We make the World's Best Trike Rear End Conversion Kits. Est. 2005 in Pleasanton, Kansas

Since 1995 Frankenstein Trikes co-owner Frank Pedersen has designed and produced award winning Choppers, Custom motorcycle frames and Trikes. In 2005 Frank Pedersen and long time friend Steinar Bergby decided the Trike industry needed the next generation of Trike rear ends. Frank and Stein adapted their experience in design, style and fabrication to create the revolutionary Frankenstein Trikes Hot

Rod Trike Rear end. The Frankenstein Trike rear end was originally conceived to provide a custom Trike rear end that was lighter, stronger, narrower, more reliable and better looking than what was available. We introduced the 30” Hot Rod Trike rear end and custom bike builders loved it. What we didn’t expect was the overwhelming interest from individuals who wanted to convert their stock bike into a Trike. As a result, we made wider rear ends that are better suited for stock bike conversions. Gradually, with each conversion we designed swing arms, fenders, fender brackets and sourced wheels and tires. Within the first two years we developed kits for most Harley Davidson models. Now we offer our customers complete, simple bolt-on Trike kits, that can be installed in one day. Quality and design set us apart from our competitors. We use only the best components and materials such as Dana differentials, 9” Ford street/strip axles, billet 4 piston calipers, stainless steel rotors, grade 8 or better hardware and 6061 T6 Billet aluminum. We are constantly adding new products, listening to user feedback and expanding the options available to our customers. Our Trike Kits are manufactured right here in Pleasanton, Kansas, USA. We want our customers to have a satisfying experience when purchasing, installing and owning a Frankenstein Trike kit. Our entire staff is dedicated to quality and continuous improvement. Choosing a Trike kit is an important decision, we expect you to compare our Trike kits to those of other manufacturers. We believe, the more you compare, the better we look.

Craig's Custom 'Street Tractor' - Reverse Articulating Harley Sportster 1200 Trike, built by Frankenstein Trikes 😎

Craig came to Frankenstein Trikes with a very particular Trike vision. While this absolutely isn't a usual build for us, we couldn't help but make Craig's dream a reality!

This build started with a Sportster 1200, but with the engine hanging over our Frankenstein Trikes rear end! Craig was inspired by the articulating front end of earth-moving wheel tractor scrapers.

With the diehard dedication of master fabricator Mike Jensen and the help of the Frankenstein Trikes team, we were able to bring Craig's vision to life!

Since filming, Craig has updated the ‘Street Tractor’ with Center Line wheels and Front Runner tires.

Filmed at McCoy Park in historic Independence, Missouri.

"I built this this Trikester so I could still ride. I did everything by myself. I had a stroke in March a year ago so I lost a lot of strength on my left side. It was a little rough sometimes, but I loved every single minute of the build. Thank you for taking time to look at it." -Mike B, one of our wonderful customers.

The Trikester looks great, Mike! Ride safe! 😎
