2025 Cube Reaction Hybrid Slt 800 Electric Mountain Bike in Red
There's never been such a capable Bosch-powered hardtail. The Reaction Hybrid SLT 's smooth, quiet Bosch CX drive, Kiox 500 display and PowerTube battery are just the start. We fitted Sram's XO Eagle Transmission 12-speed gears for their huge range and flawless electronic shifting precision. Then we added a pair of Magura's hard-wearing, heat-resistant Gustav Pro hydraulic disc brakes – which, combined with the grip from 2.6in Schwalbe tyres, ensure you're always in full control. Newmen Performance 30 wheels are both light and tough, and a remote dropper seatpost gives you the confidence to push your trail riding skills. And, last but by no means least, the Fox 34 AWL Float fork serves up all the trail-smoothing, rock-swallowing travel you need for better comfort and control. Ready? Let's go!
We specialise in really neat frame design, and the Reaction Hybrid is no exception. With the 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 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 it's also ready to accept ACID mudguards. 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.
