Form follows function. The Reaction Hybrid Performance's elegant PowerTube frame conceals a large-capacity Bosch battery inside the down tube for sleek looks and better protection from the elements. Internally routed cables match the clean design aesthetic, offering long-lasting, low-maintenance gear-shifting accuracy. A Trapeze frame option gives riders who are more comfortable with a lower top tube an easy access option, without compromising performance. And, with Size Split, you can be assured of finding the perfect fit.
