History of Motorcycle

Motorcycle Petroleum power

The earliest inspiration is 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.
An 1894 Hildebrand & Wolfmüller

First commercial products



An 1894 Hildebra 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. 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.

The Safety bicycle

In Wikipedia, the safety bicycle had definied a type of bicycle that became very popular beginning in the late 1880s. The first safety, using a diamond frame, was invented by John Kemp Starley in 1885. "Safeties" are characterized by having two wheels of identical - or nearly identical - size, and a chain-driven rear wheel.

The safety bicycle was a big improvement on the previous penny-farthing design which it replaced. The chain drive, coupling a large front cog (the chainring) to a small rear cog (the sprocket) to multiply the revolutions of the pedals, allowed for much smaller wheels, and replaced the need for the large, directly pedaled front wheel of the "penny-farthing" or "high ordinary". The smaller wheel gave a harder ride, thus hastening the replacement of solid tires with pneumatic ones.

With the center of gravity low and between the wheels, rather than high and near the front hub, the Safety greatly diminished the danger of "taking a header" or long fall over the handlebars. This made braking more effective and cycling, previously the reserve of spry, daring young men, safer, and therefore much more popular, especially for women. The same basic design of bicycle is still in common use today.
