Probably best to watch this video first! It tracks a bunch of bikers racing through the crowded streets of our fair city-- weaving in and out of traffic. You've got to have balls of steel to be crazy enough to contemplate doing this for a living. Bonus: Lucas' other biking vidoes, and our favorite bike-blog. Also, Times-Up is having a memorial rally today at 2:45 at the Manhattan Side of the Williamsburg Bridge-- it's dedicated to the 21 bikers who were killed in traffic accidents this year.
