New Cube Stereo Hybrid One77 AT 800 2026 - Action Team
Full Power. No Limits.
Big mountain terrain demands an emtb that can rise to the challenge, and the Cube Stereo ONE77 HPC AT is built to do exactly that. With 170mm of travel front and rear and a mullet wheel setup – 29in up front for roll-over confidence and 27.5in at the rear for agility – this full-suspension electric mountain bike is engineered for riders who push hard on demanding trails and long alpine descents.
The carbon main frame is not only light and stiff but also refined in its detail. Integrated Cable Routing keeps the lines clean, while an angle-adjustable headset allows you to fine-tune handling to your riding style and terrain. A UDH dropout adds future-proof durability, and a Direct Mount chain guide ensures reliability when the trails turn rough. While Bosch ABS adds an extra layer of braking confidence and safety on steep, technical descents or slippery terrain.
At its core lies Bosch’s fourth-generation Performance CX drive unit, paired with an 800Wh PowerTube battery neatly housed in the down tube. The result is seamless, intuitive power delivery with the range to keep you riding further and exploring higher.
Bosch Kiox 400c display
Kiox 400C is the perfect display for the trail. Inconspicuously integrated in the frame and also full of functions. Securely installed in the top tube and therefore ideally protected from bumps and knocks.
Big travel. Bosch power. Trail ready.

Stereo Hybrid ONE77 AT - in depth
The Stereo Hybrid ONE77 HPC AT is built with big mountains in mind. To that end, we fitted Fox's Float 38 Factory fork and Float X2 Factory shock – because when you're making full use of 170mm of travel, you need to know you're in good hands. Shimano's XT Di2 1x12 gears select with uncanny electronic precision, getting your power to the trail with help from Bosch's CX drive, the 800Wh PowerTube battery, a Kiox 400C top tube-mounted display and an ACID carbon crank. We added a remote dropper seatpost for extra confidence and manoeuvrability on tough trails, while Shimano XT hydraulic disc brakes with ABS Pro ensure you can safely keep your speed in check. And Newmen Beskar 30 wheels – in mullet configuration – with Schwalbe 2.5in Magic Mary and Albert tyres – keep you rolling, whatever obstacles lie in your path.
