Footnotes

• Historians are still unclear with the actual date of its creation. This steam-powered velocipede was built by Sylvester H. Roper of Massachusetts. He would often demonstrate at circuses and fairs. Its power source was a vertical firetube boiler heated by charcoal. Interestingly enough, Roper died of a heart-attack on 1 June 1896, while driving a twin-cylinder creation of this Velocipede at 40 mph on a bicycle track in Boston.
  
  Currently this machine is preserved in the Smithsonian Motorcycle Collection and unavailable to the public.
