in p>1876, Otto, a German, invented the gasoline engine, which provided a power source for the development of motorcycles. Daimler improved on it. In 1885, he put an improved gasoline engine on a two-wheeled vehicle, and made the world's first motorcycle driven by gasoline engine, named "Single Track", with a speed of 12 km/h. In the same year, we obtained the patent and the invention priority. Daimler used the German word "motoweirad" in his invention, which was gradually accepted and widely circulated in Germany. The meaning of this word is "machine-driven two-wheeled vehicle". Later, people used to say "motorcycle" as "motorad" and omitted "raweira".
