Electric Bike Motor Reduction Nylon Gear for BAFANG BBS02B and BBSHD Ebike Conversion Kit Mid Drive Motor
If you apply too much power while in the wrong gear you can strip them creating a problem referred to in the community as “peanut butter gear”.
Nylon is a necessary evil is because if steel gears were used the BBSHD would be very noisy.
The nylon primary reduction gear is one of the weak links in the Bafang motor system.
There are two models, one is for BBSHD(BBS03); one is for BBS02B. Please kindly note the depth is 3mm, is for the new version BBS. DO NOT fit for the old version(the depth is 6mm). Check carefully before you purchase.
