DirtySixer is a company that specializes in making bikes for very tall people, including pro basketball legends like Shaquille O’Neal, Bill Walton, and Lebron James.
Dirty Sixer was founded by David Folch, who is 6-foot-6. It had always bothered him that extremely tall guys like himself had a hard time finding bikes that fit them. After he broke some bones in a bike crash on a regular-sized bike in 2011, he decided to learn how to make bikes for taller riders like himself. He started making bikes almost 15 years ago, and a number of pro basketball players started buying his bikes and helped him get his business off the ground.
DirtySixer recently sent us a photo of the 32-inch-wheeled full-suspension bike that they’re planning to release in March. You can see that bike if you scroll farther down.
While checking out their website, we found a bunch of photos that show how their 32- and 36-inch bikes compare to each other and also to 29-inch bikes, which we’ll share below:
David Folch on the left, stands with one of his 36-inch bikes, while one of his friends stands with a 29er.
Here’s another comparison:

We’re pretty sure the rider on the left is a pro basketball player, who is close to 7-feet tall. Folch, on the right is 6-foot-6, and the 32er looks like it’s perfectly proportioned for his height.
Below you can see how David Folch looks riding one of his 32-inch bikes next to a more average-sized rider on a 29er.

Below, you can see DirtySixer’s Monster Enduro, the company’s soon-to-be-released, 32-inch-wheeled, full-suspension bike. DirtySixer will be taking preorders next week.

This new, DirtySizer Monster Enduro mountain bike with 32-inch wheels is expected to go into production in March.
By the way, if anybody wants to see a size guide for DirtySixer’s 32″ bikes, check out the sizing guide for their hardtail 32-inch mountain bike that DirtySixer shared on their website:
Their XL size is designed for riders from 5’9″ to 6’3″. The 2XL size is designed for riders from 6’3″ to 6’7″. Their 3XL size is designed for riders for 6’7″ to 6’11”.
Riders who are 7 feet tall or bigger should probably stick with the 36-inch-wheeled mountain bikes that DirtySixer offers.
