Watch a horde of mopeds ride the Alps

Red Bull, patron of all things slightly mental, has organized a gathering of moped enthusiasts in Switzerland for the past three years. The attendees don't just sit around and gawk at each other's machines, though. The Red Bull Alpenbrevet is an 82-mile rally, and the course forces participants to use their mix of human and internal combustion power to tackle a total of three 7,000-foot passes. This year, 770 riders came out to compete for the gold. There was more than one way to go home a winner, however. The Alpenbrevet also features a "style" competition, and many riders gussy up both their classic mopeds and themselves for the day.
