Cube Stereo Hybrid ONE77 HPC SLX 800 Blackline Electric Mountain Bike
The Cube Stereo Hybrid ONE77 HPC SLX 800 Blackline is a premium high-performance electric enduro mountain bike designed for aggressive trail riders who demand maximum power, control and durability. Built with Cube’s advanced HPC carbon front triangle and aluminium rear triangle, this e-MTB delivers the perfect blend of stiffness, strength and responsive handling for extreme off-road terrain.
Powered by the latest Bosch Performance Line CX motor, delivering up to 85Nm of torque, the ONE77 HPC SLX 800 Blackline provides exceptional climbing power and smooth, natural pedal assistance on steep, technical and demanding trails. The integrated Bosch PowerTube 800Wh battery offers extended range, making it ideal for long enduro rides, mountain adventures and all-day trail exploration.
Engineered for downhill control and enduro performance, the bike features a Fox 38 Float suspension fork paired with a Fox Float X rear shock, delivering 170mm of travel front and rear. This advanced suspension setup ensures maximum traction, stability and comfort on rough, rocky and high-speed descents.
The Shimano XT 12-speed drivetrain provides precise, reliable shifting across all terrains, while powerful Shimano XT hydraulic disc brakes deliver consistent stopping performance in wet, muddy and steep conditions. Combined with a mullet wheel setup (29” front / 27.5” rear), the bike offers improved agility, cornering control and downhill confidence.
Finished in the striking Blackline design, the ONE77 HPC SLX 800 stands out with a sleek, stealth-inspired aesthetic while maintaining Cube’s proven Agile Trail Geometry for responsive handling and superior rider control.

| Previous model reviewed. Absolutely love the One77. Stable, aggressive, and insanely confidence-inspiring on descents, yet climbs better than expected. Powerful motor, great range, and bombproof components. A true no-compromise e-enduro beast. | |||||
