A unicycle is one of those things that I consider a worthy endeavor to learn if you are into that. I got one long ago and learned to ride it (barely), there is some sense of accomplishment to that. I still take it out every few years, air it up, and ride it just to prove to myself I still can. I grew up in the third world, so I never had one of those kiddie trikes. The unicycle was the technically the first fixed gear I owned.

I say go for it.
