History of Motorcycle
Replica of the 1885 Daimler-Maybach Reitwagen

Motorcycle history begins in the second half of the 19th century. Motorcycles are descended from the "safety bicycle," a bicycle with front and rear wheels of the same size and a pedal crank mechanism to drive the rear wheel.

Despite some early landmarks in its development, motorcycles lack a rigid pedigree that can be traced back to a single idea or machine. Instead, the idea seems to have occurred to numerous engineers and inventors around Europe more-or-less simultaneously.

Early milestones

An 1894 Hildebrand & Wolfmüller



Petroleum power
The inspiration for the earliest dirt bike, and arguably the first motorcycle, was designed and built by the German inventors Gottlieb Daimler and Wilhelm Maybach in Bad Cannstatt (since 1905 a city district of Stuttgart) in 1885. The first petroleum-powered vehicle, it was essentially a motorized bicycle, although the inventors called their invention the Reitwagen ("riding car"). They had not set out to create a vehicle form but to build a simple carriage for the engine, which was the focus of their endeavours.


Steam power
However, if one counts two wheels with steam propulsion as being a motorcycle, then the first one may have been American. One such machine was demonstrated at fairs and circuses in the eastern United States in 1867, built by Sylvester Howard Roper of Roxbury, Massachusetts.There exists an example of a Roper machine dating from 1869, but there is no patent existing and nothing proves it was a working model. It was powered by a charcoal-fired two-cylinder engine, whose connecting rods directly drive a crank on the rear wheel. The Roper machine pre-dates the invention of the safety bicycle by many years, so its chassis is based on the "boneshaker" bike.

In 1868, the French engineer Louis-Guillaume Perreaux patented a similar steam-powered vehicle, which was probably invented independent of Roper's. In this case, although a patent exists that is dated 1868, nothing indicates the invention had been operable before 1871. Nevertheless, these steam-powered vehicles were invented prior to the first petroleum-powered motorcycle.

First commercial products
In the decade from the late 1880s, dozens of designs and machines emerged, particularly in France, Germany and England, and soon spread to America. During this early period of motorcycle history, there were many manufacturers since bicycle makers were adapting their designs for the new internal combustion engine.

In 1894, the Hildebrand & Wolfmüller became the first motorcycle available to the public for purchase. However, only a few hundred examples of this motorcycle were ever built. Soon, as the engines became more powerful and designs outgrew the bicycle origins, the number of motorcycle-oriented producers increased.

The first known motorcycle in the United States was said to be brought to New York by a French circus performer, in 1895. It weighed about 200 lb (91 kg) and was capable of 40 mph (64 km/h) on a level surface.[4] However, that same year, American inventor E.J. Pennington demonstrated a motorcycle of his own design in Milwaukee. Pennington claimed his machine was capable of a speed of 58 mph, and is credited with inventing the term "motor cycle" to describe his machine.
