Bosch® Active Drive Unit
Universal performance
Adapted from Bosch’s German-engineered automotive applications, the Active Drive Unit can take you up to 25 km per hour (20 mph in the U.S.) and operates dependably—day in and day out. Its high-performance electronics, whisper-quiet operation, and low-levels of vibration are remarkable—especially given the lightweight, ergonomic design.
Sophisticated Software
3 sensors continuously monitor your pedaling power, cadence, and speed at a rate of 1,000 highly precise measurements per second. Those measurements are then fed into the motor to give you just the right amount of power based on the terrain so that your ride is smooth and natural-feeling. No sudden power spikes.
Quiet and Smooth
Precise motor control and rapid processing of sensor signals ensure minimum levels of noise and vibration.
Rugged and Durable
The well-thought-out design prevents chain derailments, thwarts improper loading, and reduces wear. An integrated stone chip and spray water protection make the drive unit extremely rugged.
