Cube Reaction Hybrid SLX 800 2026 Electric Mountain Bike

When you`re exploring new places, the last thing you want is to be worrying about your bike. That`s why the Reaction Hybrid SLX is equipped with Shimano`s XT 12-speed gears and matching XT 4-piston hydraulic disc brakes. Together, they offer easy use and exceptional reliability, so you can just concentrate on the ride. It`s the same story with the Fox 34 Float AWL suspension fork, which combines smooth bump-swallowing comfort with excellent steering precision. The Bosch CX drive and 800Wh PowerTube battery speak for themselves, offering quiet and unobtrusive pedal assistance for miles of smiles. The Newmen Performance 30 wheelset is shod with 2.6in Schwalbe Smart Sam tyres for excellent grip and ride comfort. And we even fitted a remote dropper post, for increased confidence on tricky trails. Where`s your next adventure?

Frame description
The Reaction Hybrid`s neat and tidy design is no accident. With the 800Wh PowerTube battery neatly concealed and the Bosch CX drive housed securely, its svelte lines disguise lots of clever features. It`s PowerMore-ready, making it easy to add up to 250Wh of extra battery capacity. The integrated seat clamp and cable routing complement the clean aesthetic. There`s a pre-installed chain guide, and it`s ready to accept ACID mudguards and a luggage carrier... plus, with X-Connect, adding a compatible ACID front light is as simple as plugging it into the headset. And, with Size Split, it`s easy to find the perfect fit for every rider. We`ve thought of everything, so you can just ride.

Previous model reviewed. Absolutely love the One77. Stable, aggressive, and insanely confidence-inspiring on descents, yet climbs better than expected. Powerful motor, great range, and bombproof components. A true no-compromise e-enduro beast.
