Whether you're heading to the office in the morning or a restaurant in the evening, Active Line makes urban mobility enjoyable – even during rush hour. Controlled, lightweight and quiet, it is ideal for navigating city streets. Its controlled acceleration and barely perceptible pedal resistance over 20 mph or in Off mode make every ride a pleasant experience. Its elegant design has won a Red Dot Design Award. The drive unit integrates perfectly into the bike frame, making handling and life a little easier thanks to its low weight.

With multi-tooth receiver
The pedal is secured on the crankshaft with the crank arm by means of a multi-tooth receiver.
Motor control
For controlling the drive system
The electronic control centre of the drive ensures smooth delivery of power, processing over 1,000 measured values per second.
Torque sensor
Detects the rider's own pedal power and passes this on to the motor control system
Alongside the cadence and speed sensor, this is the key component for determining riding behaviour.
Electrical Connections
For battery, sensors and light
