Okay, okay.  I know this goes against the unicycle principle, but I do actually ride bikes (I'm better on my uni).
I also ride pogo sticks and stuff.

Here are some pictures.

Oh, yeah.  No-handed pogo stick riding.  I'm good.  I find that with unicycling it helped my balance greatly, which makes it easier to ride a  pogo stick.  And no, I didn't fall in this shot.

This is one of my bikes.  I have another full size one, but this sure is more fun.  It is exactly like a regular bike, but really small.  This is the Huffy Monkey bike, Hear No Evil.
