Until now, a better means of transport has not been created , it has all the necessary characteristics to move from one point to another more efficiently, ecologically, economically and without producing noise pollution.
A clear example of the good use of bicycles is Amsterdam, where there are more than 600 thousand bicycles for 750 thousand inhabitants . Other Norwegian cities like Bergen give us the possibility to take a bicycle for a coin in a certain place and return it in another place. This great ideal was also adopted in cities such as London, Seville, Barcelona and Paris, surely many others will follow this example, since by means of the bicycle two major inconveniences that arise in cities these days can be solved: the lack of space and the contamination.
Undoubtedly, when Leonardo da Vinci , in 1490, made his first conceptual record in one of his drawings (found in the Atlantic Code ), he did not imagine the scope or acceptance that his idea would have.
Three centuries later Earl Mede de Sivrac created a device that he called ‘ Celerifer’ , it was a wooden structure with two wheels that to move it had to be pushed with your feet on the floor.
In 1816 Karl Christian Ludwing Drais unveiled the ‘ Draisienne’ , similar to the previous one but adding a handlebar to it. As time went by, Ernest Michaux put the pedals on him. In 186, metal structures appeared and by 1888 Boyd Dunlop began marketing pneumatic tires. At the end of the 19th century, a pinion was added to the wheel by means of a steel chain with which the transmission problem was solved.
Since then, the market for bicycles has been growing around the world, entering its production in China, Vietman and Taiwan. The models have changed as well as the material with which they manufacture . By times the models, preferences and fashions were varying. Today one of the models that is sold the most in mountain bikes and a model in which this mountain bike is combined with a more urban option but not less strong for that.
At the beginning its structure was made of wood, then metal and now the ideal material has gone from being an aluminum hydroforming that, through a pressurized water process, allows the manufacture of tubes that can be adapted to all needs.
Another advance is the use of carbon fiber plates, which is a highly resistant material with very low weight . Since aluminum and fiber can be changed, in some cases both materials are used, the metal front and the carbon rear, which gives the wheel a lot of flexibility.
With an eye on the future, they plan to incorporate electronic technology and how could it be otherwise in Japan they are already manufacturing transmitters and special components for city bicycles.
