we only built with the best Dr. Jekill & Mr. Hyde custom bikes

Motorcycles are remarkably personal and intimate items. Life is too short to ride a motorcycle that doesn’t make you smile every time you ride it. With so many options out there, there’s no reason to settle for something less than exactly what you want. 

We understand this need and are delighted to work with several custom builders around the world. Custom builders provide customers with bikes that aren't available through mainstream channels. Completely tailored to individual needs.

On this page you can find a selection of unique custom projects with several of our respected custom friends. Cause we only built with the best.

chopper kultureProject 21

When Dr. Jekill & Mr. Hyde started the project to develop a 2-in-1 clubstyle/performance exhaust, we knew we needed a special bike to showcase it. This should not just be a clubstyle bike... no this had to be next level; a bike that would stand out from te crowd and make heads turn when it would ride past you. Therefor it makes us proud that we can present Project 21 to you; a true california clubstyle Low Rider S, that combines the best features from design and looks on the one hand and performance and handling on the other.
