EXC 625 29


Color variants
Frame variants

Our smallest Reaction Hybrid frame is built around the powerful, versatile 625Wh battery. More compact and lighter than the battery featured in the larger frame sizes, it allows us to create the perfect Agile Ride Geometry for shorter riders without compromising performance or comfort. The result is a bike that's a perfect match to your body size. It's also lighter, easier to handle and huge fun, with the motive force of Bosch's proven fourth-generation drive unit giving your legs and lungs a boost. And it still has all the features you'd expect, like internal cable routing - with provision for a dropper post - and a 1.5in head tube for precise, confidence-inspiring steering.
