Details

Introducing the new Commuter with a Bafang 750W motor (85 Nm Max Torque), Hydraulic disc brakes, suspension fork, 720 Wh battery, and a torque sensor, where the assistance provided is based on the pedaling force being applied. So the harder you pedal, the more assistance you will obtain. This creates a more natural riding experience. The 27.5 x 2.4" Kenda puncture resistant tires make your ride ultra smooth. The front and rear integrated lights allows you to see and be seen at night. Fenders and rear rack are also included.
