The ideal drive for every application
Controlled or powerful support - the main thing is it feels natural. Drive units from Bosch eBike Systems are pedal-assist, Class 1 (up to 20mph) and Class 3 (up to 28mph), which means that the drive unit amplifies your pedal power. Three sensors measure pedal power, cadence, and speed at a rate of over 1,000 times per second. This enables organic interaction between you and your eBike. The drive unit of the smart system, the new system generation of Bosch eBike Systems, also ensures a very personal eBike experience. The smart system combines high-quality eBike components with digital functions, is fully connected and always up to date thanks to over-the-air updates.
