For 2026, Cube’s renowned Stereo Hybrid electric mountain bike range builds on the success of the previous EMTB lineup, introducing the latest trail-ready Stereo Hybrid ONE44 and the enduro-focused Stereo Hybrid ONE77. Both models are powered by the latest Bosch Performance Line CX Gen 5 motor, (now tunable up to 100 Nm of torque) whilst the SLT gets the latest CX-Drive Unit and paired with a massive 800Wh Bosch PowerTube battery for unmatched range. The 2026 line is more advanced than ever, featuring innovative upgrades like the Bosch ABS e-bike technology (on AT & ONE44 SLX EVO models) and integrated Kiox 400C displays on select specs.
While both models share the same powerful Bosch CX gen 5 motor.. now tunable to 100Nm of torque and huge 800Wh battery capacity for all-day adventures, their designs diverge sharply to suit different riding styles:
- The ONE44 is the ultimate trail specialist, built for agility and all-day pedalling efficiency. It runs a traditional full 29-inch wheelset and features 150mm/140mm of balanced suspension travel, making it perfect for long mountain trails and varied terrain.
- The ONE77 is the gravity-focused full suspension enduro powerhouse. It’s built for "big lines and rowdy trails," featuring 170mm of travel front and rear and a stability-enhancing mullet setup (29-inch front wheel, 27.5-inch rear wheel) to inspire serious confidence on the steepest descents and gnarliest terrain.
