The Roper steam velocipede was a steam-powered velocipede built by inventor Sylvester H. Roper of Roxbury, Boston, Massachusetts, United States sometime from 1867–1869. It is one of three machines which have been called the first motorcycle, along with the Michaux-Perreaux steam velocipede, also dated 1867–1869, and the 1885 Daimler Reitwagen. Historians disagree over whether the Roper or the Michaux-Perreaux came first. Though the Reitwagen came many years later than the two steam cycles, it is often labeled as the "first motorcycle" because there is doubt by some experts whether a steam cycle should meet the definition of a motorcycle.
