The Cube Stereo Hybrid ONE44 EX 800 in Blackline is the "Swiss Army Knife" of Cube’s 2025/2026 trail lineup. While its siblings like the Action Team or TM are purebred mountain chargers, the EX (Executive/Expert) trim is designed for the rider who wants a high-performance trail bike that can also handle "all-road" duties.
Unlike the more expensive HPC models, the ONE44 EX utilizes the HPA (High Performance Aluminium) frame. This makes it slightly heavier but significantly more versatile; it features integrated mounting points for a kickstand, full-size mudguards, and even a rear luggage rack—features usually omitted from pure carbon enduro bikes. It’s the ultimate "do-it-all" machine for someone who commutes during the week and hits the technical Alps or local trails on the weekend.

Key Highlights
The "Stealth" Commuter: Because it has mounts for a rack and fenders, this is one of the few 140mm full-suspension bikes you can legally and easily turn into a high-speed touring or trekking bike.
RockShox Psylo Fork: The Psylo is a revived nameplate for 2025, offering a much stiffer chassis than the old Recon or 35 Gold forks, giving you more precision in the corners.
4-Piston Shimano Brakes: Even though this is a more "accessible" model, Cube didn't skimp on stopping power. The MT520 brakes provide the same heavy-duty performance found on downhill bikes.
800Wh Endurance: With the massive 800Wh battery and the efficient 12-speed Shimano drivetrain, this bike is capable of 100km+ adventures on a single charge if managed correctly.
