> Nonetheless, most people have never actually seen a bicycle.

This is culture specific. In The Netherlands, kids see bicycles as they grow up. They see children going to elementary school on them, they see them after school, they're an important part of our culture and in large cities they're practically everywhere. Heck, I got brought to kindergarten on... a bicycle. You can be sure as hell any kid of age 4 or higher has seen a bicycle (4 is the age they enter elementary school). In the Catholic area of NL, its very much a tradition that after communion the child gets their own bicycle. IIRC that's around 7 or 8 years. Whether kids (from NL, of whatever age) can draw a bicycle is a different matter, I cannot judge on that one.
