Technical information

The ERZMO® MS 1 is designed for cargo bicycles used as delivery or freight vehicles, company vehicles or for transporting people. Our drive features a robust and durable design. With its excellent torque, loads of up to 300 kg can be moved easily. Therefore, it is particularly suitable for demanding applications.


Functional principle

When the pedals of the cargo bike are pressed, the ERZMO® MS 1 drive pushes the rear axle via a single roller chain. There, the integrated 3-speed gearbox is not integrated into the power flow of the drive, so that the pedal force has no influence on the motor power. The driver sets the required torque exclusively with the handle and supports the drive only by pedaling. The motor regulates the speed (per minute) and the corresponding tempo.
