BICYCLE
Bicycleis a friendly
transportation.Bicycle consisting of handlebars, seat and a pair of
foot-powered paddle to move. Estimate bicycle from the French.
The construction was still not familiar with the iron and the shape is still primitive.
Karls Drais Baron Von Sauerbronn, is complement bicycle model. he made two wheeled transportation to support its work efficiency. But he invented the bicycle model is similar to the train.
From year to year, the bike continues to be developed. in 1885 Ernest Michanx make crank weights so that the rate is more stable bike.
The most significant progress occurred during hollow steel making technology to find and more advanced lengthening techniques as well and the discovery of iron as a raw material rubber tyre. But, safety and comfort factors remain unresolved. Because the technology suspension (spring and so on) has not been found, wobble and shake often make their riders back pain. Half jokingly, dubbed the bicycle Lallement as boneshaker.
So don’t be surprised if in the era of the 1880s, three wheeled bicycles are 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 factories are increasingly found momentum after 1888, John Dunlop tire technology to find the wind. The rate of bicycle was no longer shaking.
Other findings, such as brakes, gear
ratio which can be changed, chains, handlebars that can be moved, and many more
bikes appeal more to add. Since then, millions of people started to make
bicycles as a means of transportation, with America and Europe as a pioneer.
Though slowly, its role began to cut off cars and motorcycles, bicycles still
have observer. Even the notoriously rabid fans.
