Cube Stereo Hybrid One44 HPC SLX 800 2027
The Perfect All-rounder. Powerful & Precise.
The Cube Stereo Hybrid ONE44 HPC SLX 800 is a full-power electric mountain bike designed for technical trail riding, demanding climbs and longer off-road adventures. Its lightweight High Performance Carbon frame (carbon front / aluminium rear triangle) combines 150mm of front suspension with 140mm of rear travel, delivering a balanced blend of control, agility and stability across varied terrain.
Bosch Performance Line CX Gen 5
At the heart of the Cube Stereo Hybrid ONE44 HPC SLX 800 is the latest Bosch Performance Line CX motor. Delivering up to 120Nm of torque, 750 watts of peak power and support of up to 600%, it provides the assistance needed to tackle steep climbs, technical trail features and demanding off-road terrain.
Despite its impressive output, the Bosch CX motor delivers its power in a smooth and controlled way. Its responsive assistance adapts naturally to the rider’s input, helping maintain grip on loose or uneven surfaces while still providing strong acceleration when required. Paired with the integrated 800Wh Bosch PowerTube battery, it creates a powerful and efficient system for longer trail rides and all-day mountain bike adventures.

Bosch Kiox 400C Display
The Bosch Kiox 400C colour display is integrated directly into the top tube, keeping the cockpit clean while placing important ride information in a protected and easy-to-view position. The screen can display information including speed, remaining battery charge, assistance mode, estimated range and ride data.
A compact Bosch Mini Remote allows the rider to change assistance modes and move between display screens without removing a hand from the handlebar. As part of the Bosch Smart System, the Kiox 400C also connects to the eBike Flow app for ride recording, system updates and personalisation of compatible motor and display settings.

Cube Hybrid ONE44 HPC SLX 800 2027 - IN DEPTH
Shimano XT 1x12-speed gearing uses a wide-range 10-51T cassette, providing the low ratios required for steep climbs alongside efficient gearing for faster trail sections. Its single-chainring configuration keeps operation straightforward while delivering the range needed for varied mountain bike terrain.
Shimano XT BR-M8220 four-piston hydraulic disc brakes provide powerful and controlled stopping performance. Their increased braking force is well suited to the additional speed and weight of a full-power electric mountain bike, helping the rider manage speed confidently on steep descents and technical trails.
