Size Guide

Choosing the right size dirt jumper isn't quite as straightforward as other bikes. The right size for you is based off a combination of height and riding style. If you are looking for quick handling in tight spaces like a skatepark you may prefer a smaller size. For those looking for stability in pump tracks, slalom and other scenarios, the long option may suit your needs better. A rough guide for sizing can be seen below:

Short: 5'1" - 5'9"
Long: 5'9" to 6'3"
