Description

The Cube Reaction Hybrid Race 800 in polarlight'n'prism is a high-performance electric hardtail mountain bike, built for riders who want to explore varied trails, ride long distances and take on serious mountain terrain.

Power comes from the Bosch Performance Line CX motor, delivering up to 100 Nm of torque for raw, controlled assistance that swallows the steepest climbs without ever flagging, paired with an integrated Bosch PowerTube 800 Wh battery for genuine all-day range. The Bosch Purion 200 display keeps essential ride data within thumb's reach.

What sets this build apart is its SRAM Eagle 90 Transmission — the world's first mechanical groupset with a Full Mount design. The derailleur bolts directly to both sides of the frame around the rear axle, so there's no derailleur hanger to bend or break — a genuine advantage on an e-bike, where high torque and rough terrain punish traditional drivetrains. With no adjustment screws, a huge 520% range (10-52T) and X-Sync cassette mapping, it shifts precisely even under full power, mid-climb, and it's fully rebuildable.

Control comes from Magura Louise 4-piston hydraulic brakes with 203 mm rotors, delivering maximum stopping power in wet or muddy conditions, while a RockShox Recon Silver RL Air fork (120 mm) and grippy 2.6" Schwalbe Smart Sam tyres soak up the terrain and keep you planted.

Ideal for mountain bikers who want a powerful, robust and long-range e-hardtail for technical trails, long tours and mountain climbs.

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.
