs02-because-a-good-mid-drive-is-better-seen-and-not-heard/
Hi! A little question: what would it do, like, at -20˚C in winter? Grease would hardened a little bit? If so, is it going to drain the battery a little faster?
-20 shouldn't hurt the rider if they're properly dressed. I'd be more concerned about the battery. Best to keep the battery inside when not in use. While the battery is in use it should create some of it's own heat and not get too cold for a while.
Yes, of course the additional grease will be adding to the internal friction of the gearcase, and moreso when the grease is cold. One way to test this is to put an ammeter on the power leads before greasing and after greasing, and bring the motor up to same speed both times, and compare the amperage draw. Then let it get cold and try it again. With the amount of grease added in this video, the difference could be significant. Remember though, you're only measuring the motor spinning on a stand; it's not really working as it would be on a ride. Maybe less grease, but still have plenty?? Need more data.
nice video thanks. any tips on making the controller last longer? My bbs02b has had two controllers fail both around 400km's. So 800km in and Im already on third controller..
From what I can say after riden for 8400km on the stock controller without any problems. Dont ride it to hard at a high pass level. When the cadence is to low and you are riding into high gears, lots of watts turning into heat, if you possible dont use your gears right. Specially at the summer, if you life in a country with a hot climate. Allways use your gears right, shift low enough when going uphill. If you can feel lot of resistance on your pedals going up, then it will also be very tough for motor, and the watts your motors uses will be send into heat in your controller and tough for motor granny, pinion, nylon gears and motor copper stator windings. Limit your max amps to 18 amp, the controller from the BBS02 cant handle 25 amps for long, BBSHD has a much better controller. reprogram your controller for smoother cycling. Sometimes at summer when i drive at high pass, the controller feels very hot (even below 18 amps)after you recognize this, quickly lower your pass level. I'm going to install an temp sensor (like i read on the internet)to keep an eye on the temperatures of the controller.
From my experience, owning bbshd for 5years or so, I've had one controller error, it happens, my advice is upgrade the motor and battery connection, I had anderson poles and they melted and come loose, went to xt90, disconnect the battery when charging to avoid sparks, don't buy cheap a battery, avoid programming the pas settings to stupid currents and percentage, same goes with the throttle setting ( can cause alot of issues ) being to high power. Bafangs paper gaskets are crap, use some rubber gasket sealant instead, it forms a better waterproof seal, check the sealant that covers the controller so its not getting any moisture in, check all wires to make sure they are not loose, apparently this is the main reason for errors. I've covered over 3000+ miles on one bike and 700 miles on my back up, 1 controller fail and one stator issue.
@@Biktrix understandable but do u know if can it be done? Furthermore, if installed properly can it serve the function without compromising the motors structural integrity 🤔 btw hey thanks for the help awesome video buddy 👍
@@goodboy1269 you will still need to remove the old grease. Simply adding in more grease will only cause more friction and issues that follow due to it.
I inherited a 50 year old lathe that had a motor with grease nipples on it; that allowed grease to be pumped into the bearings. Long story short, I stripped the old motor because it was not running well. The whole of the inside of the motor, including all the electrical windings, were jam packed with grease (some of which was ancient and as hard as soap.).
there must be something comparable in the UK just do some research online. Or ask a car mechanic pretty sure it's just like packing Grease for packing gears and or bearings
@@tallcool1jeff Thanks for your reply, yes I did some research and I purchased some Lucas Xtra Heavy Duty Grease available here in UK and I'm pleased its marine grade and red in colour. Its made in the US but available to purchase here, its on its way. :-)
That is correct! The Ultra 1000 uses the Bafang Ultra motor. It is slightly different to complete this job, so we will have to make a second video for that motor.
Well you can but you have to slide it out of the bottom bracket casing. Not particularly difficult. There is a special tool but i made one out of a bit of tube with slots cut in.
