22"

Hey me and my friend were wondering if there was a 22" unicycle. its seems like that would make a lot of sense as a really good all around uni any input?

Yes there is a 22" Miyata unicycle. However they are not easy to get hold of outside of Japan. Josue Barretto rides one for freestyle.

There are also 14" and 18" unicycles, though I’ve never seen one of these in real life - only pictures.

I’d imagine getting replacement tyres and rims for any of these non-standard wheel sizes would be a major headache.

You can see those unicycles here:
