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 ONE44 HPC SLX 800 2027 represents a benchmark in carbon e-MTB trail engineering. Built around a stiff C:62® monocoque carbon frame with progressive geometry, it combines razor-sharp responsiveness with unwavering stability on high-speed technical terrain.
Designed for aggressive mountain bikers and backcountry explorers, this full-suspension machine provides the structural strength, range, and drive unit power required to conquer steep mountain passes, technical rock gardens, and demanding singletrack descents with complete rider authority across all trail conditions.
Suspension is managed by a premium Fox Performance air package tuned specifically for aggressive off-road riding. Up front, the Fox 36 Float Performance GRIP fork provides 150mm of plush, e-bike optimised travel with 36mm stanchions and a 15x110mm Boost axle for pin-point line precision.
At the rear, the matching Fox Float Performance shock delivers supple small-bump compliance and progressive bottom-out resistance, keeping the rear wheel glued to the dirt across root-covered trails, high-speed chatter, and harsh landing impacts.
Brakes & Gears
Stopping power is supplied by high-end Shimano XT BR-M8220 four-piston hydraulic disc brakes equipped with 200mm rotors front and rear. Renowned for supreme modulation and thermal management, this setup delivers immediate, fade-free braking power on long, steep alpine descents.
Whether hauling down steep technical chutes or feathering speed through tight singletrack turns, riders benefit from crisp lever feedback, incredible anchor strength, and absolute stopping confidence across wet, muddy, and unpredictable off-road trail conditions on every single ride.
Drivetrain duties are handled by a full 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 pedal loads.
This broad gear spread ensures you always maintain an optimal pedalling cadence, whether grinding up sheer vertical gradient ascents or putting down maximum power along fast, flowing downhill 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 trails.
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 strong base design built specifically to withstand aggressive trail riding. Utilising 28 spokes up front and 32 at the rear paired with Boost hub spacing (15x110mm front, 12x148mm rear), these tubeless-ready rims provide impressive lateral stiffness and efficient power transfer.
The 30mm internal width supports wide tyres perfectly, allowing lower pressures for maximum off-road traction, enhanced compliance, and reduced rolling resistance over rough, rocky trail surfaces.
Continental Kryptotal tyres in Enduro Soft front and Downhill Soft rear compounds deliver ultimate cornering grip and puncture protection across varied terrain. The aggressive tread blocks bite firmly into loose dirt, mud, and wet rock, while the soft rubber compounds maximize traction during heavy braking and sharp cornering manoeuvres.
This tubeless-ready combination offers exceptional durability, low rolling resistance, and predictable handling, giving riders absolute control when pushing hard on technical, high-speed singletrack lines.
The bottom line..
This high-spec e-MTB is tailored for serious mountain enthusiasts and aggressive trail riders who demand pro-level componentry and uncompromised range. It caters perfectly to endurance riders and alpine explorers seeking a lightweight carbon full-suspension bike capable of mastering steep technical climbs and demanding downhill descents alike.
With 150mm of plush Fox travel, full Shimano XT componentry, and robust Continental rubber, it empowers riders to push their technical limits and tackle big mountain loops with total confidence.
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.
Power
Powered by the high-performance Bosch CX Generation 5 drive unit, this e-MTB delivers a massive 120Nm of torque for effortless climbing across extreme gradients.
Paired with an integrated 800Wh Bosch PowerTube battery, the system provides an impressive power-assisted range of 30 to 170 miles. Cockpit control is managed by the ergonomic Bosch Mini Remote alongside the clear Kiox 400C colour display, displaying real-time speed, battery status, and assist modes on the fly.
The setup connects seamlessly to the Bosch eBike Flow app via Bluetooth, enabling riders to customize motor assistance curves, track detailed fitness metrics, perform wireless system software updates, and navigate trails with integrated GPS mapping for an upgraded, fully connected mountain biking experience.
The Bosch Kiox 400C display and Mini Remote combination provides a vibrant colour screen showing speed, battery range, and assist modes for effortless handlebar control and clear trail visibility.
The Bosch Performance Line CX Generation 5 motor delivers explosive 120Nm torque and 250W power output, providing smooth pedal assistance and exceptional climbing drive across steep, technical trail terrain.
The integrated 800Wh Bosch PowerTube battery delivers massive energy storage capacity, providing up to 170 miles of power-assisted range for long-distance mountain rides, alpine climbs, and demanding off-road exploration.
