Hello I am a 14 year old kid and I'm 5.3 ft tall. First of all will the onza fit me rite? Also I learn fast, I have a unicycle, and MTB that i can hop and do long wheelies on. I've herd that it's for beginners though. But I don't wanna spend money fast and do it again when I become better. So I have herd people also upgrade them, so please tell me what upgrades I'd be looking at prettie soon? Also with the price please.
