Drasiana (1817)
It was the first two-wheeled vehicle arranged in-line, and the first practical human-powered vehicle, was the first reliable claim to practical use of a bicycle, was the first commercial success of two-wheeled, man-machine interaction vehicle. -
Draisienne a pedale 1839
In 1839 Scottish blacksmith Kirkpatrick Macmillan added bar pedals to a prototype. By doing this, he had allowed the rider to propel the was machine with his feet without touching the ground. The drive mechanism consisted of short pedals attached to the rear wheel and connected by bars to the pedals in front of the driver. -
Grand Bi (1870)
In 1870 a plan was devised to resolve the situation with the balance problem. An inventor named James Stanley suggested using the front tire much larger than the rear -
safety bike (1876)
The first "safety" bike to be demominated was designed in 1876 by the English engineer Harry John Laws, on safety bikes the driver's feet are close to the ground, facilitating the maneuver of stopping the vehicle. The pedals were the ones that drive the rear wheel, so the rider's feet stay in a safer place, away from the spokes of the front wheel -
velocipede (1934)
The bisicleta was created in 1934, its most important characteristics were that it had a different weight and stiffness, which determine the efficiency with which the power of the pedal strokes and then later on its wheels. For this effect, the maubrio are placed lower than the saddle to place the rider in a more aerodynamic position. -
The Raleigh Chopper
It was released in Canada June 1969 as a bicycle for children. it was a key factor in reviving the company's earnings. The 3-speed model was made, the shift lever was mounted on the horizontal top tube of the frame, Other differences are the unusual frame, padded seat with long backrest. -
Mountain bike
It is characterized by more resistant components to the impacts of the terrain and for being provided, in many cases, with a suspension system that can be single or double, in addition to single-fork bikes, the tires are thicker and with cleats to absorb better the irregularities of the terrain, and there was an attraction to the public -
recumbent bicycle
The recumbent bicycle is a type of bicycle in which the cyclist adopts a more comfortable position but there was also the more aerodynamic sensation, so that on flat or favorable terrain it is faster than the traditional bicycle. On the climbs what depended on the weight was that the low speeds do not allow him to assert his aerodynamic advantage. -
the great evolution
All these bikes that were presented gave rise to the transport of the human being, they were the transport of the human being from antiquity, they evolved, until they mixed it with technology, which did the human being could advance much more. -
electric bike ("2020")
Today the advances that bicycles present are enormous. Technology didn't make electric bicycles that manage to function as a kind of hybrid between motorcycle and bicycle, but there are several advances in terms of parts such as brakes. Science and technology are also increasingly at the service of cyclists, as there are now biomechanical studies that help determine the suitability of certain elements, such as the seat, height, type and size of the bicycle frame.
