Description

The Cube Reaction Hybrid SLX 800 is a hardtail e-MTB designed for riders who want to tackle a wide variety of trails without sacrificing reliability or component quality. The Superlite aluminium frame fully integrates the Bosch PowerTube 800 Wh battery into the downtube, keeping the bike's silhouette clean and its centre of gravity low. Compatible with Bosch PowerMore, it can accept up to 250 Wh of additional capacity for longer, more demanding rides.

The Bosch Performance Line CX Gen 5 motor provides smooth, powerful assistance that feels natural on climbs and mixed terrain. The Bosch Kiox 500 display gives you clear access to navigation and assistance data, while the Bosch LED Controller lets you switch between assist modes directly from the handlebar.

The Shimano XT Di2 12-speed electronic drivetrain eliminates cable stretch and adjustment entirely — gear shifts are sharp and consistent every time. The 10-51T cassette covers a wide range suited to everything from steep climbs to fast descents. Shimano XT BR-M8120 4-piston hydraulic brakes with 203 mm rotors deliver confident, progressive braking even in wet or muddy conditions.

The Fox 34 Float AWL fork with its 2-position RAIL damper and 120 mm of travel is optimised for e-bike use, absorbing trail chatter and bigger hits alike. The frame also includes mounts for mudguards, a rack and a kickstand, making this bike just as capable on the commute as on the trail. Available in sizes S to XXL, each finished in a hand-applied Artline paint.

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 500

The screen for those who want to see everything. The Bosch Kiox 500 is the advanced version of the Kiox range — a larger, brighter and more comprehensive connected display, designed for cyclists who want to access all of their riding data without taking out their smartphone. Its enlarged display offers optimal readability in all conditions, whether in the middle of the forest or in full urban sunshine. Permanently connected to the eBike Flow app via Bluetooth, it centralizes navigation, performance data and customization of modes in one place. A clear interface, careful ergonomics and exemplary responsiveness - the Kiox 500 is the reference screen for long and demanding outings.

Shimano XT Di2 RD-M8260-SGS, 12-Speed, Electronic Shifting System

Electronic shifting conquers the trail. The Shimano A simple press of the button is enough for an instantaneous, silent and perfectly calibrated gear change, even in the middle of a recovery or on a chaotic section. The SGS (Super Extra Long) version offers the maximum screed capacity to cover the entire development range of the widest 12-speed cassettes. No more loose cables, no more misadjustments during outputs - the Di2 maintains absolute precision from the first to the last hour, without intervention. And thanks to Bosch eShift compatibility, it integrates natively into the Bosch VAE ecosystem for automatic gear changes based on cadence and terrain.
