What do you do after you set the record for human-powered flight and bag the Sikorsky Prize by floating around in a pedal-driven helicopter? You break the human-powered speed record, of course -- at least that's what's AeroVelo has planned. The team has made a habit of engineering machines that make the most of the human engine, and their latest project hopes to give mankind the ability to ride bicycles at 87 mph.

The team's 140 km/h target speed sounds ambitious on its own, but the goal seems even more daunting when pitted against the current record: 133.78 km/h (83mph). That record was set by adding a measly 0.6 km/h to the previous top speed; besting it by a solid four miles per hour is definitely a bold ambition. That said, breaking records isn't easy -- or cheap -- and the team has launched a Kickstarter campaign to help it fund development of its ETA Speedbike Project. Funds will be used to help them complete the project in time to compete in the World Human-Powered Speed Challenge in Battle Mountain, Nevada this September. Want to help make history?
