Description

The Cube Reaction Hybrid SLT 800 is a hardtail e-MTB built for demanding off-road riding. The Bosch PowerTube 800 Wh battery is fully integrated into the Superlite aluminium frame, keeping the bike's centre of gravity low and its lines clean. When extra range is needed, the bike is compatible with the Bosch PowerMore range extender, adding up to 250 Wh more capacity.

Power comes from the Bosch Performance CX Gen 5 motor — 120 Nm of torque that can be fine-tuned through the eBike Flow app to match your riding style or local trail regulations. Paired with the Shimano XT Di2 12-speed electronic shifting system, gear changes are immediate and consistently accurate, even when climbing hard. With no derailleur cables, there's less to maintain and less to go wrong on longer trips.

Braking is handled by Shimano XT BR-M8120 4-piston hydraulic disc brakes (203/203 mm), with Bosch eBike ABS on the front wheel preventing wheel lock-up — a real-world safety benefit when descending or riding on slippery surfaces. Up front, the Fox 36 Float AWL fork offers 120 mm of travel with a 2-position RAIL damper, so you can switch between a supple trail setting and a stiffer climbing mode without stopping to adjust anything manually.

The bike is available in sizes S through XXL. Note that size S comes with a Fox 34 Float AWL fork (100 mm, 27.5" wheels) rather than the 29" setup of the larger sizes. Navigation and ride data are displayed on the Bosch Kiox 500 screen, mounted cleanly on the bar.

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.
