More then 30 years ago, my dad tried to teach me how to ride a bicycle. He'd fixed a broomstick to my bicycle to  hold me upright while I was balancing my bike. 

Soon however, my dad gave up running behind the bike and he replaced the broomstick with to small wheels on either side of the bicycle. The small wheels, stayed on till I felt confident enough to ride without.

The story has nothing to do with unimotorcycles.

But 30 years on, dad and bike both have known better times, but the idea to mount small wheels on a bike seems very alive.

So if you're not confident enough to trie out unimotorcycle racing, these people may be able to overcome your initial fear : www.ononewheel.com
