Bicycle law in the United States is the law of the United States that regulates the use of bicycles. Although bicycle law is a relatively new specialty within the law, first appearing in the late 1980s, its roots date back to the 1880s and 1890s, when cyclists were using the courts to assert a legal right to use the roads. In 1895, George B. Clementson, an American attorney, wrote The Road Rights and Liabilities of Wheelmen, the first book on bicycle law, in which he discussed the seminal cases of the 1880s and 1890s, which were financed by Albert Pope of Columbia Bicycles, and through which cyclists gained the right to the road.
