Description

The Cube Reaction Hybrid SLX 800 is an electric mountain bike aimed at riders who want a capable, well-specified machine for trail riding without unnecessary weight or compromise. The aluminium frame houses a fully integrated Bosch PowerTube 800 Wh battery — keeping the silhouette clean while delivering serious range on longer rides.

Power comes from the Bosch Performance CX Gen 5 motor (85 Nm), part of the Bosch Smart System ecosystem. It reads your pedalling input and responds smoothly, whether you're grinding up a steep fire road or navigating a rooty singletrack.

The component spec is solid throughout. A Fox 34 Float AWL fork with 2-position adjustment handles trail chatter — open for rough terrain, locked for climbing or smooth surfaces. Shimano XT BR-M8120 hydraulic disc brakes with 203 mm rotors front and rear give you progressive, powerful stopping in all conditions. The Shimano XT 12-speed drivetrain with a 10-51T cassette ensures you always have the right gear, even on the steepest pitches.

Ride data is managed through the Bosch Kiox 300 display, which keeps key metrics visible without distraction. Available in sizes S through XL, rolling on 29" wheels for confident handling on varied terrain.

Bosch Gen 5 'Performance CX' - 85 Nm

The benchmark engine for riders who make no compromises. The 5th generation Bosch Performance Line CX is the trail engine par excellence: with 100 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 300

Information, without compromise. The Bosch Kiox 300 is the connected screen that strikes the right balance between readability, compactness and functionality. Mounted on the handlebars, it displays all the essential data of your ride on a clear and readable backlit screen - even in direct sunlight - without cluttering the cockpit. Connected to the eBike Flow app via Bluetooth, it provides access to software updates, personalization of riding modes and detailed monitoring of your performance. Easy to use, it is aimed at both urban cyclists and demanding hikers who want to keep an eye on their data without complicating their lives.
