The first thing to do before entering fully into the establishment of the meaning of the term bicycle, is to know its etymological origin. In this case, we can determine that it is the result of the sum of three components:
-The Latin prefix “bi-”, which is equivalent to “two”.
-The Greek word “kyklos”, which can be translated as “wheel”.
-The French diminutive “-ette”.
It is known as bike to the means of transport that has two wheels, with pedals that allow movement to be transmitted to the rear wheel through a chain, a pinion and a plate. It is a vehicle that moves by the propulsion of the user, who must pedal.
At a general level it can be said that the picture (the structure) of a bicycle integrates two wheels, which are usually the same size and are located in a line; a seat or saddle; a handle or handlebar to guide the address; and a transmission system with pedals.
The cyclist, with his legs, must move the pedals, which are linked to a chain. This chain makes the pinion rotate and, simultaneously, rotate the wheel behind. As the rear wheel rotates on the surface, the mechanism causes the front wheel to also rotate and causes the bicycle, therefore, to roll.
Although its origins are remote, the modern bicycle began to develop in the first decades of the XIX century. In 1839 the first bicycle with pedals emerged and almost half a century later the model of transmission chain.
Bicycles are used as conveyance in urban and rural settings. Are ecological (they do not emit contamination), sustainable (its energy comes from the user himself) and healthy (When using it, the person performs physical activity). They are also very economical since they do not carry any type of fuel and have almost no maintenance costs.
If more and more people are betting on traveling by bicycle around the city, it is not only because of the amount of advantages it brings with it for the environment but for their own health. In the latter case, we can determine that the healthy benefits it brings are the following:
-Helps to reduce blood cholesterol levels.
-It allows the person who moves by bicycle to improve considerably his coordination at the motor level.
-Increases lung capacity.
-It is considered that, in addition, it tones the muscles.
-It goes without saying that another great advantage of moving by bicycle is that it significantly improves the functioning of the cardiovascular system.
-In this list of benefits we cannot forget either that it contributes to clearly reducing the levels of stress that may be experienced.
-Of course, it is a way to be able to have weight under control and, therefore, to avoid the risks of being overweight or obese.
-It is considered that it contributes to improving emotional health.
