All the needed components in a tiny and elegant rear bike hub. Brushless motor, batteries, electronics and sensors. Everything stays within 180 mm diameter and 120 mm width. With a battery capacity of 173 Wh and a weight of just 3 kg our all in one hub has the highest energy/weight ratio on the market. 

Brake-regen for maximum efficiency. 

Bluetooth connectivity allows you to connect your smartphone* (iOS and android supported) to your Zehus device to select your favourite power mode, manage your trip data and even lock the bike. Thanks to the bitride app, your smartphone acts also as a gateway throughout the bitride community, allowing you to access to services such as online diagnosis, bike-oriented navigation, mobility stats and other social functions (e.g. find a stolen bike).




The super-flat, only ten millimetre wide planetary gear blends in alongside the chain wheel in a modest manner, being easily shifted by a kick with the heel on the shift button. Wireless, without cable operation, levers or derailleurs, the gearbox shifts reliable and safely. High efficiency is granted by sun and planetary cogs meshing ideally. High quality materials ensure a high lifespan and lots of joy with the gear, even if it is heavily under load. The low-maintenance gearbox can be easily shifted while the bike stands or is under pressure.

Symmetrical clutch allows full torque in both pedalling directions, making it compatible with coaster brakes and fixed gear bikes without a rear brake.

Optional Easy-Shift plates cover the whole arm, making in possible to shift by pushing on a larger area, best for clip-less pedals.
