Description

The Cube Reaction Hybrid Pro 800 FE is a hardtail e-MTB built for riders who want real off-road performance without giving up everyday usability. The Superlite aluminium frame, shaped using Gravity Casting technology, keeps things manageable at 27.5 kg for a fully-equipped electric mountain bike.

Power comes from the Bosch Performance Line CX motor, delivering 120 Nm of torque — enough to tackle steep climbs and muddy tracks with genuine ease. The Bosch PowerTube 800 Wh battery sits neatly inside the down tube, keeping the bike's balance and look clean. A Bosch Purion 200 display on the handlebar lets you switch assistance modes at a glance and pairs with the eBike Flow app for route and energy tracking.

The Shimano XT ShadowPlus 12-speed rear derailleur paired with a 10-51T cassette gives you the range to spin up technical climbs and push hard on the flat. The air suspension fork offers 120 mm of travel (100 mm in size S) to smooth out roots, rocks and rough paths, while Shimano BR-MT420 hydraulic disc brakes with 203/203 mm rotors keep stopping power predictable regardless of weather.

FE stands for Fully Equipped: ACID mudguards, a semi-integrated rear rack, battery-powered front and rear lights, and a kickstand are all fitted as standard. Whether you're heading into the woods on Saturday or commuting on Monday, the Reaction Hybrid Pro 800 FE is ready without any extra purchases.

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 XT RD-M8100-SGS, ShadowPlus, 12-Speed

The trail reference. The Shimano XT RD-M8100-SGS rear derailleur is the culmination of decades of Shimano expertise applied to the most demanding terrain. Robust, precise and remarkably quiet, it stands out as the natural choice for riders who make no compromise on the quality of their transmission. ShadowPlus technology reduces chain oscillation on bumpy terrain thanks to an adjustable friction system on the tread — less noise, less chain skipping, more concentration on riding. The SGS (Super Extra Long) version offers the maximum yoke capacity to absorb the entire development range of the widest 12-speed cassettes, up to 51 teeth.

Shimano Deore CS-M6100, 10-51T

The transmission that opens all horizons. The Shimano Deore CS-M6100 cassette in 10-51T is the versatile reference for cyclists who want to cover as much ground as possible without ever being caught off guard. With an exceptionally wide development range - from the small chainring for the steepest climbs to the large one for full-speed descents - it adapts to all terrain profiles and all levels of practice. Designed for Shimano Deore 12-speed transmissions, it combines lightness, shifting precision and proven durability. The profiled teeth and optimized shift ramps guarantee smooth and quiet gear changes, even under load – a quality usually found on much higher-end groupsets.

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.
