Now available with the latest Bosch 2.0 update - delivering up to 120 Nm of torque
Cube Stereo Hybrid One77 HPC SLX 800 2027
Full Power. Total Control.
The Cube Stereo Hybrid ONE77 HPC SLX 800 is a long-travel electric mountain bike designed for enduro riding, technical descents and demanding days in the hills. Its High Performance Composite frame combines 170mm of front and rear suspension travel with a mixed-wheel configuration, creating a stable and confidence-inspiring platform for steep, rough and fast terrain.
A Bosch Performance Line CX motor and integrated 800Wh PowerTube battery provide the power and capacity needed for sustained climbing and longer adventures. Fox Performance suspension, Shimano XT components and a reinforced Newmen wheelset give the SLX model a capable specification designed for serious off-road riding.
Bosch Performance Line CX Gen 5
The latest Bosch Performance Line CX motor delivers up to 120Nm of torque, 750 watts of peak power and support of up to 600%. Its substantial output provides the assistance needed to tackle steep gradients and technical climbs, while responsive power delivery helps maintain traction across loose, rocky and root-covered surfaces.
Eco mode prioritises efficiency, Tour+ automatically adapts assistance as conditions change, and eMTB mode provides progressive support for technical off-road riding. Turbo delivers the strongest assistance for demanding climbs and rapid acceleration.
Compatible motor characteristics can be personalised through the Bosch eBike Flow app. Riders can prioritise maximum support for steep climbing or reduce the output to create a more natural ride feel and conserve battery capacity.

Removable 800Wh Battery
An integrated Bosch PowerTube 800Wh battery provides the capacity needed for longer rides, sustained climbing and repeated enduro laps. Its position within the down tube maintains the bike’s clean appearance while helping to keep weight central within the frame.
Actual range will depend on assistance mode, elevation, terrain, rider weight and riding conditions. The large 800Wh capacity allows the rider to use the motor’s stronger assistance modes more frequently without needing to conserve power throughout the entire ride.

Bosch Kiox 400C Display
The Bosch Kiox 400C colour display is integrated directly into the top tube, keeping the cockpit uncluttered while placing essential information in a protected and easy-to-view position. It clearly displays data including speed, battery charge, assistance mode, estimated range and ride information.
A compact Bosch Mini Remote allows the rider to change assistance modes and navigate the display without taking a hand away from the handlebar. As part of the Bosch Smart System, the Kiox 400C connects with the eBike Flow app for ride recording, system updates and personalisation of compatible motor and display settings

Fox Performance Suspension
A 170mm Fox 38 Float Performance fork uses the GRIP damper to provide the stiffness, support and controlled suspension performance required for aggressive enduro riding. Its substantial 38mm chassis helps maintain accurate steering through rough terrain, hard compressions and steep technical sections.
The fork is paired with a Fox Float X Performance rear shock, creating a balanced 170mm suspension platform. Together, the two units help maintain traction over roots and rocks while providing the support and composure required for larger impacts, repeated trail features and faster descents.
The adjustable air springs allow the suspension to be set for the rider’s weight and preferences, while the damping controls make it possible to balance sensitivity, support and stability.
Shimano XT Drivetrain
Shimano XT 1x12-speed gearing uses a wide-range 10-51T cassette, providing the low ratios needed for steep technical climbs alongside efficient gearing for faster trail sections. Its single-chainring configuration keeps operation straightforward while delivering the range required for varied enduro terrain.
The drivetrain is paired with an ACID MTB Hybrid Pro crankset, Newmen Pin and 36-tooth chainring. The slightly larger chainring complements the motor’s strong assistance while retaining suitable climbing range through the 51-tooth cassette.
Shimano XT Brakes
Shimano XT BR-M8220 four-piston hydraulic disc brakes provide the powerful and controlled stopping performance required for a long-travel electric mountain bike. Their substantial braking force helps manage speed on steep descents, while usable modulation allows the rider to make precise adjustments as grip and trail conditions change.
The brakes are particularly well suited to the increased speed and weight of a full-power enduro eMTB, providing dependable performance across longer and more demanding descents.
Newmen Wheels and Mullet Configuration
The Newmen Performance 30 Base/Strong wheelset combines a responsive front wheel with a reinforced rear construction designed to manage increased motor, drivetrain and impact loads.
A 29-inch front wheel improves rollover and stability across rough terrain, while the smaller 27.5-inch rear wheel helps the bike remain agile and provides additional clearance on steep descents. This mixed-wheel configuration balances high-speed composure with responsive handling.
