The E-NERA is an approach to urban e-mobility, where functional design meets practical innovation. Built in our London workshop, each bike features the latest GEN3 Zehus All-in-One system, a fully integrated hub motor that houses the 250W motor, 200Wh battery, and control electronics in a single compact unit weighing just 3kg. This eliminates the external wiring, sensors, and battery packs typical of traditional e-bikes. The system provides smooth pedal assistance up to 25 km/h, but what distinguishes it is the kinetic energy recovery capability borrowed from motorsport technology. A simple back-pedal motion activates regenerative braking, capturing energy that would otherwise be lost and extending your range. The steel frame and aluminium components are chosen for their durability and ease of maintenance, while the clean external cable routing means repairs and upgrades remain straightforward. Whether you’re commuting across the city or exploring at leisure, the E-NERA offers versatility without compromising the feel of riding a proper bicycle. It can even be ridden as a conventional bike when desired, giving you options rather than dependencies.

Improved charging, torque and new 200Wh battery.

Only adds a total of ~3kg

Already compliant with the new EU safety stringent standards.

International network of repair and assistance centres.

The lightest, most compact, and super efficient direct-drive system to energise your bike, also featuring its unique KINETIC ENERGY RECOVERY SYSTEM (KERS).

It all works in unison.

The integrated motor, battery, and electronics work seamlessly to assist the cyclist while pedalling or recovering energy.

Activate the K.E.R.S. through back-pedalling to extend the range of your e-bike.

Use the ZEHUS wireless ecosystem to control the All In One while riding, or set it once and forget it. The motor offers extra functionalities when using the optional Controller, the Zehus App, or a third-party display.

Lock your motor from the app to enhance the security of the bike while parked.

The integrated Kinetic Energy Recovery System allows the motor to collect braking energy to recharge the batteries; it is activated manually, with a back-pedal movement, or from the controller.

OPTIONAL "SPEED-DRIVE" 2-SPEED INTERNAL-GEARBOX CRANK-SET

• • • • • • • • • • • • • • • • • • • • • •

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
