OCC was in the business of building custom motorcycles for individuals before it gained fame building themed projects or was featured on television. OCC has returned to that business while incorporating some of the designs that made them famous. The Web production bike is inspired by the Black Widow theme bike and other bikes which have incorporated spider webs into the design. The Greeny is an old-school style chopper designed by Paul Senior. The OCC Original includes many of the design elements that have made OCC famous including the heavy frame, wide back tire and wide rake on the front forks. The splitback features a unique split gas tank originally conceived from theme bikes on the show. A T-Rex Softail and a T-Rex Rigit were also available in the production series in the past.

Paul Senior's love of the style led him to create a number of Old School style choppers including 10-Up old School, Greeny, Maroon and Gold, Orange Bobber, The Blue Bomber, Little Red, Old School Vette, Orange Knucklehead, Pitchfork, Triumph Flames and Sunshine. The Greeny model is available for purchase from the production series.

In recognition of the shows growing fanbase, a contest was held to select fans which would receive custom built bikes. Winners were visited by the designers and asked to describe their dream bike. Winners include Jeff Clegg's Corporal Punishment, Susan Morisset's Female Snake Bike, Joseph McClendon's Custom Hog, and Bryan King's Vertebrae Trike.

OCC also works on a number of theme projects which are not featured on the television show.
