Confirm Wheel Size
Please measure the size of your bicycle wheel as shown in the picture and select the right size conversion kit.

Types of Flywheels
If you choose a rear motor conversion kit, please confirm whether your bicycle has a cassette or a freewheel.

Pedal Sensor
The kit includes a pedal sensor that fits most bikes. If it doesn’t fit your bike, don't worry—we offer sensors with different mounting options. You can find one that works for your bike on our accessories page or contact us for assistance.

Brake Sensor
The kit comes with a normal cable brake power-off handle. If your bike has hydraulic brakes, you'll need to purchase an additional hydraulic brake sensor to cut off the motor power when braking.

Motor Fit & Tire Size
Whether you choose a front or rear motor, you’ll need to check the dimensions of both your front and rear forks, as well as the size of your quick release system, to ensure they can accommodate the motor.
Additionally, make sure the tires on your bike are compatible with our wheels.
