Speaking of bicycle "28 big bars" is our deepest memory. One of the "horizontal bars" was the biggest difficulty for children to learn to ride bicycles at that time, and it also carries many touching moments and romantic memories. However, later these bicycles gradually canceled the "horizontal bar" design. What was the original function of the "horizontal bar" design in ? Why was it gradually cancelled later?

Brief History of Bicycles Crossbar was once the mainstream design

Modern bicycles were first designed by Count Sifrack, France's "Trojan Horse Wheel" and were first introduced to China during the Tongzhi period of the Qing Dynasty. As a rare thing, we went from Shanghai to the Qing Palace. The first bicycle was the Emperor of Guangxu , and then the bicycle developed greatly in China. After the founding of New China, it has become the main means of transportation for the people, with a total of over 100 million! The earliest information of

can be seen that there has been a horizontal bar in the middle since its birth, and later a steering design has been added. After years of use and modification, it is also designed with a horizontal bar. until the introduction of bicycles into my country, the design of the "big crossbar" was also preserved. What are the benefits of such a design?

First, the horizontal bar of the old bicycle is connected to the two support below and combines it into a triangle. triangles are the most stable shape. This design of increases the stability of the car body and is not easy to deform. The strength of the car body has also been enhanced, and allows the car to speed faster. At the same time, such a triangle design also ensures the safe driving of the bicycle on uneven roads.

Secondly, it is the extraordinary load-bearing capacity of cross-bar bicycles in that era. bicycles were introduced to China in the late Qing Dynasty , and in that era there was basically no industrialization in China. The transportation industry is still in a state of "cars, horses, cattle and sheep, shoulders and backs". As a new thing, bicycles are still foreign things that only royal nobles can use. It was not until the founding of New China that domestic enterprises began to manufacture independently that bicycles slowly entered people's lives. In the context of gradually entering the era of industrialization, carrying people and cargo is the most basic need for bicycles as a means of transportation.

horizontal bar design increases the strength and stability of the bicycle body, which naturally greatly enhances the load-bearing capacity of the bicycle. At the same time, the horizontal bar is equivalent to an additional "hanging point" that allows the bicycle to carry more goods or people, and the stable design of the horizontal bar greatly reduces the probability of vehicle damage. The most typical example of widespread use of is the postal "28 big bars" used by postal crew at that time. is basically one car in hand.

The times create heroes, and the times go heroes are old

Since the horizontal bars have strengthened the bicycles with "epic level", why did the bicycles produced later cancel the horizontal bar design? Especially in the new century and even the "shared bicycles" that were developed in a burst of energy, they all had no horizontal bar design? In general, Lian Po is really old!

The reason for the disappearance of the horizontal bar: adapting to the needs of female cycling

As early in the early days of the birth of bicycles, there were bicycles that did not have horizontal bars to adapt to women's use. Friends who have ridden a bicycle know that, especially girls, have a more real experience. Skirts are very preferred by women. If you wear a skirt or shorts, it will be very inconvenient to ride a bicycle. The skirt is relatively short in summer, and it is easy to "exposed" when riding a bicycle. If there is another big bar in the middle, the picture of getting on and getting off is really unimaginable. Skirts are relatively long in autumn and winter, and bicycles with horizontal bars are easily entangled up and down, causing safety hazards. Therefore, bicycles without crossbars came into being, allowing girls to enjoy cycling easily.

horizontal bar disappears reason: upgrade of raw materials

bicycle was originally a wooden body, but later developed into an iron body. In order to give the bicycle body sufficient strength to meet the load requirement. After the founding of the People's Republic of China to the 1990s, the bicycle body produced in China was mainly made of chromium molybdenum steel . This material is relatively bulky and has a longer service life and is prone to oxidation and rust after the paint is removed. This requires the structural increase of the strength and stability of the car body, and the horizontal bar is the best choice. With the advancement of material technology, the strength of steel materials has been greatly enhanced, and many new materials have been added to the manufacturing of bicycle bodies, such as carbon fiber , reinforced engineering plastic , etc. These upgrades to can make the bicycle body light and strong, and no longer need horizontal bars to support it.

horizontal bar disappears reason: More convenient modes of transportation

The main reason for the disappearance of old bicycle horizontal bars is the emergence of more advanced and convenient modes of transportation. With the advancement of science and technology and the improvement of living standards. China has experienced the development process of bicycles to motorcycles to cars and later electric vehicles. The bicycle itself exits the stage of history, and we no longer need it to take on the task of load-loading travel . Later, we advocated green and environmentally friendly travel bicycles and returned to daily life. At this time, the wide and flat roads of do not require crossbars to strengthen the body. Moreover, bicycles do not need to undertake heavy load tasks, but instead develop towards lightness and beauty, and the horizontal bar will naturally disappear.

"28 big bars" Newborn in a foreign country

Although, in China, there are few "28 big bars" with horizontal bar designs. However, Chinese companies found a new place for him. The hardworking African people have made good use of the characteristics of 's "28 Big Bar" with a strong structure and strong load capacity. 5 sacks of carbon and 500 kilograms of bananas can be easily taken! Just like in China in the past, the "28 Big Bars" have now become a very important production tool in Africa.

National sentiment that disappeared with the bicycle bars

In China, old-fashioned bicycles with horizontal bars have basically withdrawn from the stage of history as an important means of transportation. What is left is also a rare "props" type existence. This is the inevitable result of scientific and technological progress and social development. However, the horizontal bars of the old bicycle left us a lot of beautiful impressions. They are found in many literary and artistic works.

Close your eyes and we can recall the first time we rode a bicycle: a short and weak boy, slanted, with one hand on the horizontal bar, and one foot through the horizontal bar. It seems to be hanging on a bicycle, just moving forward tremblingly, stubborn and firm.

We have also seen a couple in love riding together. The bicycle passes through the fields, through the roads in the city and rural areas, through the slight spring breeze, through the hot summer, through the flying autumn leaves, and through the falling snow. The girl sat on the crossbar and snuggled in the boy's arms with a smile. The boy sniffed the fragrance of his long hair and held the handle tightly, warm and happy.

We have seen a determined father with his lover and his children. The mother leaned against the back seat, the younger brother was in her arms, and the older sister sat on the horizontal bar, leaning against her father's broad chest. No matter where the car is heading, even the most advanced car now cannot give us such warmth. Perhaps we have to reproduce such a warm picture, such beautiful memories can only be in dreams.

Conclusion:

Any tool or design will eventually disappear in the long river of history, because the progress of human science and technology has never stopped. In a modern society that is also pursuing convenience and efficiency, large bicycles with horizontal bars, such as the "28 Big Bars", can still make use of their remaining energy in other countries, but they have already withdrawn from the mainstream market in China. The progress of science and technology and society is what everyone expects, and backward tools will inevitably be eliminated. However, the bicycle has too many very beautiful memories for those two or three generations, and it carries too many

Every time I think about it, it makes people cry about family affection and love. As a national sense of responsibility, "horizontal bar" will surely become a classic design and remain in the history of human civilization.
