Things to think about before purchasing rear drive conversion kits:
- The rear drive motors are only compatible with a 3speed, 6speed or a 7speed freewheels (not compatible with a cassette type gear). If you have a single speed bike, you can install a 3speed freewheel for compatibility (and use only one of the 3 speeds).
- The rear forks on your bike need to have 135mm clearance between the drop-outs (which is the case with the vast majority of bikes)
- The LCD computer is necessary to unlock the full power of these high power motors. Can be purchased at a later stage if full power is not immediately needed.
- The electric brake levers supplied with the kits are mechanical. I.e. they are not compatible with hydraulic brakes or brakes that are combined with gear levers. However, installing the brake levers are not a necessity and the kit will work fine without them. Moreover, the throttle is spring-loaded, i.e. it will cut the power whenever the thumb is released from it for safety.
