No, those aren’t handcuffs. Your feet go into them, and no, they’re not foot-cuffs either. This may be the next big thing in skateboarding: the Skatecycle by Brooklyn Workshop. The Skatecycle is the world’s first self-propelled hubless skate. Just slot your feet into the space where the hubs should be and carve down a hill like a snowboarder. The design lets you propel yourself along indefinitely without ever taking your feet off the plates. Very cool. Remember, you saw it here on TrailblazerGirl.com first.
