The OCC fabricators and mechanics such as Paul Teutul, Jr., "Slick" Rick Petko, Nick Hansford, Christian Welter, and former employees Vincent DiMartino (who left OCC to start V-Force Customs in 2007), and Cody Connelly (a BOCES student intern who has since joined DiMartino's business), create dozens of custom motorbikes. Michael Teutul, usually referred to as "Mikey", serves as the shop's custodian and webmaster, and provides comic relief to the show. He has been seen doing metal work occasionally, as one of his early jobs was working at Orange County Ironworks. Also featured occasionally is Danny Teutul, the second oldest child, who succeeded Paul Sr. as the owner of Orange County Ironworks. Danny visits to do contracted work for the OCC facilities. The show also documents their personal and promotional activities ranging from magazine photo shoots to family holidays and custom bike shows.
