This kit includes a 250w brushless motor, mounting bracket, control unit rated to the motor, chain and rear sprocket. The parts are a direct fit to the revvi 12" and 16" bike - select bike size. The kit increases the acceleration and torque of the bike. 

 

You can choose from 2 sprocket sizes on the motor: 

 

13T - More acceleration less top speed

You can choose from 3 control units: 

 

Slow Start - 2 speed settings - Slow start with 2 speed settings

Slow Start - 3 speed settings - Slow start with 3 speed settings​

Fast Start - 2 speed settings - Once fitted the power delivery is much quicker. The top speed is the same but the bike accelerates much faster with 2 speed settings

Fast Start - 3 speed settings - Once fitted the power delivery is much quicker. The top speed is the same but the bike accelerates much faster with 3 speed settings

 

You can also choose to have a sprocket only, or a sprocket/freewheel unit. See pictures. 

 

Please note: Special tools will be required to remove the freewheel from your wheel to change the sprocket! You can remove it using a vice and punch or a freewheel removal tool.
