The Reaction Hybrid Pro 800 combines the versatility of a CUBE mountain bike with the powerful assistance of Bosch. Whether you’re heading off-road or sticking to the pavement, the 800 Wh battery and the smooth, quiet Bosch CX motor make cycling effortless. Need more range? The frame has space for a 250 Wh range extender. With the Shimano XT 12-speed transmission, you’ll always have the perfect gear, no matter the terrain. Heading downhill? Shimano hydraulic disc brakes and 2.6 inch Schwalbe tires ensure safe stopping power. An air-sprung suspension fork with 120 millimeters travel (100 millimeters for smaller frame sizes and Easy Entry models) and a hydraulic dropper seat post offer additional comfort and control on rough trails. This bike has it all – now it’s your turn to hit the road.
