The ideal eBike motor for every situation

The pedal-assist electric bike motor, also called a drive unit, is at the heart of the Bosch eBike System. All Bosch drive units are designed to deliver smooth and predictable power, perfectly complementing the rider’s pedaling, and amplifying the rider’s input by up to 340%. We offer a complete line of mid-drive motors — ranging in power output — for every category of electric bicycle: cargo, hybrid, city bike and, of course, electric mountain bikes. See the lineup below and ask for a Bosch-equipped eBike at a dealer near you.
