Cody Connelly was born to Sean Connelly & Darci Dembeck. He has a younger sister named Tylar Connelly. At the age of five he received his first bike, an XR-50. Connelly learned how to maintain bikes from his father by working on their bikes together.
Connelly's first job was at Orange County Choppers (2001–2007), during which he attended Valley Central High School (Graduated 2005),BOCES and AMI (American Motorcycle Institute). The tuition fee for AMI was paid by Orange County Choppers as part of his training; therefore after attending AMI, Connelly returned to work at OCC.
In October 2007 Connelly left to team up with Vincent DiMartino at V-Force Customs.
Subsequently, Connelly sued Orange County Choppers and Paul Teutul, Sr., seeking damages for misappropriation of likeness, breach of contract and fraud. He claimed the show used his likeness in posters, coloring books and other merchandise after he left it in October 2007. Connelly also claimed that he never received "an old school chopper" that he helped design, though the shop's owner, defendant Paul Teutul, Sr., gave it to him in one episode of the show.
In November 2010, it appeared that John Marcus Odendahl (Odie) was fired from Paul Jr. Designs. Connelly appeared to fill his shoes and has appeared in several other episodes working with PJD. After several builds together, Paul Jr. offered Connelly a full-time job with PJD, which he accepted.
