Description

The Cube Reaction Hybrid Race 800 is an electric hardtail mountain bike built around an easy-entry frame — lower standover height for confident, effortless mounting — and kitted out with trail-ready components for tackling a wide range of terrain.

The Bosch Performance CX (Gen 5, 120 Nm) motor provides strong, smooth assistance that scales well to steep gradients and technical sections. The Bosch PowerTube 800 Wh battery sits fully integrated within the frame, keeping the centre of gravity low and the silhouette clean.

Up front, the Fox 34 Float AWL fork (100 mm travel, e-bike optimised) handles trail impacts with composure, while the Shimano XT 12-speed groupset (RD-M8200-SGS ShadowPlus derailleur, SL-M8210-IR shifter, Deore 10-51T cassette) delivers smooth, reliable shifts under load. Braking is handled by Shimano XT BR-M8120 hydraulic disc brakes with 203 mm rotors front and rear — enough stopping power for confident descents. ACID SLX 30 Tubeless Ready rims in 27.5" and 2.6" Schwalbe Smart Sam tyres round out a capable and well-balanced package.

A CUBE dropper post and the Bosch Purion 200 display complete the setup, giving you effortless saddle height adjustment and clear ride data at a glance. Available in sizes S to XL in a snow'n'black finish.

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.

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.
