Description

The Cube Stereo Hybrid ONE77 HPC SLX 800 is a full-suspension electric mountain bike aimed at riders who want genuine trail capability without compromise. The front triangle is built from Cube's C:62 monocoque carbon (Advanced Twin Mold Technology), paired with a 6061-T6 aluminium rear triangle and the Efficient Trail Control FSP 4-Link suspension platform. Total weight comes in at 24.7 kg — competitive for an e-MTB with this level of specification.

Power comes from the Bosch Performance Line CX motor (100 Nm), part of the Bosch Smart System ecosystem and managed via the Kiox 400C display mounted on the top tube. The 800 Wh PowerTube battery sits flush inside the carbon downtube, keeping the centre of gravity low and the silhouette clean.

Suspension is handled by a Fox 38 Float Rhythm GRIP fork (170 mm, e-bike optimised, 15x110 mm Boost) and a Fox Float X Performance rear shock (230x65 mm) with two-position lever for adjustable low-speed compression — allowing riders to switch between an efficient pedalling platform and a more active descending setting. The Mullet configuration — 29" up front, 27.5" at the rear — helps the bike track confidently at speed while staying nimble through tight switchbacks.

A Shimano XT 12-speed drivetrain with a 10-51T cassette covers a wide range of gradients, while Shimano XT BR-M8220 hydraulic disc brakes (203/203 mm) provide reliable modulation on long descents. Continental Argotal 29" (front) and Kryptotal Rear 27.5" (rear) tyres, both Tubeless Ready, round out a trail-focused build designed to perform on loose and demanding terrain.

Bosch Gen 5 'Performance CX' - 120 Nm

The benchmark engine for riders who make no compromises. The 5th generation Bosch Performance Line CX is the trail engine par excellence: with 120 Nm of torque and assistance up to 25 km/h, it delivers raw and controlled power, capable of swallowing the most demanding slopes without ever flagging. Redesigned from the ground up, this 5th generation engine is more compact and lighter than its predecessors, while improving responsiveness. The response to pedaling is immediate and precise, with intelligent torque management that adapts to each variation in terrain - technical trails, steep climbs or chaotic paths, the CX knows no limit.

Bosch PowerTube 800 Wh

Uncompromising autonomy. The Bosch PowerTube 800 Wh is the battery that frees cyclists from the constraint of mileage. With 800 Wh of capacity, it pushes the limits of every outing — whether it's a long commute, a weekend getaway or a multi-day wilderness adventure. Integrated directly into the frame tube, the PowerTube disappears into the silhouette of the bike for a clean aesthetic and optimal protection against shocks and bad weather. Light for its capacity, it recharges quickly and pairs perfectly with all Bosch Smart System motors for intelligent energy management in real time.

Bosch Kiox 400C

The trail screen that disappears into the frame. The Bosch Kiox 400C is Bosch's new benchmark for demanding e-MTBs — a connected and intelligent display, integrated directly into the upper tube of the frame, perfectly protected from shocks and impacts even on the fastest descents. Its 2-inch color screen displays information with an exceptional brightness of 1,000 cd/m², readable in all conditions, and an ambient light sensor automatically adjusts the brightness.

Shimano XT RD-M8100-SGS, ShadowPlus, 12-Speed

The trail reference. The Shimano XT RD-M8100-SGS rear derailleur is the culmination of decades of Shimano expertise applied to the most demanding terrain. Robust, precise and remarkably quiet, it stands out as the natural choice for riders who make no compromise on the quality of their transmission. ShadowPlus technology reduces chain oscillation on bumpy terrain thanks to an adjustable friction system on the tread — less noise, less chain skipping, more concentration on riding. The SGS (Super Extra Long) version offers the maximum yoke capacity to absorb the entire development range of the widest 12-speed cassettes, up to 51 teeth.

Fox 38 Float Rhythm GRIP, Tapered, 15x110mm, E-Bike Optimized, 170mm

Heavy artillery for the VTTAE. The Fox 38 Float Rhythm GRIP changes category - with a 38mm lower tube and 170mm of travel, we're definitely leaving the trail to enter the territory of enduro and gravity. A massive, solid fork designed to withstand the most violent impacts without ever bending, even under the weight and increased constraints of an electric bike.

Fox Float X Performance, 230x65mm, Adjustable LSR w/ 2-Pos. Lever

The shock absorber that sees the bigger picture. The Fox Float X Performance in 230x65mm is the extended stroke version of the Float Compared to the 230x60mm, the 65mm stroke allows the frame to develop more travel and more progressive kinematics, to swallow the most violent impacts with disconcerting serenity.

Shimano Deore CS-M6100, 10-51T

The transmission that opens all horizons. The Shimano Deore CS-M6100 cassette in 10-51T is the versatile reference for cyclists who want to cover as much ground as possible without ever being caught off guard. With an exceptionally wide development range - from the small chainring for the steepest climbs to the large one for full-speed descents - it adapts to all terrain profiles and all levels of practice. Designed for Shimano Deore 12-speed transmissions, it combines lightness, shifting precision and proven durability. The profiled teeth and optimized shift ramps guarantee smooth and quiet gear changes, even under load – a quality usually found on much higher-end groupsets.

Shimano XT BR-M8220, Hydr. Disc Brake (203/203)

Maximum power, on both sides. The Shimano A configuration designed for riders who make no compromise on braking power and fade resistance. An evolution of the BR-M8120, the BR-M8220 benefits from Shimano's latest advances in 4-piston hydraulic braking — immediate bite, precise modulation and absolutely consistent performance from the first to the last turn, whether in dry weather, rain or mud. Servo-Wave technology guarantees rapid and progressive engagement from the first press of the lever, for total control in all circumstances.
