New Cube Reaction Hybrid Pro FE 800 2026
Reaction - Urban and off road capable
The Cube Reaction Hybrid 2026 combines the efficiency of a hardtail with the seamless support of Bosch’s Performance CX drive unit, making it a highly capable electric mountain bike for trail riding, commuting, or weekend adventures. The 800Wh PowerTube battery is neatly integrated into the frame, giving the bike clean lines and long-range performance.
Attention to detail is everywhere: an integrated seat clamp and internal cable routing enhance the sleek design, while a pre-installed chain guide adds reliability on rougher terrain. The frame is ready to accept ACID mudguards and a luggage carrier, and with X-Connect, adding a compatible ACID front light is as simple as plugging it into the headset.
For riders who want to go even further, the Reaction Hybrid is PowerMore-ready, allowing the addition of an optional 250Wh range extender. And thanks to Cube’s Size Split system, there’s a perfectly proportioned frame for almost every rider.
Bosch Purion 200 display
Control unit with compact colour display and fully networked in the smart system: that's the Purion 200. The all-in-one solution ensures an uncluttered handlebar, is in close proximity to the thumb and offers a razor-sharp display of ride data as well as simple, ergonomic control of all eBike functions. Combine the Purion 200 with an additional display – for even greater convenience.
Big travel. Bosch power. Trail ready.

Reaction Hybrid Pro FE 800 - in depth
Best of all worlds: the Reaction Hybrid Pro FE combines the versatility of a fully equipped tourer and the ruggedness of a mountain bike, with added Bosch power. The mudguards, luggage carrier, kickstand and lights are just the start. You can also tackle any route, off-road or on, with ease thanks to an 800Wh battery and 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 strong 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.