@@magzire There are 2 tools there is the outer nut which can be removed with the big ring spanner that comes with most kits and a tool with 4 prongs on it to undo an internal washer that enables access to the clutch/freewheel. You may be able to use long nose pliers or even a screwdriver instead of the bafang tool.Heres a link to a good article electricbike.com/forum/forum/knowledge-base/motors-and-kits/bbshd/22903-bbs02-clutch-replacement
not 100% sure on this, but at 3:14 there looks like there are a few bolt holes (maybe m4 size?) on the gear if you screw bolts in and tighten them evenly it should force the gear off the housing
Just a regular crank puller! Like this one: www.amazon.com/Park-Tool-Compact-Crank-Puller/dp/B0028YUZSS/ref=sr_1_3?dchild=1&keywords=park+tool+crank+puller&qid=1610143802&sr=8-3
I live here in Seminole Texas and I received a juggernaut and it needs to be oiled can I take it to a shop somewhere do you know here close to Seminole?
They used WAYYYY too much grease. It only needs to be lightly applied and only after the gears have been cleaned beforehand. They didn't even clean the old contaminated grease off of the cover. When they took it apart note how much grease was on the cover? After greasing your bike as they show and after using your bike for a month or so pull the cover again and see the mess left behind from the excess grease! It has no place to go and after awhile it will force itself into everywhere, even places it isn't supposed to go.
We appreciate your comment, but in the 10k+ Bafang mid-drives that we've sold, this is the best process we have found. Many of the greasing issues arise in these motors because Bafang doesn't put enough in from the factory
@@Biktrix Thank you for the quick reply. I have had the same issues with the final drives on shaft driven motorcycles. The solution was to clean and then apply a small amount of grease to the splines each time the rear wheel was changed. I realize the Bafang motor is a different item, however grease will get into everything and too much grease creates its own issues. A small amount, perhaps a thin line down the centre of the drive wheel or a small amount applied with a small grease gun to get into the root of the gear teeth would work as effectively? Repeated every year perhaps as part of ones annual maintenance process?
So no cleaning, just shove more grease in it?? How about the primary drive gear and clutch bearing (sprag)?? Seems like a waste of time and grease w/o any cleaning or completing the job.
You can take this maintenance as far as you want, most riders will be totally fine with this quick job that will improve the performance and lifespan of their motor. Many times, these motors don't come with packed with excess grease to clean off

@@martinlong8739 1st of all. Red 'N' Tacky is not a Mobil product. It's by Lucas. And 2nd it is indeed a Synthetic Complex Lithium EP grease. The stock nylon gear in the Bafang motors comes from the factory coated in a non-EP White Lithium Grease.
@@SternLX Yes of course, my mistake, as you say it is Lucas, I use Red n Tacky a lot. However it is petroleum based so who knows how it will react with the Bafang nylon gear. It is not synthetic. Check out the Lucas Safety data sheet "The following components are listed: Distillates (petroleum), hydrotreated heavy naphthenic; Distillates (petroleum), solvent-dewaxed heavy paraffinic; Zinc Alkyldithiophosphate"
I prefer to use synthetic such a Mobil 28 Mobil SHC or Aeroshell 22.
Just out of interest why did you think it was synthetic?
@@JohnSmith-ch9lp I've seen forum posts where remote control users put red n tacky in their RC cars and have not had a problem on plastics?
@@manoz6194 Hello Mano, that might be so but personally I prefer to use a synthetic (non petroleum) based grease and I can be sure it wont react and soften the nylon gears. I use Mobil SHC100 or Aeroshell 22. Google this article it may help explain "Hardy Boys Solve The Mystery Of The Nylon Gear Failure On The BBS02"
This is only 1/2 of the job, you definitely have to clean out the old contaminated grease then remove the crankshaft and lubricate the "Needle Bearings" they have very little grease from factory and they are often near dry or starting to rust @ 1500 miles. Not greasing the drive system in its entirety is the #1 cause of BBS02 motor failure, a very expensive mistake.
Does this apply to the bbshd as well?
