Be The Bike

This Bike patent (I believe it is still just a patent) is powered by gravity which means you need a good sized hill to use it. Your legs are strapped to the back wheel and you brake by squeezing your legs together like a ThighMaster. Quite crazy it seems! Body armor is recommended as you are strapped to the wheel and if you catch the floor on a tight turn then its going to hurt. From the picture above you can see why it is named, be the bike.
