We specialize in designing truly refined frames, and the Reaction Hybrid is no exception. With its carefully hidden PowerTube battery and the built-in Bosch CX drive, many clever features are concealed behind its sleek lines. 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 slim aesthetics, while a UDH derailleur hanger makes it as flexible as possible. There is also an integrated chain guide and it is also prepared to accommodate ACID fenders. Finally, with the SizeSplit system, it's easy to find the perfect model for every cyclist. We've thought of everything so you can focus on enjoying your ride.
