The motor

Powerful, reliable and proven – that’s Bosch motors. When your pedalling power and motor assistance work together, you get exactly the performance you need when out and about.

The driving force of Bosch motors ensures that you reach any destination. Its integration into the bottom bracket ensures a low centre of gravity, directional stability and the direct transfer of force to the rear wheel by a chain or belt. The driving force of the e-bike is controlled by the pedals: the harder you pedal, the more the electric drive assists you – stop pedalling and the motor stops, but you keep on rolling.

The low-maintenance motors with gear detection have an electronic control unit with a 32-bit processor and sensors for power, pedalling rate and speed. The higher the power, the higher the torque and therefore the faster the acceleration. A pushing and starting aid helps your bike up hills at 6 km/h at the touch of a button, even if you are not sitting on the saddle.
