Now available with the latest Bosch 2.0 update - delivering up to 120 Nm of torque
Cube Stereo Hybrid One77 HPC SLT 800 2027
Full Power. Total Control.
The Cube Stereo Hybrid ONE77 HPC SLT 800 is the flagship model in Cube’s full-power electric enduro range. Its lightweight High Performance Composite frame combines 170mm of front and rear suspension travel with a mixed-wheel configuration, creating a stable and highly capable platform for technical climbs, rough descents and demanding days in the hills.
A race-focused Bosch Performance Line CX-R motor and integrated 800Wh PowerTube battery provide substantial power and range. Fox Factory suspension, SRAM XX Eagle AXS Transmission, Magura Race Pro brakes and a premium Newmen Phase wheelset complete a specification designed for riders seeking top-level electric mountain bike performance.
Bosch Performance Line CX Gen 5
The Bosch Performance Line CX-R is the race-focused version of Bosch’s full-power electric mountain bike motor. Delivering up to 120Nm of torque, 750 watts of peak power and support of up to 600%, it provides rapid acceleration and the assistance required for steep, technical climbs.
Its Race mode delivers support more quickly and extends assistance briefly after the rider stops pedalling. This can help maintain momentum over rocks, roots and stepped trail features where a complete pedal rotation may not be possible.
The motor’s sensitive response helps the rider manage its considerable output when traction is limited. Compatible assistance modes and motor characteristics can also be personalised through the Bosch eBike Flow app.

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 profile 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 CX-R 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, creating an uncluttered cockpit while protecting the screen from impacts. It clearly presents essential information including speed, battery charge, assistance mode, estimated range and ride data.
A compact Bosch Mini Remote allows assistance modes and display screens to be controlled without taking a hand away from the handlebar. As part of the Bosch Smart System, the display also connects with the eBike Flow app for ride recording, system updates and personalisation of compatible settings.

Fox Factory Suspension
A 170mm Fox 38 Float Factory fork uses the GRIP X2 damper to provide extensive high-speed and low-speed compression and rebound adjustment. This allows its performance to be tuned precisely for the rider, terrain and preferred handling characteristics.
The stiff 38mm chassis maintains steering accuracy through rough trail sections, steep terrain and hard compressions. Kashima-coated upper tubes help reduce friction, contributing to a smooth and responsive suspension action.
The fork is paired with a Fox Float X2 Factory rear shock, creating a balanced 170mm suspension platform. Its high-volume air spring and advanced damping provide sensitivity over smaller trail chatter alongside the support and control required for larger impacts, repeated hits and faster descents.
SRAM XX Eagle AXS Transmission
SRAM XX Eagle AXS Transmission provides fast and precise electronic 12-speed shifting without a conventional mechanical gear cable. Its robust full-mount construction is designed to handle demanding enduro riding and the increased drivetrain loads produced by a full-power electric mountain bike.
A wide-range 10-52T cassette supplies an extremely low climbing gear for steep gradients while retaining efficient ratios for faster trail sections. Electronic controls create a clean cockpit and deliver consistent gear changes throughout the ride.
The drivetrain is paired with a Race Face ERA E-MTB crankset and 36-tooth chainring. Its premium carbon construction helps reduce weight while providing the strength required for technical terrain and high-torque motor assistance.
Magura Race Pro Brakes
Magura Race Pro hydraulic disc brakes provide the powerful and controlled stopping performance required for steep descents and technical enduro riding. Strong braking force is combined with usable modulation, helping the rider manage speed accurately as grip and trail conditions change.
Their performance is particularly well suited to the increased speed and weight of a full-power electric mountain bike, providing dependable braking across longer and more demanding descents.
