With a collapsed size of 3 feet by 3 feet by 1 foot and a weight of 27 pounds, the SwissBike XO ($2,439) puts a lot of bike in a little space. But this is no folding commuter—it’s a true mountain bike with 27 speeds, a Rock Shox Recon suspension fork, and hydraulic disc brakes to meet the demands of both trail and traffic. At the end of the ride, release the levers to collapse the bike to its folded state.
