• The E‑NERA GEN3 Zehus Smart E‑Bike reimagines urban mobility with a seamless blend of minimalist design and cutting‑edge e‑bike technology. At its core is the latest GEN3 Zehus Halos All‑In‑One drive system, integrating the 250 W motor, 200 Wh battery and control electronics into a single ultra‑compact rear hub unit under just ~3 kg. This fully enclosed solution eliminates bulky external batteries, wiring harnesses and sensors, giving you a clean aesthetic, intuitive ride feel and simplified long‑term maintenance.
• Whether you’re commuting through dense city streets or enjoying a weekend ride, the E‑NERA delivers smooth pedal assistance up to 25 km/h with fluid power delivery and minimal drag when the motor is off. Its standout feature, a motorsport‑inspired Kinetic Energy Recovery System (KERS), lets you recapture energy through a simple back‑pedal motion during slowing or braking, effectively extending your range without complexity.
• Built to last in our London workshop, the E‑NERA’s steel frame and quality aluminium components prioritise durability and ease of service. Thoughtfully routed external cables, sealed bearings and user‑friendly mounting points for mudguards or a rear rack further enhance everyday practicality. And because the system is fully integrated, you can ride it like a conventional bicycle whenever you choose, giving you flexibility without compromise.

• Precision‑engineered drivetrain solution designed for riders who demand both simplicity and performance. At its heart lies an ultra‑thin (just 10 mm) planetary gearbox that neatly integrates with your chainring, with no bulky mechanisms, no extra cables or derailleurs.
• Shifting is ingeniously simple: a gentle heel tap on the side button lets you engage the alternative ratio, either a 1 : 1.65 overdrive in the Speed‑Drive version for higher speeds.
• Built with premium materials and designed to take full torque in both pedalling directions, it’s equally compatible with fixed‑gear and coaster‑brake setups. This compact, low‑maintenance gearbox gives you a minimalist look with maximised versatility.
• Change gear with a simple kick of the heel on the side buttons, while standing still or under heavy load.
• Low maintenance.
• No cables, levers or derailleurs.
• High efficiency, high quality materials, ensure great longevity.
• Symmetrical clutch allows full torque in both pedalling directions, for coaster brakes and fixed-gear bikes without a rear brake.
• The optional EASY-SHIFT plates, available on request, cover the whole crank arms and allow for shifting by pushing on a larger area, best for clip-in pedals.
• SPEED-DRIVE ratios: 1x direct-drive and 1.65x overdrive.
• 1st gear perfectly matches the motor's speed range for max power, agility and acceleration. Use second gear to relax cadence at the motor's top speed or to go even faster on pedal power
