Convert your road bike into an electric bike with pedal assist quickly and easily. The system is easily installed by changing the rear wheel and the battery in place of the bottle cage, without altering the bike's aesthetics. The pedal assist sensor is integrated directly into the motor, and the assist control, with its indicator light, is located on the battery cover for convenient and intuitive operation. The range reaches up to 100 km with minimum assistance and 40 km in maximum mode. By deactivating assistance on descents or flat terrain, battery life is significantly increased.
