The ideal drive for every situation
Seamless or powerful – most importantly natural. Drive units from Bosch eBike Systems give you a unique riding sensation. Three sensors measure the rider's pedal power, cadence and speed over 1,000 times per second. This facilitates an organic interplay between you and your eBike. The drive unit of the smart system, the new system generation of Bosch eBike Systems, ensures a unique eBike experience. The smart system combines sophisticated high-quality eBike components with digital functions, is fully connected and always up-to-date thanks to regular updates over-the-air.

The high-quality drive units from Bosch eBike Systems are the power behind your eBike. The gear arrangement ensures optimal integration from a design/technical perspective and increases ground clearance. The compact volume reduces the weight and the pedal distance, enhancing the ergonomics of your pedelec. The Active Line, Active Line Plus and Performance Line CX eBike systems have received the Red Dot Award for product design.
