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

The E:LEONARDO Gen 3 represents a definitive step forward in the design of the lightweight titanium smart e-bike. Engineered for the discerning urban rider, this bicycle eschews the visual bulk of traditional electric systems in favour of a fully integrated, cable-free aesthetic.

At its core lies the Zehus Gen 3 all-in-one hub, a self-contained unit housing the motor, battery, and sensors within the rear wheel. This proprietary technology allows the E:LEONARDO to maintain the clean lines and handling characteristics of a standard pedal cycle while providing intelligent electric assistance.

Paired with a maintenance-free Gates Carbon Drive belt and a corrosion-resistant titanium frame, this machine is built for longevity and silent operation in all weather conditions. Whether configured as a single-speed or with the optional 2-speed transmission, the E:LEONARDO delivers a composed, efficient, and responsive ride.

Aerospace-grade 3Al-2.5V Titanium for superior damping and durability.

Gates Carbon Drive CDX Belt (Grease-free and silent).

Available in Single Speed or 2-Speed internal gearing configurations.

Fully programmable via the dedicated Zehus smartphone application for custom power modes and remote locking.

Significantly lighter than conventional e-bikes, ensuring easy manoeuvrability.

GEN3 ZEHUS ALL-IN-ONE.

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

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.

ZEHUS HORIZON BIKE+ MODES (NOT ON HALOS):

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

Unconventional e-bike system to let you ride beyond limits.

It features an automatic energy recovery system, similar to hybrid cars, working in addition to a slope and road quality sensor, to optimise your pedalling effort.

HORIZON features advanced sensors to optimise the assistance, helping you accelerate when climbing hills, then automatically recover energy on the flatter or downhill terrain.

Through the smart and automatic energy optimisation of BIKE+ modes, it is possible to significantly extend the range capabilities of the e-bike, delivering power when necessary and recovering energy to recharge the battery accordingly.

Customise your riding experience by adjusting the motor parameters.

HORIZON is the first and only pedal-assisted e-bike system that doesn’t need to be recharged. It allows you to ride in an assist level where you will never have to recharge the battery from an electrical outlet.

Together with the back-pedalling brake-regen, in BIKE+ mode, HORIZON intelligently recovers energy from your forward pedalling too, when your effort is low and slope/road-quality sensors allow it, never completely depleting the battery and always keeping some power in reserve for the uphill sections.

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.
