Description

The Cube Reaction Hybrid Pro 800 FE is a fully equipped hardtail electric mountain bike for riders who want one bike that does everything: trails and forest tracks at the weekend, daily commuting the rest of the week. Its Superlite aluminium frame, built with Gravity Casting Technology, fully integrates the battery and routes the cables internally for clean lines and easier maintenance.

The Bosch Performance Line CX motor (up to 120 Nm) delivers smooth, perfectly metered assistance, equally at home accelerating away from city lights and grinding up technical climbs. The Bosch PowerTube 800 Wh battery is hidden inside the down tube for generous range — and the bike is PowerMore compatible, letting you add up to 250 Wh of extra capacity. Everything is controlled from the compact, easy-to-read Bosch Purion 200 display.

On the component side, the Shimano XT RD-M8200-SGS ShadowPlus 12-speed drivetrain paired with a Deore 10-51T cassette covers a very wide gear range and stays precise in mud and grit. The RockShox Recon Silver RL Air fork provides 120 mm of travel (100 mm on the 27.5" size), the Shimano BR-MT420 hydraulic disc brakes with 203 mm rotors front and rear stop confidently even when loaded, and ACID SLX 30 tubeless-ready wheels on Schwalbe Smart Sam 2.6" tyres deliver grip on every surface.

Delivered Fully Equipped, nothing is missing to ride from day one: mudguards, ACID Carrier SIC 2.0 rear rack, integrated X-Connect front and rear lighting, kickstand and bell. The CUBE Dropper Post, operated by a handlebar lever, lets you adjust your riding position without stopping. Thanks to the Size Split system, size S rolls on 27.5" wheels while M, L and XL run 29", for geometry matched to every rider.

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-M8200-SGS, 12-Speed

The new-generation XT, built to take a hit. The Shimano Deore XT RD-M8200-SGS is the mechanical 12-speed rear derailleur of the redesigned XT groupset: the same shifting precision Shimano puts in its top tier, in an architecture designed from the outset for impacts, mud and the torque of an electric motor. Its headline change is Shadow ES — a slimmer, stronger evolution of the Shadow system, with a wider link structure that keeps the chain settled over rough ground. The body uses a wedge-shaped profile designed to move out of the way and absorb the blow when the derailleur catches a root or a rock, instead of bending. The pulleys and cage are shielded to stop trail debris from jamming the rotation — a detail that matters once winter riding starts. In SGS (long cage) form it takes 12-speed Hyperglide+ cassettes up to 51 teeth, for a 510% gear range: enough to climb a steep ramp fully loaded and still accelerate on the flat without gaps in the progression. It is explicitly approved for e-bikes and pedelecs with assistance up to 25 km/h, which many mountain bike derailleurs are not.

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.
