Description

The Cube Reaction Hybrid SLT 800 is a full-capability electric mountain bike built for riders who take their trails seriously. The Bosch Performance CX Gen 5 motor provides strong, natural-feeling assistance, housed within a Superlite aluminium frame that fully integrates the battery — keeping the bike looking clean and riding balanced.

The Bosch PowerTube 800 Wh battery handles long days on the trail without anxiety about range. And if you need even more, the PowerMore compatible system allows you to add up to 250 Wh of extra capacity. Navigation and assist management happen through the Bosch Kiox 500 display, mounted cleanly at the bar.

The Shimano XT Di2 electronic drivetrain takes the guesswork out of shifting: 12 precisely indexed gears change automatically and accurately, even when you're pushing hard on a climb. Stopping power comes from Shimano XT BR-M8120 hydraulic disc brakes with front ABS (203/203 mm), which prevent front wheel lock-up on loose or wet terrain — a tangible safety benefit on technical descents.

Up front, the Fox 36 Float AWL fork (120 mm travel on 29" builds) absorbs trail chatter and features a 2-position sweep-adjust damper so you can firm it up for climbs and open it back up for the descent. Newmen Performance 30 Tubeless Ready wheels and Schwalbe Smart Sam 2.6" tyres round out a bike that's genuinely trail-ready from the box.

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.