I’ve just purchased this BBS HD and installed it and wrote it for 200 miles, the issue I’m having is the motor will provide too much resistance or something is to my peddling so anything under three speed on nine speed mode it’s like paddling against the current or as if the brakes were on. I know it’s nothing to do with the wait because for some reason when the motor has been off for a night or a long time and you initially try to pedal without turning the motor on there is no or little resistance it’s only after activating the motor and paddling for a moment that something engages inside which starts the resistance again. Of course the motor works and rolls you up the hill good but the problem is it’s like there is the brakes on all the time which I think can cause extra lots of battery to lose as well as it’s near impossible to go anywhere when the motor is off or in low PAS. I am hoping somebody knows any solution to this I’ve read maybe I have tightened the motor too much as a lot of people recommended it can loosen but also maybe the nylon gear has already went out or they’re just needs to be way more grease inside any help would be appreciated I have not looked inside yet but just disassembled everything
Since it's been 9 months did more grease or anything help?
In EU it's hard to get Mobile 28, what are the alternatives?
WHat is noises are coming from the bottom bracket?
hello i have bbs02 750 that work and stop and then work can you advise me what wrong and how to fix it, thanks
Bugger. Started on my one but it's nothing like that one of yours. Haha. Not sure what motor I've got now. It's a Bafang in frame one.
Very good info,that helped me out heeps good work cheers.
Glad it helped you!
Good video! But the step to get the BBS02 shaft out is missing, it is not just to pull it out as it seems in the video :) you have to remove other side crank and those nuts there.
The steps in the video will help you complete what the video shows. But yes, if you want to fully disassemble the BBS02 you'll need to take the other crank off as well
thats why im a fan of bafang.
I'm experiencing a clicking noise with my motor and it only has 300km on it. I'm not sure what the issue is but it sounds like a bearing inside the motor case. Seems odd to me these motors are not prepared for use from the factory or retailer... My bike did not come with any instructions, let alone any recommending opening up the motor to grease it... I love my bike but these are some pretty annoying problems to be having on a brand new bike...
When I did this the motor cover was stuck on to the casing so that I had to pry it apart, then a couple inches of the gasket stuck to the cover the rest to the casing, and it tore at one spot. I applied the grease then I had difficulty getting the cover back on until I rotated the inner gear (ratchet ring ?). So now I guess I'll have to order a gasket and tear into it again.
What's your opinion on marine grease?
Did my bbshd greasing from brand new, running really quiet too! ..its quieter than my bafang 500w hub drive, but guess you can't make the hubs as quiet anyway?
Possible Mobil 1 Fully Synthetic Grease?
If I should add grease to my Bafang BBS02 when there's 1000KM on it, does that mean I have to add grease every 10 - 12 days? Because I commute with my bike about 100 kilometers a day. Like, that doesn't sound right. Can anyone please enlighten me on this matter? Thanks.
Just check it every few weeks or if the motor makes louder than normal grinding noise
The only "Grease" that won't deteriorate the nylon gears is: Black (not grey or white that have different components) Black MOLY GREASE NGLI 2 w/Lithium (thickness) Applied to the metal reduction gears... Reapply after 2k miles or anytime you begin to hear the motor spinning louder. Many have used other greases that break down the nylon gears and cause more problems.. Select the correct one.
Mobil 21 works great.
@@Biktrix until it breaks down the nylon gears and voids the warranty..! You didn't contact Bafang Warranty dept did you?
@@rdkuless we’ve been rebuilding these longer than bafang and have been supporting warranty for these way longer than Bafang has. Since 2013. We were and still are one of Bafang’s largest customers in Canada. We helped them define service intervals. So, not sure whom you spoke to there but no issues with using Mobil 21 grease. It has no negative effects on the nylon gear. We have over 20k miles tested and our customers have over 300k miles tested.
I personally would have wiped as much of the old grease off as I could, didn't seem like you wiped off any at all.
A big thing with these motors is that a lot of the time they don't come with that much grease in them, so it's more about adding grease than cleaning it
@@Biktrix I hear you, I just don't like to mix different types of grease if I can avoid it. I'm sure its not an issue but just one of those things I try to avoid.
there is a benefit of removing the old dirty grease first.
What would you use? I am about to do this to two BBS02B motors.
@@skullparty7638 any good marine grease synthetic best bet
What other grease we can use instead of using mobil 1, mobil 28, aeroshell 22 greases, since these greases are hard to find and expensive in my country, and these aero type greases seems like an over kill for this type of motor
Which country
Idk if its fast or slow maybe just look up fast machine Grease or high rpm grease
Was there no grease from stock
very helpful for your customers, thank you
Our pleasure!
