Confirm wheel size
Please measure the size of your bicycle wheel as shown in the picture and choose the right size conversion kit.
Types of flywheels
If you choose a rear motor conversion kit, please confirm whether the flywheel of your bicycle is a cassette or freewheel.
Pedal sensor
The kit comes with a pedal sensor that fits most bikes. If you can't fit it on your bike, don't worry, we offer sensors with other mounting methods. You can find one that fits your bike on our accessories page or contact us.
Brake sensor
The kit comes with a normal cable brake power-off brake handle. If your bike has hyraulic brakes, you will need to purchase an additional hyraulic brake sensor to disconnect the motor power when braking.
