Electrify your ride. Keep your bicycle’s soul.
The definitive all-in-one electric conversion, hand-built in London.
Upgrade your bicycle to a sophisticated electric machine without the visual clutter of traditional conversion kits. The GEN3.ZEHUS Smart Rear Wheel conceals a complete electric powertrain within a single, elegant rear hub. There are no external batteries to bolt on, no unsightly wires to tape down, and no cumbersome sensors to calibrate. It is simply a wheel, reinvented.
Designed for the discerning cyclist who values aesthetics as much as performance, this Gen 3 system preserves the natural handling and classic lines of your bike while delivering smooth, intelligent assistance up to 25 km/h. Whether you require a gentle nudge on the morning commute or a robust push up a steep incline, the system adapts intuitively to your riding style.
The "Invisible" E-Bike Upgrade
At the heart of the wheel lies the Zehus Gen 3 All-in-One hub. Weighing a mere 3 kg (approx.), it houses the 250W motor, battery, and electronics in a sealed, weather-resistant unit. Installation is refreshingly straightforward: simply swap your current rear wheel for the conversion wheel, tighten the nuts, and ride.
Wireless Simplicity: The system is entirely self-contained. It connects via Bluetooth to your smartphone (or optional remote) for customisable ride modes, system locking, and diagnostics.
Kinetic Energy Recovery System (KERS): Borrowing technology from Formula 1, the hub captures energy when you back-pedal or brake, feeding power back into the battery to extend your range.
Each wheel is hand-built to order using premium rims and spokes, ensuring a build quality that matches the sophistication of the motor.