Hello, what do you use for grease? And you put it on every how many miles? Thank you
He used Mobil 1 wheel bearing grease, I think.
I got some Mobil 28 aircraft grease for lubing bike motors. It’s a little softer than regular Mobil 1 - *which I also have* as a general purpose grease.
Another good one is SuperLube grease with Teflon - which I used on installing the forks.
you should clean as much of the old grease and grim off before putting new grease on
I cant find any aircraft grade grease where i live and importing it is costly 50$+ .... any cheaper alternatives?
what Penrite High Temperature Wheel Bearing Grease 450g Cartridge is good?
Any guides on M800 motor?
has anyone taken the axle apart to replace the clutch? I've take the snap ring off and everything I can find to remove, but the axle won't slide out from the gear.
what is the usual going rate for this service at a shop ? seems like it takes about 20 mins or less
This may be too late but I was just at the biktrix shop today for my new bike and they said it costs $200 CAD for this service.
That’s a very solid custom frame! What are the details?
Our Juggernaut Classic Duo and Stunner X bikes have this style frame.
Is there a pattern for the bolts?.
Is there torque lbs?.
If I find it I'll post it, unless you already know.
6Nm
can i also use a different grease? because this one is not available in my country
Motul 80w-90 scooter gear oil.
Great video, thanks for posting in. Just received the Juggernaut Ultra FS Pro. Is this procedure in the video the same for the Bafang M620 on the Juggernaut Ultra FS Pro? Thanks in advance!
It is a different procedure! We'll have a video on this later
do i have to remove the battery compltetly, isnt it enough to just switch the battery off at the rear?
It's best to fully disconnect the battery
hey BBS02 users, what mileage did you make? and how does it work now?
I made 3000km and it runs like a new one (no regreasing so far)
Just doing it now after 2000km, original grease is black but not dirty or with particles.
7500km now, without opening/regreasing
I've done 16,500klms since fitting the BBS02 to my Bianchi hardtail. Had it regreased by the installer at 6mths, then did it myself based on this instructional video...very easy indeed. Extremely happy with the Bafang package 👍
Why you didn't put grease at nylon gear? 🤔
You totally can grease the nylon gear as well! However, that requires more disassembly of the motor than this super quick job which is the focus of this video
@@Biktrix I know that! :) I did it as soon as I bought my bbshd. I lubricated the metal gears with black lithium grase, and plastic gear with special white grease. I have now about 4000km (at least 30% of that kilometers at extreme uphills with preaty heavy load (over 100kg) ) and there are no sounds so far! :)

Where can I get Mobil 1 Synthetic Grease in Canada?
What frame is that fat bike? please and thank you.
Hi, great video. Just bought my 1st Bafang BBS202B - Should I grease it up before I install and use, or after a while?
That couldn't hurt!
Hi! A little question: what would it do, like, at -20˚C in winter? Grease would hardened a little bit? If so, is it going to drain the battery a little faster?
Great question! The grease will be fine, just have your cadence nice and high to so the motor spins quickly and efficiently
@@Biktrix At -20C the grease would be doing much better than the rider.
-20 shouldn't hurt the rider if they're properly dressed. I'd be more concerned about the battery. Best to keep the battery inside when not in use. While the battery is in use it should create some of it's own heat and not get too cold for a while.
Yes, of course the additional grease will be adding to the internal friction of the gearcase, and moreso when the grease is cold. One way to test this is to put an ammeter on the power leads before greasing and after greasing, and bring the motor up to same speed both times, and compare the amperage draw. Then let it get cold and try it again. With the amount of grease added in this video, the difference could be significant. Remember though, you're only measuring the motor spinning on a stand; it's not really working as it would be on a ride. Maybe less grease, but still have plenty?? Need more data.
How often you do this ?
Thank you for sharing!
Thanks for watching!
Thought a torque wrench would be used at some point, there must be torque settings for those bolts
is it the same process for the bafang ultra?
The process is a little different for the Ultra! We'll make a separate video for that
I bet this should be done when the bike is new. The grease they use in the factory prob isnt very high quality.
Not really needed when new from our experience.
