Description

The Cube Reaction Hybrid Race 800 is an electric mountain bike designed for riders who want to tackle varied terrain — forest tracks, gravel paths, and technical singletracks — without compromising on performance. The Bosch Performance CX Gen 5 motor produces up to 120 Nm of torque, meaning steep gradients and demanding trail sections become far more manageable, even at the end of a long ride.

The Bosch PowerTube 800 Wh battery is fully integrated into the Superlite aluminium frame, keeping the bike's profile clean and its centre of gravity low for better handling. Ride data is displayed clearly on the Bosch Purion 200 display, keeping key information at a glance without distraction.

The Fox 34 Float AWL fork provides 120 mm of travel (100 mm on size S with 27.5" wheels) and features a 2-position Sweep-Adjust RAIL damper so you can switch between an open, active setting and a firmer one depending on the terrain. Stopping power comes from Shimano XT BR-M8120 hydraulic disc brakes with 203 mm rotors front and rear — consistent and strong whether you're descending a muddy slope or navigating a busy bike path.

The 12-speed Shimano XT drivetrain (RD-M8200-SGS ShadowPlus rear derailleur, SL-M8210-IR shifter, Deore 10-51T cassette) shifts cleanly and quietly under load. ACID SLX 30 Tubeless Ready wheels paired with 2.6" Schwalbe Smart Sam tyres provide traction and confidence on loose or uneven ground. Available in S to XL with a trapeze frame design for easy step-over access.

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 Purion 200

The main thing, without distraction. The Bosch Purion 200 is the control screen designed for cyclists who want to keep their eyes on the road. Compact and integrated directly into the handlebars, it combines control and display in a single unit — clean, readable and perfectly within reach. Its clear display shows essential information at a glance: assistance level, speed, remaining autonomy and battery status. No frills, no extras — just what you need to ride with confidence. Robust and weather-resistant, it faithfully accompanies every outing, whatever the weather.
