Description

The Cube Reaction Hybrid SLX 800 FE is a versatile hardtail e-MTB designed for riders who move between off-road trails and everyday use without switching bikes. The Superlite aluminium frame — built with Gravity Casting Technology — cleanly integrates the Bosch PowerTube 800 Wh battery, keeping weight centred and the overall profile tidy.

At the heart of the bike is the Bosch Performance Line CX (Gen 5) motor, producing 120 Nm of torque. In practical terms, that translates to strong, natural-feeling assistance whether you're tackling steep singletrack, loaded panniers on a daily commute, or soft ground after rain. Assistance modes and battery status are managed through the Bosch Kiox 500 display, which is easy to read at a glance.

Shifting is handled by Shimano XT Di2 (RD-M8260-SGS, 12-speed electronic system), activated via a Shimano Deore Di2 remote lever. Electronic shifting means no cables to stretch or adjust — gear changes stay precise for the lifetime of the drivetrain. The Fox 34 Float AWL fork (120 mm, e-bike optimised) smooths out trail irregularities, while Shimano XT BR-M8120 4-piston hydraulic disc brakes provide controlled, fade-resistant stopping with 203 mm rotors front and rear.

The FE (Full Equipment) designation means the bike ships with mudguards, a rear rack, kickstand and integrated lighting — accessories that would otherwise require separate investment. Newmen Performance 30 wheels (29") are Tubeless Ready, paired with Schwalbe Smart Sam 2.6" tyres for balanced grip and rolling efficiency. A remote dropper seatpost rounds out a build that's genuinely ready for varied riding from day one.

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 Kiox 500

The screen for those who want to see everything. The Bosch Kiox 500 is the advanced version of the Kiox range — a larger, brighter and more comprehensive connected display, designed for cyclists who want to access all of their riding data without taking out their smartphone. Its enlarged display offers optimal readability in all conditions, whether in the middle of the forest or in full urban sunshine. Permanently connected to the eBike Flow app via Bluetooth, it centralizes navigation, performance data and customization of modes in one place. A clear interface, careful ergonomics and exemplary responsiveness - the Kiox 500 is the reference screen for long and demanding outings.

Shimano XT Di2 RD-M8260-SGS, 12-Speed, Electronic Shifting System

Electronic shifting conquers the trail. The Shimano A simple press of the button is enough for an instantaneous, silent and perfectly calibrated gear change, even in the middle of a recovery or on a chaotic section. The SGS (Super Extra Long) version offers the maximum screed capacity to cover the entire development range of the widest 12-speed cassettes. No more loose cables, no more misadjustments during outputs - the Di2 maintains absolute precision from the first to the last hour, without intervention. And thanks to Bosch eShift compatibility, it integrates natively into the Bosch VAE ecosystem for automatic gear changes based on cadence and terrain.
