"Les Velocipeaduses, C'est pas plus difficile que ca, Les Bain de Mer," circa 1870

In the 1860s, French blacksmith Pierre Michaux added a pair of foot pedals to the front axle of a two-wheel velocipede. His breakthrough set the pattern for modern bicycles, though other inventors later developed chain-and-sprocket drives. This print shows two women pedaling their velocipedes in France. Its title roughly translates to English as "The Velocipedists, It's as Simple as That."
