Description

The Cube Reaction Hybrid Pro 800 is a hardtail e-MTB built for riders who want genuine off-road capability without the complexity of a full-suspension setup. At its heart sits the Bosch Performance CX Gen 5 motor, producing 120 Nm of torque — enough to take the sting out of steep climbs and rooty trail sections. The Bosch PowerTube 800 Wh battery sits neatly inside the frame, keeping the bike's handling balanced and the silhouette clean, while the Bosch Purion 200 display keeps assist level and range in view.

Shifting duties are handled by a Shimano XT RD-M8200-SGS rear derailleur — one of Shimano's most reliable trail-grade components — paired with a Shimano Deore 10-51T cassette across 12 speeds. That wide gear range means you'll rarely be caught without the right ratio, whether you're grinding up a fire road or spinning along a flat forest track. The RockShox Recon Silver RL Air fork provides 120 mm of travel (100 mm on the size S / 27.5" build) to smooth out the bumps and keep the front wheel in contact with the ground.

Stopping power comes from Shimano BR-MT420 hydraulic disc brakes with 203 mm rotors front and rear — consistent bite in wet or muddy conditions. The CUBE Dropper Post (31.6 mm, internal cable routing) makes it easy to drop the saddle on the fly so you can attack descents with confidence, then raise it back up for climbs. ACID SLX 30 Tubeless Ready rims laced to Schwalbe Smart Sam 2.6" tyres round out a versatile package that handles gravel tracks, singletrail and forest paths with equal ease.

Available in sizes S through XXL — with 27.5" wheels on size S and 29" wheels from M upwards — the Reaction Hybrid Pro 800 fits a wide range of riders and riding styles.

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.

Shimano BR-MT420, Hydr. Disc Brake (203/203)

Braking power where it actually matters: on a heavy, loaded bike, heading downhill. The Shimano BR-MT420 is a four-piston hydraulic disc brake caliper, fitted here with 203 mm rotors front and rear — the largest size in Shimano's mountain bike range. Four pistons instead of two means a larger pad surface and better-distributed pressure: around 20% more power than the two-piston version, and above all power that doesn't fade after three corners. On an electric mountain bike weighing 25 kg before the rider even gets on, that is not a luxury. The aluminium alloy body sheds heat, and the mineral oil circuit keeps a consistent bite point in the rain, in mud, or after a long descent. The D03S resin pads supplied as standard deliver progressive, quiet braking; they can be swapped for metallic D02S pads for greater heat resistance and better wet-weather performance — both share the same shape. The post-mount fitting is standard, so servicing can be done by any bike shop and spare parts are available everywhere.
