E:LEONARDO GEN3.ZEHUS 1/2.SPD/BELT/Ti SMART E:BIKE

The E:LEONARDO is a next-generation titanium smart e-bike engineered to deliver electric performance without compromising the purity of a traditional ride. Built around a lightweight, corrosion-resistant titanium frame, it combines refined road handling with long-term durability and natural vibration damping, resulting in a smooth, composed ride across urban and mixed terrain.

At its core is the Zehus Gen3 “All-in-One” hub, an advanced system that integrates motor, battery, and sensors entirely within the rear wheel. This fully self-contained architecture eliminates external wiring and bulky components, preserving a clean, cable-free aesthetic while delivering seamless pedal assistance up to 25 km/h. The system’s integrated KERS (kinetic energy recovery) captures braking and back-pedalling energy, extending range through intelligent regeneration.

Paired with a Gates Carbon Drive belt for silent, grease-free operation and available with optional internal two-speed gearing, the E:LEONARDO delivers a minimalist drivetrain with maximum versatility. Designed and assembled to order in London, it remains highly configurable while retaining a core philosophy: low maintenance, high efficiency, and a riding experience that feels intuitive, responsive, and mechanically elegant.

Improved charging, torque and new 200Wh battery.

Only adds a total of ~3kg.

Already compliant with the new EU stringent safety 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.
