Cube Stereo Hybrid One77 HPC Race 800 2027
Full Power. Total Control.
The Cube Stereo Hybrid ONE77 HPC Race 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 delivers 170mm of suspension travel at both ends, 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. RockShox suspension, SRAM Eagle 90 Transmission and Magura Louise brakes complete a dependable specification built around aggressive off-road riding.
Bosch Performance Line CX Gen 5
The Bosch Performance Line CX drive unit delivers up to 120Nm of torque, providing powerful support for steep climbs and technical terrain. Its responsive power delivery adapts to changing gradients and rider input, helping maintain momentum and traction without making the bike feel difficult to control. Through the Bosch eBike Flow app, riders can customise assistance modes and access additional ride information.

Removable 800Wh Battery
The motor is paired with a high-capacity Bosch PowerTube 800Wh battery, giving the Stereo Hybrid ONE77 HPC Race 800 the capacity required for longer trail rides and bigger days in the hills. Its integration within the down tube maintains a clean frame profile while helping to keep the additional weight positioned centrally and low within the bike.

Cube Stereo Hybrid One77 HPC Race 800 2027 - IN DEPTH
A 170mm RockShox Domain Gold air fork provides the stiffness and controlled suspension performance required for long-travel electric mountain bike riding. Its substantial chassis helps maintain steering accuracy through rocks, roots and hard compressions, while the adjustable air spring allows it to be set for the rider’s weight.
The fork is paired with a RockShox Super Deluxe Select rear shock, creating a balanced 170mm suspension platform. Together, the two units help the bike maintain grip across rough terrain while providing the support and composure needed for larger impacts, steep descents and repeated trail features.
SRAM Eagle 90 Transmission provides precise and durable mechanical 12-speed shifting. Its robust full-mount construction is designed to handle demanding off-road use and the increased drivetrain loads generated by a full-power electric mountain bike.
A wide-range 10-52T cassette provides an extremely low climbing gear for steep gradients while retaining efficient ratios for faster sections. The drivetrain is paired with an ACID MTB Hybrid Pro crankset, Newmen Pin and 36-tooth chainring.
Magura Louise hydraulic disc brakes provide the powerful stopping performance needed to control a long-travel electric mountain bike. Their strong braking force helps manage speed on steep descents, while usable modulation allows controlled adjustments as grip and trail conditions change.
The brakes are paired with an ACID SLX 30 wheelset, creating a durable setup suited to rough terrain and the higher loads produced by the motor, battery and aggressive riding.
