In 1885 Gottlieb Daimler combined a bicycle with a gas-powered engine, creating the first motorcycle similar to the modern form. Daimler, however, was just one of many inventors working on similar projects during the same period.
A few decades prior to Daimler's invention, Sylvester H. Roper crafted a bicycle powered by steam. In 1884 a three-wheeled design, also powered by gasoline, was displayed by Edward Butler. By the 1890s, motorcycle improvement and production was on the rise in the United States and across Europe. As companies still in existence today, such as Indian and Harley Davidson, entered the market in the early 1900s, motorcycles steadily increased in power, speed, sturdiness and popularity.
