The clutch has two versions, the old version has 4 key slots and the new version has only one key slot, please check your own motor clutch before making the order. By the way, the new clutch can be used for both BPM motors or Bafang CST motors(produced after 2014).

The clutch includes gears. 

We stopped selling the old version BPM/CST/RM G070 motor clutch because according to a few customer's feedback, the old version clutch cannot fit their BPM/CST/H610/H620 hub motor.

We are currently selling 3 types of Bafang hub motor clutches. The difference for the three types clutch: BPM/CST/H610 clutch uses 42T nylon gear; SWXK/SWXH/RM G010 clutch uses small 36T nylon gear(we have this nylon gear available on our website); SWX02 clutch uses bigger 36T nylon gear(48mm in diameter, 14mm in thickness; we don't have this big 36T nylon gear available currently). The only difference for the two SWX02/RMG 06 fatbike motor clutches is the inner bearing of the nylon gear, theoretically, the two clutches are compatible with each other.

Some Bafang motors share the same motor clutch, therefore if you don't know what Bafang model your motor is, you can measure the dimension of your original clutch, if it is the same dimension as ours, then you can order it for your motor.

All our motor clutches are sourced directly from Bafang.
