Youth freestyle bikes are sized depending on the diameter of the wheel staring at 12” all the way through to 18”, at a 20” wheel the bike is considered an adult size. Adult freestyle bikes are sized on top tube length, a 18.5” top tube is extra small for younger teenagers who have just moved up to an adult bike, a 20” top tube is small, mongoose dirt bike 20.5” a medium and anything over a 21” is considered large.
