CUBE Reaction Hybrid SLT 800

CUBE Reaction Hybrid SLT 800

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!

Bosch update July 2025: Are you ready for more power?

From July 2025, you can increase the torque of the Gen 5 Bosch motors (BDU38) to up to 100 Nm using the Flow app. Your advantage: noticeably more thrust and up to 400% motor support. You can use the eBike Flow app to customise the riding modes and adapt the performance precisely to your riding style.

Frame details

We specialise in really neat frame design, and the Reaction Hybrid is no exception. With the 800Wh PowerTube battery neatly concealed and the 85Nm 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.
