A German immigrant to the United States, Ignaz Schwinn, began making bicycles in Chicago in 1895. In 1933, he introduced the balloon tire. It had a separated tube and tire and was a smaller and wider than bicycles tires had been before. Now children could ride bicycles much more easily. Schwinn's sales zoomed from 25,000 bicycles in 1932 in 1936
