Fat Bike Kit-Bafang BBS02B


This is the original Fat bike kit. Designed and assembled in California. 

This Bafang “Fatbike” Mid Drive consists of a modified Bafang BBS-02B drive with an extended axle to accommodate the installation on a bike with a 100mm or 120mm bottom bracket. The modification of the Bafang drive to use the extended axle is completed by California Ebike and shipped as a sealed and whole unit in a kit.

  • Installs on most bikes with a 100mm or 120mm bottom bracket
  • BBS-02B 750 watt drive is used
  • Battery sold separately

The kit includes the same list of parts as the standard Bafang BBS-02 conversion kit we sell. This allows the installation of the modified BBS-02 drive to be installed and bolted on similar to a standard unit.

For additional information, please refer to our Bafang “100 mm” BBS-02 Mid Drive product announcement.
