Eclipse S18

The Road Warrior

This ain’t your mama’s folding bike. With integrated lighting powered by a super-efficient dynamo hub, front and rear racks, a floor pump in the seatpost, and big beefy 507 mm tires that munch potholes for lunch, the Eclipse S18 is the ultimate hard-core commuter that will get you through the Zombie Apocalypse. Great for traversing the urban jungle or trekking it alone in the wild countryside.
