The DirtySixer® bikes brand started by accident. Literally. 

Being 6'6" (or 198cm) I’d never had a bicycle built for someone my size. I was riding a regular bicycle (with 700c or 29er wheels) that was made as an afterthought for tall riders. It was unstable and flimsy, and as a result I crashed going over a curb and broke several bones. 

So while I was healing in a cast, I learned how to design and later fabricate a better, bigger, safer bicycle that would have big proportionate 36-inch wheels and look amazing. The DirtySixer® was born, growing a community of tall riders on their unique, big-wheel DirtySixer® bikes. 

If you’re tall or really tall, there’s a good chance you’ve never had a bicycle your size; you’ve never experienced the joy of riding comfortably and safely—until now. 

Since 2013, DirtySixer® has been on a mission to provide the biggest, safest, most comfortable bicycle for every body. Many pro athletes have chosen the DirtySixer® bikes, including Shaquille O’Neal, Mark Eaton, and Rudy Gobert. My goal is to make this big wheel experience accessible now to more people, so they can, too, feel like a kid again.
