I am relatively new to unicycling and have recently learned to ride and do very small jumps on my Torker 24" unicycle. I am struggling to do other skills and am considering purchasing a 20" wheel to put on my 24" unicycle. I read that 20" wheel is better for tricks. I am aware that the 20" wheel will make it harder to balance, but I was wondering if anyone has tried what I am considering.
Also, if this is a bad idea, does anyone have any recommendations for a better unicycle? I would like to use it for tricks, but I don’t want to spend more than 300 dollars.
so you are willing to spend 300 though??
if so…you might as well be willing to just go ahead and get a nimbus 20" + kh cranks for $330. a very strong unicycle thats perfect for what you wanna be doing. and…no a 20 inch unicycle is easier to control. ultimate wheels get harder as they get smaller : )
What sort of tricks are you wanting to do? Trials? Freestyle? you’ll want a totally different type of unicycle for either.
I think I want to do more freestyle. So you think putting a 20" wheel on my 24" in unicycle is a bad idea, and I should just purchase a new one?
yeah especially if you’re gonna do freestyle…
A 20" wheel will not be harder to balance. You can replace the wheel, but without having to change out the crank arms each time you do this (a major hassle + wear & tear), you’re really buying almost an entire new unicycle. All that’s left is frame, post and seat. So generally it’s better to save up for a whole different unicycle. Then you’ll have two! One to share, or one each for the types of riding you want to do, without needing tools & time to switch wheels.
Otherwise, the only downside of a 20" wheel in a 24" frame is a high crown, which will make some tricks a hassle, and more advanced tricks much harder. But Miyata used to use the same frames for their 20" and 24" unicycles, and we managed to do pretty well on those… 
The rate at which people respond is ridiculously great. Thanks a lot!