@@Biktrix When should it be greased then? I just brought one new and was thinking about greasing it immediately.
@@X6800 doesn’t hurt to do it right away but will probably run with no issues for a few thousand miles
Is there an alternative to use instead of Mobil 1 as I’m in London and we don’t have that unless I pay for shipping from USA 🤪
Motul 80w-90 scooter grease. I used motul in my Porsche.
nice video thanks. any tips on making the controller last longer?
My bbs02b has had two controllers fail both around 400km's.
So 800km in and Im already on third controller..
From what I can say after riden for 8400km on the stock controller without any problems. Dont ride it to hard at a high pass level. When the cadence is to low and you are riding into high gears, lots of watts turning into heat, if you possible dont use your gears right. Specially at the summer, if you life in a country with a hot climate. Allways use your gears right, shift low enough when going uphill. If you can feel lot of resistance on your pedals going up, then it will also be very tough for motor, and the watts your motors uses will be send into heat in your controller and tough for motor granny, pinion, nylon gears and motor copper stator windings. Limit your max amps to 18 amp, the controller from the BBS02 cant handle 25 amps for long, BBSHD has a much better controller. reprogram your controller for smoother cycling. Sometimes at summer when i drive at high pass, the controller feels very hot (even below 18 amps)after you recognize this, quickly lower your pass level. I'm going to install an temp sensor (like i read on the internet)to keep an eye on the temperatures of the controller.
From my experience, owning bbshd for 5years or so, I've had one controller error, it happens, my advice is upgrade the motor and battery connection, I had anderson poles and they melted and come loose, went to xt90, disconnect the battery when charging to avoid sparks, don't buy cheap a battery, avoid programming the pas settings to stupid currents and percentage, same goes with the throttle setting ( can cause alot of issues ) being to high power. Bafangs paper gaskets are crap, use some rubber gasket sealant instead, it forms a better waterproof seal, check the sealant that covers the controller so its not getting any moisture in, check all wires to make sure they are not loose, apparently this is the main reason for errors. I've covered over 3000+ miles on one bike and 700 miles on my back up, 1 controller fail and one stator issue.
where can i find a frame like this?
Once you have it apart, what do you think about adding a grease fitting?
We don't recommend adding any fittings or modifying the motor casing in any capacity
@@Biktrix understandable but do u know if can it be done? Furthermore, if installed properly can it serve the function without compromising the motors structural integrity 🤔
btw hey thanks for the help awesome video buddy 👍
@@goodboy1269 you will still need to remove the old grease. Simply adding in more grease will only cause more friction and issues that follow due to it.
@@Biktrix Good to know! Thanks a bunch
I inherited a 50 year old lathe that had a motor with grease nipples on it; that allowed grease to be pumped into the bearings. Long story short, I stripped the old motor because it was not running well. The whole of the inside of the motor, including all the electrical windings, were jam packed with grease (some of which was ancient and as hard as soap.).
Helpful ta
Great video but I'm unable to purchase the grease in the UK. What other options of Grease please?
there must be something comparable in the UK just do some research online. Or ask a car mechanic pretty sure it's just like packing Grease for packing gears and or bearings
@@tallcool1jeff Thanks for your reply, yes I did some research and I purchased some Lucas Xtra Heavy Duty Grease available here in UK and I'm pleased its marine grade and red in colour. Its made in the US but available to purchase here, its on its way. :-)
So the jauggernaut ultra 1000 has a different mid drive motor? What is it called. I have the 2019 model
That is correct! The Ultra 1000 uses the Bafang Ultra motor. It is slightly different to complete this job, so we will have to make a second video for that motor.
@@Biktrix thanks how often for mine should you grease?
@@rushtonworks9186 Ultra motors can be good for 2000km plus before greasing, but it is all up to the owner's preference and riding habits!
Not much really to do on the bbs02, can't grease the clutch
Well you can but you have to slide it out of the bottom bracket casing. Not particularly difficult. There is a special tool but i made one out of a bit of tube with slots cut in.
@@JohnSmith-ch9lp the bafang tool for loosing the nut on bb? I have that or there's another?
