Bicycle Face
In the 19th century, doctors came up with a lame medical condition known as Bicycle Face to discourage women from cycling. The idea was that they would scare them by making them believe that riding a bike would cause their chins to jut out because of the strain to stay balanced on the bikes. A secondary side effect of bicycling was bulging of the eyes. Oddly enough, they claimed this condition only affected women and not men. But some women saw through the ruse and kept on riding.
