Description

The Cube Reaction Hybrid SLX 800 is a high-spec electric mountain bike built for riders who want reliable performance on mixed terrain without cutting corners on components. The Bosch Performance Line CX (Gen 5) motor provides strong, responsive assistance, while the frame-integrated Bosch PowerTube 800 Wh battery gives you the range to tackle long rides — and the system is PowerMore-ready, meaning you can add up to 250 Wh extra when you need even more autonomy.

Shifting duties are handled by the Shimano XT Di2 electronic 12-speed drivetrain. Unlike a mechanical system, electronic shifting means the derailleur always moves to the right gear instantly, regardless of load or trail conditions. Suspension comes from a Fox 34 Float AWL fork with a 2-position RAIL Damper, letting you lock out for climbs or open up for technical sections — all without stopping. Braking is provided by Shimano XT BR-M8120 4-piston hydraulic disc brakes, a reliable choice for steep or technical terrain.

Newmen Performance 30 wheels fitted with Schwalbe Smart Sam 2.6" tyres deliver traction and confidence on a wide range of trail surfaces. The remote dropper post lets you adjust saddle height on the fly — a feature that genuinely changes how you ride on mixed terrain. Everything is monitored through the Bosch Kiox 500 display, compact and easy to read on the move.

Available in platinum'n'reflex in sizes S, M, L and XL, the Reaction Hybrid SLX 800 is a serious trail tool for riders who want top-tier components and day-to-day reliability in one package.

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.

Fox 34 Float AWL, 2-Position Sweep-Adjust RAIL Damper, Tapered, 15x110mm, E-Bike Optimized, 100mm

The fork designed for city and road e-bikes. The Fox 34 Float AWL with RAIL Damper 2-position Sweep-Adjust shock absorber is a fork specially designed to meet the particular requirements of electric bicycles — higher mass, high torques, intensive use. With 100mm of travel, it is optimized for electric trekking bikes, electric gravel bikes and assisted urban bikes, where comfort and control take precedence over pure trail performance. The RAIL Damper system with 2-position Sweep-Adjust allows you to easily switch between a soft open position for uneven paths and a firmer position for smooth roads — a quick, intuitive adjustment that maximizes pedaling efficiency. The E-Bike Optimized designation means that the fork has been reinforced and recalibrated to support the additional weight and specific constraints of everyday e-bikes.
