Bike Messengers With Mad Skills: A new documentary film called Line of Sight gives a helmet-mounted-camera view of bike messenger races known as alleycats. It was filmed by Lucas Brunelle, who spent 10 years gathering footage from all over the world, from the urban jungles of New York City to the real jungles of Central America, from the narrow maze of London streets to the Great Wall of China.

It's a rare view into messenger riding that few people see. In the trailer, which you can watch below, you'll see the kind of crazy skills these urban athletes have. The movie premiered in New York earlier this month and is available in DVD beginning July 1. via
