Inside the dangerous world of a New York bike messenger
9 April 2012 Last updated at 15:36 BST
Zo has been a bike messenger in New York for a decade. His name is short for "Schizo" - a nickname he gained in school because he always seemed to be in many different places at the same time.
Born and raised in Brooklyn, Zo started working at AtoZ Courier in Manhattan at the age of 21 when the messenger market was still booming.
Today, half the clients have gone and Zo is left delivering items that can not be sent over the internet - but he says he loves the job.
The BBC caught up with Zo in Manhattan's Lower East Side where he explained how he navigated the city's busy streets and how riders feared pedestrians who started "the dance" when half way across.
