I just don't see how it can really be compared to a bike just because it has a single wheel and you can ride on it. If I take a ab roller and figure out some way to balance my weight on it and ride around, you wouldn't call it a unicycle.
I might be wrong but what is it classified under? Is it a bike...I never actually knew this.
