The Cube Reaction Hybrid Pro 800 is built for riders who want a powerful e-MTB that can handle anything from city streets to technical trails. Its Aluminium Superlite frame uses Gravity Casting Technology for strength and clean integration, with internal cable routing and a fully integrated 800Wh battery. Cube’s Agile Ride Geometry keeps handling predictable and lively, whether you’re climbing steep terrain or descending rough trails.
Power comes from the Bosch Performance Line CX motor, delivering up to 100Nm of torque for smooth, responsive assistance. The 800Wh battery provides the range for big days out, and the bike is PowerMore-ready, so you can add an extra 250Wh range extender if you need even more distance. Cube’s X-Connect system also makes it easy to add accessories like an ACID front light.
Up front, a SR Suntour X1-32 LO-R Air fork with 120mm travel (100mm on smaller sizes) keeps things controlled and comfortable. The Shimano XT 12-speed drivetrain gives you crisp, precise shifting with a huge gear range for steep climbs and fast flats. Braking comes from Shimano MT420 4-piston hydraulic disc brakes with oversized 203mm rotors, ensuring confident stopping power in all conditions.
The bike rolls on ACID SLX 30 tubeless ready wheels fitted with Schwalbe Smart Sam 2.6in tyres, giving excellent grip and stability across different surfaces. A Cube dropper seatpost, controlled from the bars, adds confidence on descents and technical sections, while finishing kit like the ACID Sequence saddle and lock-on grips keep comfort dialled in.
With its blend of Bosch’s latest drive system, a large-capacity battery, and Cube’s proven e-MTB design, the Reaction Hybrid Pro 800 gives you the freedom to explore further, climb higher, and enjoy every part of the ride.
