The Bosch "Gen 5" Performance CX motor launched as a 85Nm motor. Bosch periodically release updates for their drive systems, normally for reliability and performance. Recently, Bosch announced the option for an extra 35Nm of torque.
This bike will come with the latest update of 120Nm torque output already installed. This update unlocks up to 600% maximum assistance in Turbo mode. You can adjust the power back down if required by using the Bosch eBike Flow App.
The new eMTB+ riding mode delivers dynamic support at the highest level, blending the smooth control of eMTB mode with the full power of Race mode - offering up to 600% maximum support. It's available as part of this new firmware update.
Extended boost remains easy to modulate like in eMTB mode, while unleashing the full force of Race mode when needed. Up to 750 watts of power is delivered naturally and responsively, based on your pedal input. eMTB+ gives you the best of both worlds - combining agility, performance, and control for a truly natural riding experience. It is also possible to maintain peak power for longer, depending on riding conditions.
Features
The Cube Stereo Hybrid ONE77 HPC SLX 800 2027 is a long-travel e-enduro rig crafted for high-speed alpine descents and technical bike park lines. Featuring an ultra-stiff C:62® monocoque carbon front triangle, it balances rugged stability with sharp, agile handling over brutal terrain.
Designed for aggressive enduro racers, freeriders, and gravity specialists, this 170mm full-suspension machine packs the structural strength, motor torque, and long battery range required to self-shuttle massive peaks and charge steep, rock-strewn downhill trails with total rider authority.
Suspension duties are executed by a heavy-duty Fox air combination tuned specifically for aggressive long-travel enduro riding. Up front, the Fox 38 Float Performance GRIP fork provides 170mm of ultra-plush, e-bike optimised travel with beefy 38mm stanchions and a 15x110mm Boost axle for pin-point steering precision through brutal rock gardens.
At the rear, the matching Fox Float X Performance shock offers external rebound adjustment and a two-position lever, delivering supple small-bump traction and progressive bottom-out resistance over severe jump landings.
Brakes & Gears
Anchor-grade stopping capability comes from high-end Shimano XT BR-M8220 four-piston hydraulic disc brakes operating on 200mm rotors front and rear. Renowned for incredible modulation, heat dissipation, and immediate lever bite, this setup ensures fade-free consistency on long, steep mountain descents.
Whether dropping into sheer technical chutes or scrubbing speed ahead of sharp berms, riders experience supreme lever feedback, relentless clamping strength, and complete stopping confidence across wet, muddy, and loose off-road conditions on every single run.
Drivetrain duties are handled by a complete Shimano XT 12-speed group, featuring a wide-range 10-51T XT cassette and CN-M8100 chain. Driven by a direct-attach XT single-click shifter, the XT ShadowPlus rear derailleur delivers instantaneous, surgical gear shifts even under heavy motor torque.
This broad gear spread ensures you always maintain an optimal pedalling cadence, whether self-shuttling up steep fire road ascents or putting down maximum power along fast, undulating downhill singletrack sections on your mountain adventures.
Shimano XT four-piston hydraulic disc brakes with dual 200mm rotors deliver instantaneous, fade-free stopping power, precise lever feedback, and total anchor control down steep, technical, high-speed mountain singletrack descents.
The Shimano XT 12-speed ShadowPlus rear derailleur delivers fast, surgical gear changes. Its integrated chain stabiliser prevents slap, ensuring silent, smooth power transfer across rough root sections and technical descents.
The Shimano XT 12-speed single-click shifter features direct-attach mounting, delivering crisp, instantaneous gear changes while effectively preventing double-shifting under heavy motor torque to preserve premium drivetrain components.
Wheels & Tyres
The Newmen Performance 30 wheelset features a reinforced, tubeless-ready design engineered specifically to withstand aggressive enduro thrashing. Built with Boost hub spacing (15x110mm front, 12x148mm rear), these rims offer outstanding lateral stiffness and direct power transfer under heavy motor loads.
The 30mm internal width supports high-volume tyres effortlessly, allowing lower inflation pressures for maximum off-road traction, improved trail compliance, and reduced rolling resistance over rough, technical ground on demanding mountain rides.
Continental Argotal Enduro Soft 29x2.4-inch front and Kryptotal Downhill Soft 27.5x2.4-inch rear tyres deliver exceptional cornering bite and puncture protection across varied terrain.
The aggressive tread blocks dig deep into loose dirt, thick mud, and wet rock, while the mixed wheel layout maximises front-end grip and rear-end manoeuvrability. This tubeless-ready setup provides outstanding durability, low rolling resistance, and predictable handling when pushing hard on high-speed downhill lines.
The bottom line..
This long-travel e-MTB is tailored for aggressive gravity enthusiasts and enduro specialists who demand maximum suspension capability alongside long-range climbing endurance.
It caters perfectly to bike park riders and alpine explorers seeking a lightweight carbon full-suspension bike equipped with full Shimano XT componentry and ultra-powerful brakes. With 170mm of plush Fox 38 travel and sticky Continental rubber, it empowers riders to push their technical boundaries and master extreme downhill routes.
Cube and Bosch set the industry standard for value by combining advanced C:62 carbon frame engineering with world-class motor technology at a competitive price point.
Cube's rigorous manufacturing ensures long-term frame durability, while Bosch delivers unmatched drive unit reliability, diagnostic simplicity, and an extensive global dealer support network. Together, they provide riders with a future-proof, high-performance electric mountain bike backed by readily available spare parts, effortless servicing, and long-term riding satisfaction on every trail.
