BBS02 Custom Build Kit

  • Sale

This Bafang kit contains all the hardware for mounting plus the main electrical cable and the speed sensor kit. All other items can be selected below to build the exact kit you require including throttle, Ebrakes, chainring, display, and optional items.


We offer the BBS02 in 3 configurations for standard 68/73mm bottom brackets. The most powerful motors feature a 48v motor running 750w, and the least powerful motor runs 36v with 500w.  If you have a 100mm or 120mm fat bike, we also sell custom modified 48v / 750w BBS02 motors built using our bottom bracket extension kit.

Main Ebus Cable

Select your E-Bus cable type. Choose Magura cable if you wish to run Magura MT5e brakes, otherwise choose the standard E-bus cable.  This cable is included in the kit price.

Bottom Bracket Adapter
Crank Arms


Choose your chainring based on your gearing and chainline needs.  Larger front cogs mean higher top speeds at the expense of climbing ability.




Brake sensors cut motor power instantly and improve safety.  Choose between simple sensors to entire brake systems.


Stabilizer Bar

A stabilizer bar is strongly recommended for all builds to keep your motor in place and prevent damage to your bottom bracket shell

Main Ebus cable Extension
Speed Sensor Extension
Throttle/Brake/Shift Sensor Extension
