Do you know who invented the motorcycle?

American, Sylvester Howard Roper (1823-1896) invented a two-cylinder; steam-engine motorcycle the fuel for it is coal and was invented in the year 1867. This is believed and considered as the first motorcycle, if you allow your description of a motorcycle to incorporate a steam engine. Howard Roper also invented a steam engine car.

German, Gottlieb Daimler introduced the first gas-engine motorcycle in 1885, which had an engine attached to the bike. The bike was made up of wood. This invention was marked in history when the dual development of a feasible gas-powered engine and the modern bicycle collided. Gottlieb Daimler used a new engine invented by engineer, Nicolaus August Otto. Otto invented the first "Four-Stroke Internal-Combustion Engine" in 1876. He called it the "Otto Cycle Engine" As soon as he finished his engine, Daimler (a former Otto employee) built it into a motorcycle.
