We specialize in designing truly refined frames, and the Reaction Hybrid is no exception. With its carefully hidden PowerTube battery and the integrated Bosch CX drive, the sleek lines conceal many intelligent features. It is PowerMore compatible, allowing you to easily add up to 250 Wh of additional battery capacity. The saddle clamp and integrated cable routing complete the clean aesthetic, while a UDH derailleur hanger makes it as adaptable as possible. There is also an integrated chain guide and it is ready to accommodate ACID mudguards. Lastly, the SizeSplit system makes it easy to find the perfect model for any rider. We've thought of everything so you can focus on enjoying your ride.
