Welcome to BrassBallsCycles.com!

At Darwin Motorcycles we meticulously hand craft Uncompromising American Motorcycles, bespoke for discerning customers. We are a federally licensed manufacturer with NHTSA assigned VIN numbers, allowing our bikes to be financed & insured. We've won numerous awards and are the only company to win AMD World Championships of Custom/Production Bike Building 2 years in a row.

Brass Balls Cycles Bike Kits are the only bike kits designed with the customer/builder in mind. We offer them in 5 separate & customizable phases so you can build as your time and budget allows. Our kits have been thoughtfully designed, derived from years of experience building our award winning custom/production bikes. We are here for you every step of the way and can't wait to see your completed bike.

Over the years we have built & customized several bikes to support our troops. Our charity of choice is Pros4vets.org. We are currently seeking sponsors to help us provide bike kits for soldiers with PTSD.

We appreciate your patronage.