@@magzire There are 2 tools there is the outer nut which can be removed with the big ring spanner that comes with most kits and a tool with 4 prongs on it to undo an internal washer that enables access to the clutch/freewheel. You may be able to use long nose pliers or even a screwdriver instead of the bafang tool.Heres a link to a good article electricbike.com/forum/forum/knowledge-base/motors-and-kits/bbshd/22903-bbs02-clutch-replacement
On my BBSHD motors, when you remove the cover the gearwheel comes with it and I can´t pry it apart to get to the clutch. Is there a trick?
not 100% sure on this, but at 3:14 there looks like there are a few bolt holes (maybe m4 size?) on the gear if you screw bolts in and tighten them evenly it should force the gear off the housing
Thanks Gramps, I'll try that next time I grease the motor.
I have done 1800km on my BBS02. I don't think there is any noise. Should I do this now or wait for noise?
If your motor is still quiet and functioning as new, there should be no immediate need to open up the motor. However, adding more grease won't hurt!
@@Biktrix it will add more longchievity to your motor that's the main reason to do it .
I made 3000km on BBS02, it is still running quiet on 'factory' grease. Opening the motor is allways a risky job
Should just take the cover off when new and grease it I’m sure they don’t use enough
That's an option as well!
i must redo mine
What do you use to pull the Crank arm off? Where can I find it? Is it specific to Bafang? Thank you
Just a regular crank puller! Like this one: www.amazon.com/Park-Tool-Compact-Crank-Puller/dp/B0028YUZSS/ref=sr_1_3?dchild=1&keywords=park+tool+crank+puller&qid=1610143802&sr=8-3
Can this be done with the Ultra as well?
It can be done! The Ultra generally needs to be greased less, and is slightly more complex so we will need to show that in another video
I previously bought molygrease. Will this be just as good?
We recommend the Mobil 28 grease
I used Lucas red and tacky which is similar to mobil 28 in this video but much cheaper. Ive heard the moly grease is bad for the nylon gear
Must be silicon based with anything plastic. Petroleum based grease will slowly degrade and some cases soften/melt plastic parts.
These engine don't need grease below 25000km we sold many of them the grease can't dissappear there only little is needed not so much like this video
It dont need that much at all . The centerfugall spin will make the grease fly out onto the case . I greased mine but not as much .
In our experience, this is just enough grease :)
Grease the bearings too.
decent vid, probably could been half this length.
2x speed :p
@@Biktrix but then yall sound like squirrels!
It's poor practice to mix greases without cleaning off the old stuff first.
I live here in Seminole Texas and I received a juggernaut and it needs to be oiled can I take it to a shop somewhere do you know here close to Seminole?
They used WAYYYY too much grease. It only needs to be lightly applied and only after the gears have been cleaned beforehand. They didn't even clean the old contaminated grease off of the cover. When they took it apart note how much grease was on the cover? After greasing your bike as they show and after using your bike for a month or so pull the cover again and see the mess left behind from the excess grease! It has no place to go and after awhile it will force itself into everywhere, even places it isn't supposed to go.
We appreciate your comment, but in the 10k+ Bafang mid-drives that we've sold, this is the best process we have found. Many of the greasing issues arise in these motors because Bafang doesn't put enough in from the factory
@@Biktrix Thank you for the quick reply. I have had the same issues with the final drives on shaft driven motorcycles. The solution was to clean and then apply a small amount of grease to the splines each time the rear wheel was changed. I realize the Bafang motor is a different item, however grease will get into everything and too much grease creates its own issues. A small amount, perhaps a thin line down the centre of the drive wheel or a small amount applied with a small grease gun to get into the root of the gear teeth would work as effectively? Repeated every year perhaps as part of ones annual maintenance process?
So no cleaning, just shove more grease in it?? How about the primary drive gear and clutch bearing (sprag)?? Seems like a waste of time and grease w/o any cleaning or completing the job.
You can take this maintenance as far as you want, most riders will be totally fine with this quick job that will improve the performance and lifespan of their motor. Many times, these motors don't come with packed with excess grease to clean off
You need to regrease the nylon gear as its done badly from factory
That's a good thing to do as well! We didn't include it in this video as it is a little more in-depth than this super quick job
Is there a tutorial for that?
Which part is the nylon gear
