I am not sure why, but when we went to the Henry Ford Museum (which is great!) yesterday I was shocked to learn that the bicycle was invented in the 1800's and that they were wooden, foot powered contraptions with no steering.
I was even more surprised when I found out peddles weren't added until the 1860's, and that it wasn't until the 1870's that a British engineer made the first "efficient" (meaning rideable) bicycle called the "Penny Farthing."
The museum has a huge collection of bicycles and early motorcycles. This bicycle built for two to ride side by side was my favorite (although I am pretty sure it'd be tough to balance).
And this one with a wooden frame and handle bars came in a close second.
