Description

The Cube Reaction Hybrid Race 800 is an electric mountain bike built for riders who take their trail riding seriously. The Bosch Performance CX Gen 5 motor (120 Nm), part of the Bosch Smart System ecosystem, provides responsive and natural-feeling assistance whether you're grinding up a steep climb or pushing through a technical section. The Bosch PowerTube 800 Wh battery sits fully integrated within the frame to keep weight centred and the silhouette clean.

The Superlite aluminium frame uses Gravity Casting Technology to reinforce stress points without adding unnecessary weight, while the Agile Ride Geometry keeps handling predictable and confidence-inspiring on varied terrain. The Fox 34 Float AWL fork with 120 mm of travel is specifically tuned for e-bikes, handling the added mass and torque that come with electric assistance. ACID SLX 30 Tubeless Ready rims paired with 2.6-inch Schwalbe Smart Sam tyres deliver grip and comfort on loose, rocky, or mixed ground.

Gear changes are handled by the Shimano Deore XT 12-speed groupset (RD-M8200-SGS ShadowPlus derailleur, SL-M8210-IR shifter, Deore 10-51T cassette), which shifts quietly and reliably even in muddy conditions. Braking power comes from Shimano XT BR-M8120 hydraulic disc brakes with 203 mm rotors front and rear — enough stopping force for fast descents with a loaded e-MTB. A CUBE dropper seatpost comes fitted as standard, making it easy to adapt your riding position without stopping mid-trail.

Available in sizes S through XXL — with 27.5" wheels on size S and 29" from M upward — the Reaction Hybrid Race 800 in snow'n'black is a well-specced, trail-ready package that doesn't require immediate upgrades out of the box.

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.
