A Set of Wheels That Go Zoom

Getting around the city is much easier with a set of wheels. The Skatecycle, invented by New York City's own Brooklyn Workshop, is the ultimate way to traverse the city without expending excessive amounts of energy. While skateboarding and rollerblading require energy and force to go, the Skatecycle is the world's first self-propelled hubless skate. There are no batteries; you slide your feet onto the two slip-resistant plates, and you simply weave along flats or carve down hills like a snowboarder. The Skatecycle also folds up, making for easy storage or transport.
Cost: $149.95 on BrooklynWorkshop.com.
