Now available with the latest Bosch 2.0 update - delivering up to 120 Nm of torque
Cube Stereo Hybrid One44 HPC AT 800 2027
The Perfect All-rounder. Powerful & Precise.
The Cube Stereo Hybrid ONE44 HPC AT 800 is a premium full-power electric mountain bike built for demanding trail riding, technical climbs and fast, challenging descents. Its High Performance Composite frame combines 150mm of front suspension with 140mm of rear travel, creating a responsive and controlled platform for riders who want high-end performance across varied terrain.
The latest Bosch Performance Line CX motor and integrated 800Wh PowerTube battery provide substantial power and range, while Fox Factory suspension, Shimano XTR Di2 electronic gearing and Bosch ABS Pro-assisted XTR brakes place the AT model at the top of the Stereo Hybrid ONE44 range.
Bosch Performance Line CX Gen 5
The latest Bosch Performance Line CX motor delivers up to 120Nm of torque, 750 watts of peak power and support of up to 600%. This gives the Stereo Hybrid ONE44 HPC AT 800 the assistance required for steep gradients and technical climbs, with responsive power delivery that helps the rider maintain grip across loose, rocky or root-covered terrain.
Eco mode prioritises efficiency, Tour+ automatically adapts support as conditions change, and eMTB mode provides progressive power for technical off-road riding. Turbo delivers maximum assistance for the steepest gradients and fastest acceleration. Compatible motor characteristics can also be personalised through the Bosch eBike Flow app.
An integrated Bosch PowerTube 800Wh battery provides the capacity needed for longer trail rides and bigger days in the hills. Positioning the battery within the down tube maintains the frame’s clean profile while helping to keep the additional weight central and low within the chassis.

Bosch Kiox 400C Display
The Bosch Kiox 400C colour display is integrated directly into the top tube, creating an uncluttered cockpit while protecting the screen from impacts. It clearly presents essential information including speed, remaining battery charge, assistance mode, estimated range and ride data.
A compact Bosch Mini Remote allows the rider to change assistance modes and navigate between data screens without taking a hand away from the handlebar. As part of the Bosch Smart System, the display also connects with the eBike Flow app for ride recording, system updates and personalisation of compatible settings.

Bosch power. Trail ready.

Cube Stereo Hybrid One44 HPC AT 800 2027 - IN DEPTH
Fox Factory Suspension
A 150mm Fox 36 Float Factory fork uses the GRIP X damper to deliver accurate control across technical climbs, rough descents and faster trail sections. Its stiff 36mm chassis provides precise steering, while the adjustable air spring and damping allow the fork to be tuned to suit the rider, terrain and preferred riding style.
The fork’s Kashima-coated upper tubes help reduce friction for a smooth and responsive suspension action. It is paired with a Fox Float X Factory rear shock, creating a balanced 150mm front and 140mm rear suspension platform that maintains grip over smaller trail chatter while providing support through corners, compressions and larger impacts.
Shimano XTR Di2 Drivetrain
Shimano XTR Di2 provides fast and precise electronic 12-speed shifting. The system delivers consistent gear changes without relying on a conventional mechanical cable, creating a clean cockpit and reducing the effect that cable contamination or stretching can have on shifting performance.
A wide-range 10-51T cassette supplies the low gearing required for steep technical climbs alongside efficient ratios for faster sections of trail. The drivetrain is paired with an ACID MTB Hybrid Pro crankset and 34-tooth chainring, creating a versatile gearing range for full-power electric mountain bike riding.
Shimano XTR Brakes and Bosch ABS Pro
Shimano XTR BR-M9220 four-piston hydraulic disc brakes provide the strong and controlled braking required for steep descents and technical trail riding. Their high braking force is balanced by usable modulation, allowing the rider to make controlled speed adjustments as grip and trail conditions change.
Bosch ABS Pro supports the front brake by monitoring wheel behaviour and regulating braking pressure during hard braking. The system helps reduce the risk of front-wheel lock-up and can improve control across loose, steep or unpredictable surfaces, while still allowing an experienced rider to brake assertively.
