The new eMTB+ riding mode delivers dynamic support at the highest level, blending the smooth control of eMTB mode with the full power of Race mode - offering up to 600% maximum support. It's available as part of this new firmware update.
Extended boost remains easy to modulate like in eMTB mode, while unleashing the full force of Race mode when needed. Up to 750 watts of power is delivered naturally and responsively, based on your pedal input. eMTB+ gives you the best of both worlds - combining agility, performance, and control for a truly natural riding experience. It is also possible to maintain peak power for longer, depending on riding conditions.

Brakes & Gears
Stopping power is supplied by dependable Shimano BR-MT200 hydraulic disc brakes operating on 180mm rotors front and rear. This low-maintenance braking setup provides linear lever modulation, immediate bite, and predictable control on rain-slicked tarmac, loose gravel, and muddy forest descents alike.
Whether navigating steep off-road slopes or stopping smoothly in town traffic, riders of the 2027 Cube Reaction Hybrid ONE benefit from low-maintenance reliability, swift lever response, and absolute braking confidence on every ride.
Drivetrain duties on the 2027 Cube Reaction Hybrid ONE are handled by a robust 12-speed Shimano Deore system featuring a wide 10-51T cassette and heavy-duty KMC e12 chain. Controlled by a single-click Deore thumb shifter, the ShadowPlus rear derailleur executes crisp, surgical gear changes across every sprocket under motor torque.
This expansive gear spread ensures an ideal pedalling cadence whether grinding up steep mountain gradients or cruising along flat fire roads on extended weekend trail rides.
Shimano BR-MT200 hydraulic disc brakes with dual 180mm rotors provide predictable, controllable stopping power and consistent lever feel across wet tarmac, loose gravel, and muddy forest tracks.
The Shimano Deore 12-speed ShadowPlus rear derailleur executes fast, accurate gear changes, using an integrated chain clutch to eliminate chain slap across rough cobbles and unpaved off-road trails.
The Shimano Deore 12-speed single-click shifter provides crisp, ergonomic thumb actuation while preventing accidental multi-shifts under high motor torque, protecting the chain and cassette from premature wear.
Wheels & Tyres
The Cube Reaction Hybrid ONE 2027 uses an ACID SLX 30 wheelset which features a wide, tubeless-ready rim design built specifically to withstand aggressive off-road hardtail riding and heavy motor drive.
Constructed with Boost axle dimensions (15x110mm front, 12x148mm rear), these wheels offer excellent lateral stiffness and efficient power transfer. The wide 30mm rim profile cradles high-volume 2.6-inch tyres perfectly, enabling lower inflation pressures that improve ride comfort, cornering grip, and off-road traction.
Schwalbe Smart Sam 2.6-inch tyres feature a versatile off-road tread pattern, combining a fast-rolling central track with grippy outer shoulder knobs.
Their high-volume casing absorbs trail chatter and loose rocks, while the wide contact patch provides outstanding cornering stability and traction across mud, gravel, and wet roots, making every trail adventure fast, smooth, and worry-free.
