E-bike motor king Bosch launches its first hub motor for electric bicycles

Bosch is entering urban e-bikes with its first rear hub motor, the Hub Line, a lightweight, connected drive unit designed for commuters. The motor delivers 45 Nm of torque, weighs 2.3 kg, and uses onboard sensors to tailor output to riding behavior, coordinating in real time with electronic shifting systems, including automatic gearboxes. It pairs with Bosch’s PowerTube 360 battery (2.1 kg, 68 mm diameter) for up to 80 km of pedal assist. A new ConnectModule provides GPS, cellular connectivity, motion detection, and an audible alarm, while Bluetooth Low Energy helps locate bikes in low-signal areas. Bosch frames these features within its Flow+ subscription ecosystem.
