I'll be honest--the 1950s were a rough time for cycling.

Shark attacking a bike at the beach in Avon NJ. Don't know what the contraption is on the back of the bike...? Something to hold a big box or a buncha books?

If you just had a wheel, it would roll until it the forward motion was no longer strong enough to keep it upright. Now just add a frame and an additional wheel and now you know why a riderless bike can stay up with forward momentum. Then you have the question of which way will it go...and you get into chaos theory.
