Stereo Hybrid ONE44 HPC PRO 800 / oldgrey'n'black

The Cube Stereo Hybrid ONE44 HPC Pro 800 in Oldgrey ’n’ Black is an all-mountain full-suspension e-MTB designed for technical trail centers, alpine loops, and multi-peak off-road adventures. Constructed with a C:62 carbon monocoque front triangle paired with a 6061-T6 aluminium rear end, it features 140mm of rear wheel travel balanced by a 150mm RockShox Psylo air fork. Tipping the scales at 24.6 kg (54.2 lbs), the chassis integrates Cube's angle-adjustable headset system to tweak the head angle for high-speed stability or tight singletrack agility.

Power is supplied by the Bosch Performance Line CX motor paired with a high-capacity 800Wh Bosch PowerTube battery integrated cleanly into the downtube. Cockpit telemetry is managed via a top-tube-integrated Bosch Kiox 400C display combined with a handlebar Bosch Mini Remote. Driven by a 12-speed Shimano XT rear derailleur across a 10-51T cassette, it stops with 4-piston Magura Louise hydraulic disc brakes clamped onto dual 203mm rotors.
