Cube Stereo Hybrid One44 HPC SLX 800 Electric Mountain Bike 2027

A serious trail eMTB with a distinctive presence, the Cube Stereo Hybrid ONE44 HPC SLX 800 Dream Black combines high-performance trail capability with a finish that stands apart from more conventional mountain bike colourways. Despite the name, Dream Black presents predominantly as a rich aqua-blue, giving the bike a cleaner, more contemporary character without detracting from its purposeful design.

At its heart is Cube’s lightweight High Performance Carbon frame, combining 150mm of front suspension with 140mm of rear-wheel travel to create a bike that feels composed on technical descents, assured through rough ground and efficient when the trail turns upwards. Cube’s adjustable headset also allows the geometry to be fine-tuned to suit your riding style and terrain.

Power comes from the latest Bosch Performance Line CX drive system, paired with a fully integrated 800Wh PowerTube battery. The CX motor delivers smooth, responsive assistance with the strength to make sustained and technical climbs significantly more manageable, while the high-capacity battery gives the ONE44 the range for long trail days and bigger mountain rides.

Crucially, the rest of the specification is capable of making full use of that performance.

A 150mm Fox 36 Performance fork is paired with a Fox Float Performance rear shock, giving the bike the support and control needed for fast, rough and unpredictable trails. Continental Kryptotal 2.4in tyres on Newmen Performance 30 wheels provide dependable grip and a reassuringly planted feel when cornering, braking or negotiating loose surfaces.

The drivetrain and braking package is equally accomplished. Shimano XT 1x12 gearing provides fast, precise shifting across a wide range of terrain, while Shimano XT four-piston hydraulic disc brakes with 200mm rotors deliver powerful, progressive braking when speeds increase or gradients steepen.

An integrated Bosch Kiox 400C display places key riding information neatly within the top tube, contributing to the bike’s particularly clean cockpit. Advanced internal cable routing, a Direct Mount chain guide and UDH-compatible dropout continue that attention to detail, while X-Connect compatibility allows a suitable ACID front light to connect directly to the bike. A remote dropper post is fitted as standard.

Built for demanding trail riding

The Stereo Hybrid ONE44 HPC SLX 800 sits in an appealing middle ground for experienced riders: substantial enough for genuinely challenging terrain, without becoming an unwieldy, gravity-focused machine.

Its 150/140mm suspension platform gives you the control to tackle rocky descents, roots, drops and fast trail-centre riding with confidence, while the carbon chassis, carefully considered geometry and Bosch drive system make it equally rewarding when covering distance or gaining height.

The result is not simply a powerful electric mountain bike. It is a well-balanced trail bike with a particularly strong supporting specification - one designed to make difficult terrain more accessible, extend the scope of your rides and leave you with more energy for the sections that matter.

The Dream Black finish gives this version an additional point of difference. Its aqua-blue appearance feels modern and distinctive without being ostentatious, complementing the clean carbon frame and integrated Bosch system particularly well.

For riders looking for a premium carbon eMTB capable of long days, technical climbs and serious descending - and who want something visually more distinctive than a conventional black finish - the Cube Stereo Hybrid ONE44 HPC SLX 800 Dream Black is an exceptionally complete package.
