| No single time or person can be identified with the
invention of the bicycle. Its earliest known forebears were called velocipedes,
and included many types of human-powered vehicles. One of these, the scooter-like
dandy horse, of the French Comte de Sivrac, dating to 1790, was long cited
as the earliest bicycle. Most bicycle historians now believe that these
hobby-horses with no steering mechanism probably never existed, but were
instead made up by Louis Baudry de Saunier, a 19th-century French bicycle
historian.A smartly dressed couple seated on an 1886 "bicycle"
for two.The most likely originator of the bicycle is German Baron Karl von
Drais, who rode his 1816 machine while collecting taxes from his tenants.
He patented his draisine, a number of which still exist, including one at
the Paleis het Loo museum in Apeldoorn, the Netherlands. These were pushbikes,
powered by the action of the rider's feet pushing against the ground. Scottish
blacksmith Kirkpatrick MacMillan shares creative credit with von Drais for
adding a treadle drive mechanism, in 1840, that enabled the rider to lift
his feet off the ground while driving the rear wheel. However, some reports
describe MacMillan's vehicle as more of a "quadricycle".
In the 1850s and 1860s, Frenchman Ernest Michaux and his pupil Pierre Lallement took bicycle design in a different direction, placing pedals on an enlarged front wheel. Their creation, which came to be called the "Boneshaker", featured a heavy steel frame on which they mounted wooden wheels with iron tires. Lallement emigrated to America, where he recorded a patent on his bicycle in 1866. The Boneshaker was further refined by James Starley in the 1870s. He mounted the seat more squarely over the pedals, so that the rider could push more firmly, and further enlarged the front wheel to increase the potential for speed. With tires of solid rubber, his machine became known as the ordinary. British cyclists likened the disparity in size of the two wheels to their coinage, nicknaming it the penny-farthing. The primitive bicycles of this generation were difficult to ride, and the high seat and poor weight distribution made for dangerous falls.The subsequent dwarf ordinary addressed some of these faults, by adding some kind of gearing, reducing the front wheel diameter and setting the seat further back with no loss of speed. However, having to both pedal and steer via the front wheel remained a problem. Starley's nephew, J. K. Starley, J. H. Lawson, and Shergold solved this problem by introducing the chain and producing rear-wheel drive. These models were known as dwarf safeties, or safety bicycles, for their lower seat height and better weight distribution. Starley's 1885 Rover is usually described as the first recognisably modern bicycle. Soon the seat tube was added, creating the double-triangle, diamond frame of the modern bike. Successful early bicycle manufacturers included Englishman Frank Bowden and German builder Ignaz Schwinn. Bowden started the Raleigh company in Nottingham in the 1890s, and soon was producing some 30,000 bicycles a year. Schwinn emigrated to the United States, where he founded his similarly successful company in Chicago in 1895. Schwinn bicycles soon featured widened tires and spring-cushioned, padded seats, sacrificing some efficiency for increased comfort. Facilitated by connections between European nations and their overseas colonies, European-style bicycles were soon available worldwide. By the mid-20th century bicycles had become the primary means of transportation for millions of people around the globe. index page1 page2 page3 page4 page5 beauty tips pharmacy product informationveterinary science forum historical houses information |
