Roper steam velocipede 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, perhaps most often, known as the "first motorcycle" because there is doubt by some experts that a steam cycle meets the definition of a motorcycle.

Daniel Gooch Gooch was born in Bedlington, Northumberland, the son of John Gooch, an ironfounder, and his wife Anna Longridge. In 1831 his family moved to Tredegar Ironworks, Monmouthshire, South Wales, where his father had accepted a managerial post, and it was there that Daniel would begin training under Thomas Ellis senior, who together with Ironmaster Samuel Homfray and Richard Trevithick pioneered steam railway locomotion.
