Introducing...

Old Skool Cycle Werks (OSCW) designs functional and versatile aftermarket motorcycle accessories. OSCW takes great pride in designing and developing the most innovative and aesthetically-pleasing aftermarket accessories on the market. Timeless design, quality craftsmanship, and innovative function.

OSCW’s do-it-yourself concept, allows you to easily transform your stock bike into three distinctive custom styles: Street Cruiser, Bagger or a Full Dresser. All with one bike and no frame modification. An affordable option to customize your bike without paying a custom builder.

The PhatBack™ and other OSCW aftermarket motorcycle accessories were originally designed for the Harley-Davidson Touring models by Henry T. Chriss, owner of Henry Thomas Designs, LLC.

OSCW’s flagship product is the PhatBack™ – A one-piece, hand-laid fiberglass conversion kit. A Street Cruiser designed to resemble the classic American cars from the 1940s and 1950s. Cars that had a streamlined, smooth and fluid look with fender skirts and integrated running boards.

The PhatBack RT™ is the same kit with a rumble trunk. Street Cruiser look with an integrated storage compartment that opens like a rumble seat in the classic American cars.

The PhatBags™ (hard bags), SlingBlade™ (front fender) and SlipStreme™ (café style fairing) are OSCW’s recent designs for the Harley-Davidson Touring models. Designed to transform your bike to Bagger and Full Dresser. Affordable, functional, easy-to-install customization.

Future designs underway for the Harley-Davidson Touring models are the PhatBox™ (touring box) and TailGator™ (pull-behind trailer). Accessories for the Harley-Davidson Softail models and various metric bikes (Honda, Kawasaki, Suzuki and Yamaha) are also underway.
