The Reaction Hybrid Pro combines mountain bike versatility with Bosch-powered ease of use and clever CUBE design. Tackle any route, off-road or on, thanks to an 800Wh battery and smooth, powerful Bosch CX drive. Combined with Shimano's easy-to-use XT 12-speed gears, it's all you need to comfortably ride any hill. For coming back down the other side, we fitted powerful Shimano 4-piston hydraulic disc brakes and grippy Schwalbe 2.6in tyres. There's also an air-sprung fork with 120mm of travel (100mm for small frame sizes and for all Easy Entry models), and a remote dropper seatpost for extra comfort and control on rougher trails. It's got it all – the rest is up to you.

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.
