Introducing a top-of-the-line full-suspension E-MTB built from the ground up for long days on the trails and maximum confidence in every turn.

It’s the ideal choice for demanding riders who love all-day mountain expeditions, exploring new trails, and demand uncompromising support from their bike on steep climbs.

Shimano EP600 – 85 Nm

Powerful electric assistance is provided by the proven Shimano STePS DU-EP600 mid-drive motor, which generates an outstanding 85 Nm of torque. This drive system delivers tremendous power to your legs on every climb, while maintaining a completely natural feel at a more relaxed pace. A reliable and uninterrupted power supply is provided by the fully integrated Darfon battery with a capacity of 630 Wh.

All key riding parameters are clearly displayed on the Shimano SC-EM800 color screen, which features Bluetooth technology for pairing with a smart device.

DVO Suspension and Trail Advanced Geometry

Total dominance on challenging terrain is guaranteed by a rigid 6061-T6 aluminum alloy frame that utilizes sophisticated Trail Advanced geometry. Premium air suspension from the American brand DVO absorbs harsh impacts from roots and rocks. Up front is a robust DVO Diamond E3 fork with a generous 150 mm of travel, while the rear is controlled by a top-of-the-line DVO Topaz T3Air shock with 140 mm of travel, mounted via a floating pivot system (Floating Pivot Suspension). As a result, the bike remains absolutely smooth, stable, and perfectly predictable even at high speeds.

microSHIFT shifting and Shimano brakes

To maintain an optimal cadence even on the steepest sections, the bike is equipped with a reliable 10-speed microSHIFT Advent X drivetrain. The cassette, with an incredible 11–48-tooth range, provides plenty of gears for tough climbs and quick transitions. Safe and powerful stopping with plenty of braking power to spare is handled by the high-performance Shimano M6120 four-piston hydraulic brakes, which clamp down on 180mm rotors on both the front and rear wheels.

29" wheels and a dropper seatpost

Perfect traction and quick rollover of obstacles are ensured by large 29-inch wheels with sturdy WTB STi 30 rims. These are fitted with aggressive WTB Trail Boss TCS Light/Fast Rolling tires , a generous 2.4 inches wide , that bite down uncompromisingly on any terrain. The One1 dropper post, with 125 mm of travel and a comfortable WTB Volt saddle, ensures perfect riding ergonomics and freedom of movement on descents. The upgraded cockpit is complemented by 760 mm-wide handlebars with Velo ERGO anatomical grips for a secure and firm grip.

This high-performance full-suspension e-bike is the perfect machine for more experienced riders who want to push their limits far beyond the boundaries of ordinary trails. Its greatest strength lies in the fantastic combination of a powerful Japanese motor with elite suspension and modern geometry. It’s the ultimate tool for all-day aggressive riding, allowing you to enjoy every meter of climb and the genuine adrenaline rush of steep, technical descents.
