Bafang motors are fitted to thousands of e-bikes and are the most popular choice for electric bike conversion kits. They are tough and easy to work on, but controllers, connectors, sensors and internal gears do wear, especially on bikes used hard all year round.

Our workshop diagnoses Bafang faults by testing each part of the system, then repairs or replaces only what has failed. We can also fit Bafang conversion kits and set them up to UK electric bike (EAPC) rules, so your bike stays road legal.
