64	9	"A New Company"	October 29, 2012
Senior and Junior begin brainstorming on their production bike company but, when they don't see eye-to-eye, the road is rocky from the get-go, leading Senior to jump the gun on the bike's design. PJD starts an unusual build for Cre8Play, a company based out of Minneapolis that designs and builds custom themed playgrounds. They agree to collaborate on an interactive PJD-themed playground that's based on their three most popular bikes (Anti-Venom, Black Widow and the Build-off P-51 Mustang bike). Meanwhile, OCC struggles to complete the Super Bike leading to more days of fabrication.
65	10	"Junior Frustration"	November 5, 2012
Senior makes business decisions without his son's approval. Junior then gets frustrated when he receives a call from Jason to discuss design aspects for the production bike when it was agreed that PJD would handle the fabrication. Meanwhile, OCC unveils the Super Bike to their client and restaurant partner at the OCC Cafe and later starts an old school bike for Big Ass Fans. PJD and Cre8Play complete the Black Widow, Anti-Vrenon and build-off bike-inspired playground and unveils it at the Anaheim Convention Center in Anaheim, California
66	11	"Old Wounds"	November 12, 2012
Senior throws down the gaunlet for a biker build-off rematch when he calls the show's producer Craig Pilgrim who adds a new player (the Fast N' Loud guys) to the competition. PJD collaborates with bicycle company Dynacraft to design bicycle versions of the "Black Widow", "Anti-Venom" and P-51 Mustang bikes. OCC runs into a problem with the Big Ass Fans bike before the unveiling in Kentucky. Meanwhile, tensions rise at OCC when Junior and Senior disagree on the production bike's design process when they're not on the same page choosing a frame.
67	12	"Troubled Waters"	November 19, 2012
The production bike's progress grinds to a halt when Senior and Junior disagree on a plan of action. PJD gets a call that their 911/Memorial bike is under 4-feet of water from Hurricane Sandy and they try to salvage what they can to rebuild it. Senior confronts Vinnie about their past differences. OCC unveils the Big Ass Fans bike at their R&D test facility in Lexington, Kentucky and then starts a three-bike build for The Venetian in Las Vegas. Meanwhile, PJD partners with Bioworld to design t-shirts of their most popular bikes to sell in retail stores.
68	13	"Impasse"	November 26, 2012
Senior pulls a prank for the biker build-off by creating a riveted used car for Junior and having the OCC crew deliver it to his shop. PJD works even harder to restore the 9/11 Memorial Bike. OCC finishes the first Venetian bike and starts fabrication on the second and third bikes. Then they start a new build for GAF Roofing after the guys "test" their Timberline shingles product. Meanwhile, the production bike discussions open old wounds when Pauly meets with his father in Jason's office causing things to get heated between Junior and Jason over their individual design processes.
69	14	"The Last Build"	December 3, 2012
OCC completes the GAF Roofing Bike and delivers one of the three Venetian bikes to the hotel in Las Vegas. PJD finishes the 9/11 Memorial Bike restoration. They also visit Staten Island, which was hit by Hurricane Sandy, to distribute food and supplies with Governor Cuomo. Vinnie and Cody come up with a new prank that uses the car OCC previously sent to them. Senior and Junior meet for lunch and find common ground when they reminisce about their lives at the time when the show first started. Both come to a realization that rebuilding their personal relationship is more important than being in business together, leading to a mutual decision to end work on the production bike.
70	15	"The End"	December 17, 2012
In this final episode of the series, Mikey reunites with his father and sits down with his brother as the three look back on a decade of memories. Meanwhile, both OCC and PJD crews reminisce about their time on the show. Also, Senior and Junior donate their father-son build "Teutul" bike to Motorcyclepedia, a motorcycle museum in Newburgh, New York.
