We specialize in the design of truly well-crafted frames, and the Reaction Hybrid is no exception. With its carefully concealed PowerTube battery and firmly housed Bosch CX motor unit, its sleek lines hide many smart features. It is PowerMore compatible, allowing you to easily add up to 250 Wh of additional battery capacity. The integrated seat clamp and internal cable routing complete the clean aesthetic, while a UDH derailleur hanger makes it as upgradable as possible. There is also an integrated chain guide mount and it is also ready to accommodate ACID mudguards. Finally, with the SizeSplit system, it is easy to find a perfectly fitting model for any rider. We've thought of everything so you can focus on enjoying your ride.
