Filmed by Lucas Brunelle over the course of a decade, Line of Sight is a new documentary giving us a rare view into the world of underground bicycle messenger racing, something which has become a global phenomenon over the past few years.

With a camera strapped to his customised helmet, Brunelle has been capturing the fastest, most skilled urban cyclists everywhere from Mexico City to the Great Wall of China. The 60 minute film will also be accompanied by a 40-page art book featuring photography and spoke cards from the Alleycat races.

The film will be available to buy from Lucas Brunelle’s website from 1 July, 2012. For now you can just check out the trailer:
