The mountains demand versatility – a bike that conquers climbs with the same confidence it descends. The Stereo Hybrid One77 HPC SLX masters this delicate balance through intelligent engineering, Cube's advanced carbon frame technology, and a meticulously curated component selection that excels across all terrain. This is a serious mountain machine built for riders who refuse to compromise, ready to elevate your alpine adventures to new heights.
Powering your journey is Bosch's groundbreaking 2025 Gen 5 Performance Line CX Smart System – the culmination of a decade of e-MTB innovation. This fifth-generation drive unit represents a significant evolution with its lighter magnesium housing (shedding 100 grams from the previous version) and sophisticated sensor array that responds with remarkable precision to your pedal inputs. The result is an astonishingly natural riding experience where power delivery feels intuitive rather than artificial, allowing you to navigate technical climbs with unprecedented control and fluidity.
The motor's refined engineering extends to its acoustics as well. When descending, the external drivetrain components (chain, cassette, chainring) decouple from the internal drivetrain (gearbox, motor), dramatically reducing mechanical noise on the trail. This quieter operation enhances your connection with the natural environment and maintains the stealth factor that seasoned mountain bikers appreciate.
Cube has paired this cutting-edge motor with Bosch's remarkable PowerTube 800Wh battery, boasting the highest energy density in its class while weighing an impressive 400 grams less than the previous 750Wh version. This power reserve integrates seamlessly into the carbon downtube, providing substantial range for epic all-day adventures without range anxiety. For those seeking truly unlimited exploration, the optional bottle-sized PowerMore 250Wh range extender can boost your total battery capacity to an extraordinary 1050Wh – available
Matching this power is a suspension system ready for serious mountain terrain. The Fox 38 Float Rhythm fork features robust 38mm stanchions and delivers 170mm of travel with a 2-position sweep-adjust GRIP damper, specially optimised for e-MTB applications. Working in harmony with the rear Fox Float X Performance shock (also offering 170mm travel), this suspension package effectively neutralises challenging terrain while maintaining excellent sensitivity and control. The adjustable low-speed rebound and two-position compression lever allow for quick trail adaptations without tools.
Transferring power efficiently through the drivetrain, Shimano's renowned XT 12-speed groupset provides crisp, decisive shifting even under load. The XT rear derailleur with ShadowPlus technology minimises chain slap and potential drops, while the direct-attach shifter delivers instant gear changes with minimal effort. The wide-range Shimano Deore 10-51T cassette offers both climbing-friendly gears for steep ascents and speed-oriented ratios for fast descents.
The Stereo Hybrid One77 employs Cube's proven "mullet" wheel configuration – a 29 inch front wheel for improved rollover capability paired with a more agile 27.5 inch rear wheel. This thoughtful combination provides the best of both worlds: stability and momentum conservation up front with enhanced manoeuvrability and clearance at the rear. The Newmen Performance 30 wheelset strikes an excellent balance between strength and weight, while the tubeless-ready design allows for lower tyre pressures and improved traction.
Schwalbe's aggressive Magic Mary front tyre with Addix Soft compound delivers outstanding grip in loose and technical terrain, while the matching Tacky Chan rear tyre with its robust Super Gravity casing provides dependable traction and impressive puncture resistance. When it's time to slow down, Shimano's powerful XT four-piston hydraulic disc brakes deliver authoritative stopping power with excellent modulation through their 203mm rotors front and rear.
The sophisticated frame platform combines a C:62 carbon front triangle using Advanced Twin Mold Technology with a durable aluminium rear triangle. Cube's Efficient Trail Control suspension design maintains pedalling efficiency without sacrificing small-bump sensitivity, while the Agile Trail Geometry creates a balanced riding position for both climbing and descending. Thoughtful details abound: the angle-adjustable headset allows personalised handling characteristics, integrated cable routing enhances aesthetics while reducing maintenance, and the Universal Derailleur Hanger provides future-proof compatibility.
Completing this trail-ready package, the Cube Dropper Post offers instant saddle height adjustment via a handlebar-mounted lever, allowing quick transitions between climbing and descending positions. Dressed in its clean Desert Stone & Black livery, the Stereo Hybrid One77 HPC SLX makes a subtle yet authoritative statement on the trail – a serious mountain bike for riders with serious ambitions.
