Read the passage.

For women living in North America in the 1800s, transportation options were few. In the late 1880s, however, bicycles started appearing in the United States. At first, only men rode bicycles. Female riders were considered unladylike. Gradually, the idea of women riding bikes became more accepted. Female bike riders became a common sight on city streets and country roads. The new sport changed women's fashions. For example, some women traded their heavy skirts for loose pants called bloomers. Women could travel independently from one place to another on their bicycles. They no longer had to rely on men for transportation. In addition, women enjoyed the exercise and fresh air provided by an outing on a bicycle. The well-known suffragist, Susan B. Anthony, claimed that bicycling had "done more to emancipate women than anything else in the world."
