250w Brushless Upgrade Kit - To fit Revvi 16" electric balance bikes
 
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 16" bike. The kit increases the acceleration and torque of the bike. This motor is also more efficient then the standard 16" motor so your battery should run for longer. 
 
You can choose from 2 sprocket sizes on the motor: 
 
13T - More acceleration less top speed
15T - Less acceleration more top speed
 
You can choose from 3 control units: 
 
Standard - 2 speed settings - Slow start with 2 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
 
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.
