Bicycle

As written Columbia Encyclopedia, bicycle ancestors are thought to originate from France. According to newspaper history, the country has since the beginning of the 18th century knew the two-wheeled transportation device called velocipede. Over the years, velocipede became the only term that refers to the two-wheel vehicle design.

To be sure, the construction is not familiar with the iron. The model was still very "primitive". Some say no crank, pedal stick steering (handlebars). They say there is already familiar with the crank and handlebars, but the construction of the timber.


Was a German named Baron von Drais Karls Sauerbronn noteworthy as one falsifies velocipede. In 1818, von Sauerbronn make two-wheel transportation to support its work efficiency. As the chief forester Baden, he does need a high mobility transport. However, the developed model seems still ambiguous, between bicycles and horse-drawn carriage. So that people dub the Baron's creation as a dandy horse.Only in 1839, Kirkpatrick MacMillan, a blacksmith born in Scotland, made the"engine" for bicycles. Certainly not a machine like those of motorcycles, but more like a driver who turned the crank, passing up and down movement of the foot pedal. MacMillan also had "dared" to connect the crank had to stick steering (handlebars simple).While noting efforts to improve the encyclopedia Britannica.com French inventor Ernest Michaux in 1855, by making ballast crank up the pace of the bike more stable. The more perfect after the other French, Pierre Lallement (1865) strengthens the wheel by adding a metal ring around it (now known as the rim or wheel). Lallement who also introduced the bicycle with the front wheel is greater than the rear wheels.

But the most significant advance occurred when perforated steel-making technology is found, after getting good iron splicing techniques, as well as the discovery of tire rubber as a raw material. However, safety and comfort factor remains unresolved. Because the technology suspension (per and so on) has not been found, wobble and shake frequently to make their riders back pain. Half jokingly, dubbed the bike Lallement as boneshaker.So do not be surprised if in the era of the 1880s, three-wheeled bicycle that is considered safer for women and men whose legs were too short to ride a conventional bicycle became so popular. Trend two-wheeled bike again after the establishment of a worldwide first bicycle factory in Coventry, England in 1885. James Starley established the plant is found growing momentum after the year 1888 John Dunlop invented the technology of wind tire. The rate of bicycle was no longer shaking.


Other findings, such as brakes, gear ratio which can be changed, chains, handlebars that can be driven, and many more and increase the attractiveness of the bike. Since then, millions of people started to make bicycles as a means of transportation, with the U.S. and Europe as a pioneer. Though slowly, its role began to cut off cars and motorcycles, bicycles still have observer. Even the fans are known to be rabid.
