Description

The Cube Reaction Hybrid Race 800 is a hardtail e-MTB built for riders who want real trail performance without compromise. The Superlite aluminium frame uses Agile Ride Geometry to balance agility and stability, whether you're threading a singletrack or powering up a forest climb.

The Bosch Performance CX Gen 5 motor (120 Nm) is one of the most capable trail motors available, offering strong, smooth assistance that feels natural under your pedals. The Bosch PowerTube 800 Wh battery sits integrated inside the frame, keeping the weight low and central, while the Bosch Purion 200 display keeps assist level and remaining range in view.

Up front, the Fox 34 Float AWL fork with 2-position RAIL Damper (120 mm, e-bike optimised) handles trail chatter and bigger hits with ease. The Shimano XT BR-M8120 hydraulic disc brakes with 203 mm rotors front and rear give you confident, modulated stopping in wet or dry conditions. The Shimano XT 12-speed drivetrain (RD-M8200-SGS ShadowPlus derailleur, SL-M8210-IR Single Click shifter, Deore 10-51T cassette) rounds out a genuinely trail-capable build.

Available in sizes S through XXL — the S frame runs 27.5" wheels, while M to XXL use 29" wheels. ACID SLX 30 rims are Tubeless Ready and fitted with Schwalbe Smart Sam 2.6" tyres, for those who want to run lower pressures and improve grip further. A CUBE dropper seatpost is included as standard, a feature that genuinely changes how you ride on mixed terrain.

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.
