Description

The Cube Reaction Hybrid SLT 800 is a high-end hardtail e-MTB engineered for riders who want performance and sophistication on demanding trails. The Superlite aluminium frame, shaped using Gravity Casting Technology, houses the Bosch PowerTube 800 Wh battery in a fully integrated fashion — keeping the bike's silhouette clean and its handling balanced. Wheel size adapts to rider size: 27.5" for size S, 29" for M through XXL.

The Bosch Performance CX Gen 5 motor produces 85 Nm of torque with a natural, responsive feel that makes climbs less daunting without over-assisting on flat sections. The Bosch Kiox 500 display sits cleanly on the bar and shows speed, battery level and navigation data at a glance, so your attention stays on the trail ahead.

The Sram X0 Eagle AXS wireless drivetrain removes derailleur cables entirely from the equation: shifts are crisp and instantaneous even under pedalling load, and the 10-52T cassette covers everything from steep climbing to fast flat sprints. Up front, the Fox 34 Float AWL fork offers 120 mm of travel (100 mm in 27.5") with a two-position damper that lets you stiffen up for climbs and open up for descents. Magura Gustav PRO 4-piston hydraulic disc brakes at both ends provide consistent stopping power in any conditions.

Newmen Performance 30 tubeless-ready wheels and Schwalbe Smart Sam 2.6" tyres round out a well-considered build that's ready to handle variable terrain straight out of the box. The frame is also PowerMore-ready, meaning a +250 Wh range extender battery can be added for even longer adventures.

Bosch Gen 5 'Performance CX' - 85 Nm

The benchmark engine for riders who make no compromises. The 5th generation Bosch Performance Line CX is the trail engine par excellence: with 100 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.
