Cube Stereo Hybrid One44 HPC SLT 800 2027
The Perfect All-rounder. Powerful & Precise.
The Cube Stereo Hybrid ONE44 HPC SLT 800 is the flagship model in Cube’s full-power electric trail bike range. Its lightweight High Performance Composite frame combines 150mm of front suspension with 140mm of rear travel, creating a fast and controlled platform for technical climbs, rough descents and demanding all-day rides.
A Bosch Performance Line CX-R motor and integrated 800Wh PowerTube battery provide substantial power and range. Fox Factory suspension, SRAM XX Eagle AXS Transmission, Magura Race Pro brakes and a premium Newmen Phase wheelset complete a specification designed for riders seeking top-level electric mountain bike performance.
Bosch Performance Line CX-R Motor
The Bosch Performance Line CX-R is the race-focused version of Bosch’s full-power electric mountain bike motor. Delivering up to 120Nm of torque, 750 watts of peak power and support of up to 600%, it provides rapid acceleration and the assistance required for steep, technical climbs.
Its exclusive Race mode delivers support more quickly and extends assistance after the rider stops pedalling, helping maintain momentum over rocks, roots and stepped trail features. The motor’s sensitive response also allows power to be controlled when traction is limited, giving the rider strong support without making the bike difficult to manage.
The Bosch eBike Flow app can be used to personalise compatible assistance modes and adjust the motor’s performance. Higher settings prioritise maximum climbing assistance, while reduced outputs can help conserve battery capacity and deliver a more natural ride feel.
An integrated Bosch PowerTube 800Wh battery provides the capacity required for longer trail rides and bigger days in the hills. Its positioning inside the down tube maintains the frame’s clean profile while keeping 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. Its clear interface 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 display screens without taking a hand away from the handlebar. As part of the Bosch Smart System, the Kiox 400C also connects with the eBike Flow app for ride recording, system updates and personalisation of compatible settings.

Fox Factory Suspension
A 150mm Fox 36 Float Factory fork uses the GRIP X2 damper to provide extensive high-speed and low-speed compression and rebound adjustment. This allows the fork to be precisely tuned for the rider, terrain and preferred handling characteristics.
The stiff 36mm chassis maintains steering accuracy through rough trail sections, while Kashima-coated upper tubes help reduce friction for smooth and responsive suspension movement. The fork is paired with a Fox Float X Factory rear shock, creating a balanced 150mm front and 140mm rear suspension platform.
Together, the two suspension units provide sensitivity over smaller trail chatter, support through corners and compressions, and controlled movement across larger impacts. This gives the Stereo Hybrid ONE44 HPC SLT 800 the versatility required for technical climbing and aggressive descending.
SRAM XX Eagle AXS Transmission
SRAM XX Eagle AXS Transmission provides fast and precise electronic 12-speed shifting without a conventional mechanical gear cable. Its robust full-mount construction is designed to handle demanding riding and the increased drivetrain loads produced by a full-power electric mountain bike.
A wide-range 10-52T cassette provides an extremely low climbing gear for steep gradients while retaining efficient ratios for faster trail sections. Electronic controls create a clean cockpit and deliver consistent gear changes throughout the ride.
The drivetrain is paired with a Race Face ERA E-MTB crankset and 34-tooth chainring. Its premium construction helps reduce weight while providing the strength required for technical trail riding and high-torque motor assistance.
