People do a lot of strange and dangerous things for fun and thrills, but biking downhill at 60+ miles per hour takes some serious guts. This gravity bike designed and built by Jeff Tiedeken was designed to handle crazy speeds and make you feel like you’re flying down hills.

The bike is noticeably missing some typical elements: pedals and a chain. That’s because it is meant strictly for downhill racing. You start at the top of a hill, hunker down and let gravity take you all the way to the bottom.

To the bike creator’s credit, he did put brakes on it so riders don’t have to drag their feet to stop. It would take a whole lot of guts – and ideally a whole lot of protective gear – to hop onto this sleek lightweight bike and hurl yourself down a hill at breakneck speed.
