Step 3: Wheel Size

Dirt Jump / Slopestyle bikes use a standard wheel size of 26”. Specialized introduced a 27.5” wheel dirt jump bike, ideal for regular 29” mountain bike riders that feel 26” is a bit too small compared to what they’re used to.

Smaller wheel sizes, such as 20” and 24”, are available for smaller riders. These are ideal for smaller riders looking to hit jumps that aren’t quite groomed for a BMX bike.
