For 2027, CUBE’s Stereo Hybrid electric mountain bike range expands with updated ONE44 and ONE77 models, covering everything from versatile trail riding to more demanding enduro terrain. The range also introduces a major choice of drive systems, with selected ONE44 models powered by the Avinox M2S, while the wider ONE44 and ONE77 ranges continue with Bosch Performance Line CX and CX-R power.
The Bosch-equipped models combine up to 120Nm of torque with an 800Wh PowerTube battery, while the Avinox-powered ONE44 EXC and Super TM deliver up to 150Nm of torque (comparison pending), and a removable 800Wh battery. Selected models also feature electronic shifting, integrated displays and Bosch ABS Pro braking technology.
Although the ONE44 and ONE77 share CUBE’s trail-focused design and adjustable geometry, they are built for different styles of riding:
- The ONE44 is the versatile trail all-rounder, combining up to 150mm of front suspension with 140mm of rear-wheel travel. Medium to extra-large models use 29in wheels, while size small uses 27.5in wheels. Its balanced handling makes it well suited to technical trails, long mountain rides and varied terrain.
- The ONE77 is the more gravity-focused e-enduro bike. It features 170mm of suspension travel front and rear, together with a mullet wheel setup consisting of a 29in front wheel and 27.5in rear. This gives it greater stability and control across steep descents, rough enduro trails and bike park terrain.
This buyer’s guide compares the 2027 CUBE Stereo Hybrid ONE44 and ONE77 ranges, examining the suspension, drivetrains, brakes, displays, motor systems and prices across the carbon models to help you choose the right electric mountain bike for your riding.
