2025 Cube Reaction Hybrid Race 800 Electric Mountain Bike in Blue
With its rugged go-anywhere capability and a high-capacity battery, there's not much that can hold the Reaction Hybrid Race back. It's even PowerMore-ready, so you can add an optional extra 250 Wh battery for even more range. The smart system-equipped Bosch CX drive has the power to make any route easier, and Shimano XT 12-speed gears put the right ratio literally at your fingertips. We chose wide, grippy Schwalbe 2.6in tyres and paired them with an air-sprung RockShox Recon Silver fork for the best blend of comfort and control. With strong 4-piston hydraulic disc brakes, you're assured of safe and predictable stopping in any conditions. And there's a dropper post too, so you can take the path less travelled, and see where it leads.
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.
