2025 Cube Reaction Hybrid Slx 800 Electric Mountain Bike in Grey
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 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 AWL Float suspension fork, which combines smooth bump-swallowing comfort with excellent steering precision. The Bosch CX drive and 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?
You can't help noticing the Reaction Hybrid Allroad's neat and practical mudguards, lighting set, luggage carrier and kickstand, but there's far more to it than that. We call this frame Easy Entry because that's exactly what it does. With the PowerTube battery neatly concealed and the Bosch CX drive housed securely, it's also PowerMore-ready – making it easy to add up to 250 Wh of extra battery capacity. The integrated seat clamp and cable routing complement the clean aesthetic, whilst a UDH gear hanger makes it as future-proof as possible. There's a built-in chainguide mount too, and there are sizes to cater for most riders. We've thought of everything, so you can just ride.
