The Eiffel Tower and bicycles as we use them come from about the same time in history and have a similar look of spindly beauty.

The Eiffel Tower was built in 1889. Safety bicycles, the name of bikes with equal sized tires that everyone could ride as they replaced big wheel little wheel bikes mostly ridden by daring young men, took over between 1880 and 1890.

I can see the beauty of the shape of bikes best on sunny days looking at the shape shadows of parked bikes on the sidewalk.
