Now available with the latest Bosch 2.0 update - delivering up to 120 Nm of torque
Cube Stereo Hybrid One77 HPC TM 800 2027
Full Power. Total Control.
The Cube Stereo Hybrid ONE44 HPC TM 800 is a hard-hitting full-power electric mountain bike designed for technical trails, steep descents and demanding all-day rides. Its lightweight High Performance Composite frame combines 150mm of front suspension with 140mm of rear travel, delivering the stability required for rough terrain without sacrificing responsive trail handling.
Power comes from the latest Bosch Performance Line CX motor and an integrated 800Wh PowerTube battery. RockShox suspension, SRAM GX Eagle AXS Transmission, powerful Maven brakes and a reinforced Newmen wheelset give the TM model a specification intended for riders who want to push harder on challenging trails.
Bosch Performance Line CX Gen 5
The Bosch Performance Line CX motor delivers up to 120Nm of torque, 750 watts of peak power and support of up to 600%. Its substantial output provides the assistance required for steep and technical climbs, while its responsive delivery helps the rider manage traction across loose, rocky and root-covered surfaces.
Eco mode prioritises battery efficiency, Tour+ automatically adjusts support as conditions change, and eMTB mode delivers progressive assistance for technical off-road riding. Turbo provides maximum support for demanding gradients and faster acceleration. Compatible motor characteristics can also be personalised through the Bosch eBike Flow app.
The motor is paired with a high-capacity Bosch PowerTube 800Wh battery, providing the capacity required for longer trail rides and bigger days in the hills. Integrating the battery within the down tube maintains a clean frame profile while helping to position its weight centrally and low within the bike.

Removable 800Wh Battery
An integrated Bosch PowerTube 800Wh battery provides the capacity needed for longer rides, sustained climbing and repeated enduro laps. Its position within the down tube maintains the bike’s clean appearance while helping to keep weight central within the frame.
Actual range will depend on assistance mode, elevation, terrain, rider weight and riding conditions. The large 800Wh capacity allows the rider to use the motor’s stronger assistance modes more frequently without needing to conserve power throughout the entire ride.

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 information including speed, 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.

Cube Stereo Hybrid One77 HPC TM 800 2027 - IN DEPTH
A 150mm RockShox Lyrik Select+ air fork provides the stiffness, support and controlled damping needed for aggressive trail riding. It is paired with a RockShox Super Deluxe Select rear shock, creating a balanced 150mm front and 140mm rear suspension platform designed to maintain grip and composure across roots, rocks and larger trail impacts.
SRAM GX Eagle AXS Transmission provides precise electronic 12-speed shifting, with a wide-range 10-52T cassette supplying the low gearing required for steep climbs. Its robust construction is designed to handle demanding trail use and the increased drivetrain loads generated by a full-power electric mountain bike.
SRAM Maven Bronze four-piston hydraulic disc brakes provide powerful and controlled braking across steep descents and technical terrain. Finished with a Newmen Beskar 30 Base/Strong wheelset, size-specific 27.5-inch or 29-inch wheels, a dropper seatpost and Cube X-Connect light compatibility, the Stereo Hybrid ONE44 HPC TM 800 delivers a capable specification in its Reedgreen ’n’ Gills finish.
