The DirtySixer® bikes brand started by accident. Literally. Being 6'6" (or 198cm) 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. I crashed 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 would be good looking. The DirtySixer® was born, growing a community of tall brothers riding 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 and ever experienced the joy of riding in comfortably and safely. Until now. Many pro athletes have chosen the DirtySixer® bikes to ride, among Shaquille O’Neal, Mark Eaton, Rudy Gobert etc. My goal is to make this big wheel experience accessible now to more people, so they can, too, feel like a kid again.
