Hey all I am looking to get another uni to practice a little Freestyle this winter and I noticed at UDC all the UNIs listed in freestyle are 20" but under 24" they also list a Nimbus X 24" freestyle. So 20" or 24" that is the question?
Actually, I have managed everything on level ten on my 24" unicycle, although I can only land side ride with the transitions about one in a hundred times.
Although you can learn most freestyle tricks on a 24", if you're buying a unicycle specifically for freestyle, a 20" is almost certainly better, unless you're extremely tall.
Since most uni's made for freestyle are 20', most people just buy those if they are looking for a quality 20'. Since I've used a 20' for freestyle my whole life, I never really thought about a 24' being a freestyle uni, or anything else over 20 as a freestyle. I suppose if someone grew up using a 24' as a freestyle uni, then they'd get really good at it. But I think 20' has better control, that's the reason they're more popular.
