LOL: San Fran's Big Wheel race was a marathon of hilarious crashes

(CBS) - Sunday was the 11th annual Bring Your Own Big Wheel derby in San Francisco. Imagining a bunch of grown adults on tiny, plastic bikes racing down a hill? That's exactly what it is. Is it even necessary to mention that there were a ton of hilarious crashes? Hit play and see for yourself.

The event drew over 2,000 celebrants to Potrero Hill, one of the steepest streets in the city. "It's total chaos - everyone's screaming and laughing, people are spinning out, going down backward," one spectator told the San Francisco Chronicle. "It's great. The whole point is to crash." It's good to know the racers aren't afraid to FAIL.
