Cube Stereo ONE77 Electric Bikes
The Cube Stereo ONE77 electric mountain bikes are the ultimate trail companions, combining rugged design with powerful performance and exceptional value.
The Cube Stereo ONE77 electric bikes jump well beyond a standard trail e-MTB — it’s built for big trails, big descents and big climbs. With a carbon (or high-spec alloy) frame built using Cube’s C:62 monocoque Advanced Twin Mold technology, it’s both stiff and light enough to stay agile when things get rough. Under the skin sits a Bosch Performance Line CX motor (latest generation) with up to 100 Nm of torque, paired to a Bosch PowerTube 800 Wh battery — that means climbs feel almost effortless, and the large battery gives you the kind of range and endurance needed for all-day epics or long multi-terrain rides.
Equipped with integrated Bosch electric assistance and sturdy carbon frames, these eBikes deliver impressive power and agility. Advanced suspension systems and precise handling make them adept at tackling steep climbs and technical descents with ease.
With customisable settings to suit various terrains and riding styles, they offer an exhilarating experience for seasoned trail riders. Built with premium components and long-lasting batteries, they ensure reliability and endurance on the toughest trails.
The Stereo ONE77 series represents Cube's dedication to innovation, offering a perfect mix of power, control, and durability for off-road adventures. On rough descents and technical terrain the ONE77 comes alive: long-travel suspension (170 mm fork, capable rear shock), aggressive tyre and wheel setup (usually mullet — larger front wheel + smaller rear), and geometry that leans toward stability and control rather than race-bike twitchiness. Brakes, drivetrain and suspension spec change by model, but even lower-end ONE77 variants give you a “ready-for-trails” package — while top-end builds bring in premium components (Fox suspension, powerful four-piston brakes, electronic drivetrain) that make this bike a serious enduro-ready e-MTB.

Yes — its long-travel suspension (typically a 170 mm fork and capable rear shock), mullet-style wheelset (big front, smaller rear), and stable geometry are designed for challenging descents, rock gardens, rooty trails and steep terrain.
The Cube Stereo ONE77 bikes are designed for advanced (or aspiring!) riders who crave challenging trails and technical terrain. Ideal for those who seek a powerful, agile ride, these bikes offer exceptional handling, robust design, and electric assistance, making them perfect for conquering steep climbs and thrilling descents with confidence. The specification to value in pound notes is what sets Cube apart from its competitors, offering the very best specification as some of the lowest prices.
It’s very versatile. Thanks to the powerful Bosch motor and large battery, the ONE77 climbs impressively well. But with aggressive suspension, tyres and geometry, it also handles technical descents reliably — making it a good all-rounder for enduro-style riding or mixed terrain.
The ONE77 typically uses a full-suspension setup with a 170 mm front fork (e.g. Fox 38 Float) and a capable rear shock (e.g. Fox Float X2 on higher-spec builds), paired with a C:62 carbon frame or high-spec alloy option — balancing stiffness, control, and weight.
Each model in the Cube Stereo ONE77 range uses the same frame, battery and motor - its the rest of the specification which changes. The brakes, gears and suspension increase in value (and often decrease in weight) as you move up through the models. The cheaper models offer specification suited to newer riders, while the specification of the models like the Stereo ONE 77 TM and ONE77 Action are aimed at more advanced riders and rougher terrain.
Yes — the big 800 Wh battery provides substantial range, and the full-suspension setup plus robust build quality make it suitable for long days in the hills, mixed terrain, or extended trail sessions.
Cube have only ever used Bosch drive systems on their Stereo models, and that hasnt changed with this latest model update. Always getting the very best Bosch motor of the year, for the last several years this has been the latest version of the Bosch Performance CX motor. With 85Nm and upto 340% assistance, its one of the most powerful motors legally available to consumers in the UK and has an outstanding performance and reliability record among riders of all types and ages.
That depends on your use. If you just ride easy forest trails or smooth singletrack, a lighter, less aggressive e-MTB may be more practical. The ONE77 is built for more demanding terrain — so unless you plan to use its full potential, you might not need all that travel and power.
Compared with lighter trail-oriented e-MTBs, the ONE77 sacrifices a bit of nimbleness and maybe some climbing-specific agility — but gains far greater stability, suspension performance, and versatility on rough, technical or mixed terrain. It’s more of a “go anywhere, ride anything” bike than a “commute or casual trails” option.
It depends on the version: higher-spec variants use drivetrain and brake components from SRAM AXS or Shimano XT, often with 12-speed gearing and strong hydraulic disc brakes for reliability on steep climbs and descents.
