Description

The Cube Reaction Hybrid SLT 800 is a 2025-2026 hardtail e-MTB built for riders who want to push further on trails without carrying the weight of a full-suspension bike. The Superlite aluminium frame uses Cube's Agile Ride Geometry and fully hides the Bosch PowerTube 800 Wh battery inside the downtube, keeping the silhouette clean and the centre of gravity low.

Power comes from the Bosch Performance Line CX Gen 5 motor, producing 85 Nm of torque. In practice, this means smooth and immediate support when you hit a steep section or loose ground — without the abrupt cut-off that cheaper systems can have. The Bosch Kiox 500 display gives you a clear read on battery level and assist mode at a glance. The bike is also PowerMore-ready, meaning you can attach an optional 250 Wh range extender for longer rides.

The SRAM X0 Eagle AXS 12-speed drivetrain eliminates cables entirely: gear changes are triggered electronically through the SRAM AXS Pod Controller. The 10-52T cassette covers a wide gear range, handling anything from steep technical climbs to fast open trails. Suspension duties are handled by the Fox 34 Float AWL with its 2-position RAIL damper — open for descents, locked for efficient pedalling on climbs.

Stopping is taken care of by Magura Gustav PRO 4-piston hydraulic disc brakes on both wheels, offering consistent braking performance in mud and rain. Newmen Performance 30 Tubeless Ready rims paired with Schwalbe Smart Sam 2.6" tyres round out a well-matched trail setup. The Cube Dropper Post (31.6 mm, internal routing) lets you drop the saddle quickly on descents without stopping.

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.
