Good morning , I did not understand how the motor drives , because it is linked to a plastic gear that is silly , it does not hold , as it has an internal bearing .
hello I have a small question to ask is the nylon motor pinion for the bbs01,02 motor and the bbshd all identical or not because I am looking to repair one because I bought a nylon pinion for bbs02b is whether it will go on bbs02 or not

Use a synthetic grease mobil 1 or Moly watch heat too I upgraded my stock controller to Luna after blowing 2 an they always ran hot on throttle new controller an nylon gear after 5000 kilometers
One thing I reacted to was the cutting of the seals. This is a VERY BAD IDEA! This will cause it to shift as the two sides will go over and under each other if they're pushed together which will happen if the cable is shifted sideways and the seal will not do its job, not only because of this shifting, but just for being basically destroyed. Also, silicone should be avoided unless it's of such kind that it's not destroying rubber or contains any form of acid as most regular ones do. This acid corrodes things (PCB's and some metals) and dries out rubber. This is also why you shouldn't use shoe polish with silicone in it! on leather as a comparison. I would rather recommend removing the rubber seal and use silicone only, mostly because of what I just wrote, but also to avoid having layers of seals (Rubber + silicone) that breaks easily and is very varying in thickness around. It's easier to make it waterproof that way.
@@Greenbikekit It's still a bad idea, besides, you can put them on and off with a bit of force if you're careful. Also, you should avoid soldering these as capillary effect will make the solder tin crawl under the insulation and you'll get a break in the cable where the solder stops. Think of it like a bunch of pasta straws, if they were glued together at both ends, they wouldn't be very flexible, but if they're only tied they would flex some (As crimping would be the equivalent). Soldering with preventive methods for this problem is cumbersome to say the least. This involves wrapping the insulation with wet cloth to stop the heat along with both flux and solder tin to travel underneath and it requires a bit of practice to make it a good joint!. This is quite useless with small area cables as the heat is pretty difficult to stop from spreading. You should never use additional flux, and what little comes from the solder tin you should allow to evaporate as much as possible on the tip before applying it to the joint. Tricky as hell. Too little flux left and the tin won't flow, too much and it'll flow too well. Also, gluing seals is generally a bad idea unless it's a compound that doesn't dry out rubber, and seeing as how the Chinese like to cut corners, I don't think they would even consider that. Just look at how they designed the PCB for the controller with tons of solder tin instead of putting a few thicker strands of copper where it's needed. I discovered this as I accidentally fried mine and the whole PCB went up in flames due to solder melting and shorting out the entire board, so no, I don't think they'd care about gluing seals using non-corrosive glue.
Guy in this video doesn't replace the locking ring on the superior pinion,which should be replaced above the granny gear,before replacing the cover.Had my bbso2 16 months and after replacing 2 nylon granny gears,ended up upgrading to a metal granny gear,and a cut out when you change gears.Never looked back since.
Thanks for the tip on a metal granny gear, also I think he never changed the locking ring as he is just showing "how to do it" and not actually doing it, you'll also see that he does not change the nylon one either.

Hi ! Great job ! Would it be possible to replace the stator and motor from bbs01 to bbs 02..and use the bbs01 kit structure ?!
No, the bbs02 stator and rotor are larger than bbs01

BBS01 and bbs02 share the same nylon gear, while BBSHD's nylon gear is bigger than BBS01/BBS02's nylon gear.
Thanks for the video. Your link to replace the nylon gear doesn't open, it reads site not found ?🤔

thanks for your kind remind🙂
@@Greenbikekit Thanks for the link.
Does anywhere in the UK do this kind of work? My heads battered watching it
You can replace the gear easily
Need Bafang’s repair shop in SF Bay Area?

How often does this need replacing
It depends. Some riders have a better maintenance for the motor, grease from time to time,
Use a synthetic grease mobil 1 or Moly watch heat too I upgraded my stock controller to Luna after blowing 2 an they always ran hot on throttle new controller an nylon gear after 5000 kilometers
50,000km on mine and never greased the nylon gear

If you don't cut the seals, you need to resolder the bullet connectors. Cutting the seals, and then glue them, Bafang also put glue for these seals.

This guy is very quiet spoken
very quiet video
prob used no copyright music then they flipped the switch
