The Gen3 Smart Wheel All-in-One is a fully integrated rear-hub e-bike conversion system that transforms a standard bicycle into a refined, intelligent electric ride, without compromising its original character. Developed byZehus, the system consolidates motor, battery, controller, and sensors into a single compact rear hub, eliminating external wiring, frame modifications, and bulky add-ons.
Designed for seamless integration, the Smart Wheel preserves the clean aesthetics and handling of a traditional bike while delivering smooth pedal assistance up to 25 km/h. Its advanced torque and cadence sensing ensures that power delivery feels natural and responsive, enhancing rather than overpowering the riding experience.
At the core of the system is Zehus’ proprietary KERS (kinetic energy recovery system), which captures energy during braking and back-pedalling to recharge the battery on the move.
Installation is straightforward, requiring only a rear wheel swap and minimal setup, making it an ideal solution for riders seeking a discreet, low-maintenance upgrade. The result is a lightweight, self-contained e-drive system that delivers smart energy management, silent operation, and a clean, cable-free finish, bringing modern electric capability to virtually any compatible bicycle.
