Bafang BBS brake, brake sensor or throttle extension cable. If you build an electric tri-cycle or cargo bike, this extension cable is a must because the original brake and throttle of the bbs kits are too short. The price is for one cable, if you need it for the brake, you may need to order two of this cable.

This wire is also suitable for Ultra M620 or Max drive M400 mid motor.

Bafang mid crank kit(BBS01, BBS02, BBS03/BBSHD) clutch replacement spare parts; the price includes two sets of thrust ball bearing(each bbs kit needs two sets of thrust ball bearings). There are also two axle retaining lock nuts(4 key slots, a thick one and a thinner one) to lock the thrust bearings in the bbs axle, if your lock nuts are broken, you can order them on our website as well. These are needed when replacing the clutch; if you need tools for replacing these washers and lock nuts, please order the bbs axleremover/spanner/wrench on our website.

Bafang BBS01/BBS02 finger freewheel/ pedal freewheel/pawl clutch for replacement.

If your Bafang BBS works normally by throttle, but bike pedals do not work and spin around freely, the pawl clutch of the bbs may be blown, and replacing the freewheel may solve the BBS problem.  The BBSHD pedal freewheel is different with BBS01/BBS02B pedal freewheel.

Bafang BBS01, BBS02, BBS03/BBSHD kit spare part: BBS PAS circuit with connector for replacement. It can plug into the BBS controller directly. If your kit cannot work with padel, but it can work with throttle, you can consider to replace the PAS circuit.   To remove or install the PAS magnet, you may need a special plier and you can order the tool on our website too.
