24V36V250W Electric Conversion Kit for Common Bike Left Chain Drive Customized for Electric Geared Bicycle Derailleur

Features & details Features The motor kit is for bikes that use V brakes on the rear wheel.

If your bike uses disc brake or coaster brake, this kit does not compatible with that bike, please choose other kits.

If you can not sure your bike type, please send me your bike picture, so I can recommend you the correct kit.

This kit just for people riding bike easier, it is not fast (26-inch bike can run about 20km/h), you'd better pedal with the motor power, this can ride longer, please understand.

The difference between 24V and 36V is the working current, if you want to ride longer, I recommend 36V kit.
