Bicycles used to be a means of transportation that affected the lives of hundreds of millions of people, and in China in the eighties and nineties, when cars and motorcycles were not so popular, almost everyone had a bicycle, which was not lower than the current mobile phone penetration rate. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 infoWang Tao had four bicycles in his family of four when he was a child in his previous life, but when he graduated from college, he didn't have one and was replaced by two electric cars.

The structure of the bicycle is not complicated, the complex is the process and raw materials involved, not to mention anything else, only the rubber tires are not available in the current Ming Dynasty. Not to mention the brake device, but Wang Tao once rode an old-fashioned bicycle, and the pedal was braked, but now it is not easy for Daming to make a chain. Wang Tao's bike is in the style of an old-fashioned children's tricycle, with the pedals and the bearings of the front wheels connected together.

Horse-drawn carriages have been invented for thousands of years, and the production of bearings is also very mature, of course, these are all wooden bearings. Although there are such and such problems, it has also been used for more than 1,000 years, the technology is mature, and the requirements of the model are certainly not so high.

When Zhu Youxiao watched Wang Tao assemble the parts one by one and finally assemble them into a bicycle, and then walked forward with both hands and feet simulating the bicycle model, he could also think that this thing really saves manpower.

"Master Wang's car is really ingenious, but people won't fall when they ride on it?" Zhu Youxiao first praised it, and then questioned.

"No, this bike won't fall when you ride it." Wang Tao didn't know why the bicycle didn't fall, the aerodynamics were too complicated, not to mention that he didn't understand, even if he understood and told Zhu Youxiao, he couldn't understand it.

"Solo riding is just the simplest application, if you add a two-wheeled car in the back, you can also pull some goods with little weight, which can save a lot of manpower." Wang Tao didn't want to continue to talk to Zhu Youxiao about why it didn't fall, and instead talked about other uses.

Zhu Youxiao heard Wang Tao say this, and instantly forgot why the car didn't fall, Wang Tao said that if it can be realized, it can really liberate a lot of manpower and material resources, and he finally understood how Wang Tao's wooden work is related to the people of Limin.

"This is really a fairy method, how long does it take Master Wang to build such a car?" Zhu Youxiao asked about the production cycle of bicycles.

"If it's three or two craftsmen, I'm afraid I won't be able to make one in ten days, but if it's twenty or thirty craftsmen, I can make two or three cars a day. Divide the various parts of this car to different craftsmen to do, all the parts are of the same size, and finally install it. "In fact, the division of labor and cooperation in China has existed since ancient times, and the Qin Dynasty unified the six countries, and the standardized production of weapons also played a great role.

"In that case, I'll mobilize a group of craftsmen, let's make a few to try first." Zhu Youxiao looked at the bicycle as if he had seen a child with a novel toy, and he couldn't wait to see the real thing of the bicycle immediately.

"Send this thing to the Inner Officials and Supervisors to take a good look at it, and tomorrow we will send twenty skilled craftsmen here to listen to the order." When giving orders, Zhu Youxiao's face was serious, according to the words in the novel, with the majesty of a superior.

The little eunuch carefully picked up the bicycle model and went to deliver the decree.

"Your Majesty, I wonder if the construction bureau in the palace can make steel balls?" Wang Tao didn't know the craftsmanship of the Ming Dynasty, so he could only ask.

If you can make steel balls, then you can use the ball bearings of old-fashioned bicycles, so that the axle will have much less wear and friction, and it will be easier to ride.

"Steel balls? Of course there is no problem. Regarding Wang Tao's question, Zhu Youxiao didn't think it was strange, after all, Master Wang was from the upper realm, and it was understandable that he didn't know the situation of Daming.

Knowing that there was no problem with the steel ball, Wang Tao asked several other things in a row: springs, gears, and screws, all of which are not problems, but the names are different, such as springs, which are called collapses (handle plus a collapse, I don't know how to read them). The gear is called a runner.

The emperor saw that the things Wang Tao asked were becoming more and more peculiar, so he simply called the skilled craftsmen of the construction bureau, and Wang Tao kept proposing parts one by one. In the end, Wang Tao found that the only problem now is the tires, which is no way, and rubber is now only available in South America.

It was discussed until very late, Wang Tao finally got a satisfactory answer, and in the end, even if the bicycle can't make much, the use of bearings alone can greatly improve the long-distance transportation industry.

This is just an appetizer, what really moves Wang Tao is the improvement of ordnance. The current firearms are not as good as those of later generations said, but they are not backward compared to the firearms of the same era, as long as they are slightly modified, more advanced guns can be made, and the threat to the Northeast is the most important thing to solve first. Without the threat of the Northeast, at least the country can reduce taxes, and people can buy some corn, potatoes, and sweet potato seeds, which can solve the food problem. Once the internal and external stability is stabilized, shipbuilding technology is restored, and there is now a lot of uncultivated land overseas.

In the next few days, Wang Tao soaked together with Zhu Youxiao and a group of craftsmen to build bicycles, and as the parts were built, Zhu Youxiao's face was full of satisfied smiles. He found that he could be happy even if he didn't have to work as a carpenter.

Finally, six days later, a modern bicycle appeared, except for the leather-covered wheels, of course.

Due to Wang Tao, an expert in bicycle repair, the development of bicycles has taken many detours, and everything is the mature structure that will be hundreds of years later. Although Wang Tao doesn't know why he uses this structure, he just needs to know that this structure is reasonable.

Looking at the bicycle parked there, Zhu Youxiao was eager to try, but neither Wei Zhongxian nor the Ke clan were willing to let him take this risk, and no one believed that this thing could be ridden until he saw it with his own eyes.

The test rider is, of course, Wang Tao's invention, ahem, plagiarist. Today, he specially wore pants that made people special for the future, and he also made straps to tie his legs and feet. The bike didn't have a tether, and he didn't want his trousers to get caught in the chain.

On the car, Wang Tao did not use the chic pedals to lift his legs to get on the car, but first straddled the saddle. Place your left foot on the pedal and your right foot on the ground. Taking a deep breath, Wang Tao had never thought that riding a bicycle would be so nervous, he was more excited than the first time he drove in his previous life, you must know that this is going to go down in history.

The left foot kicked hard, and at the same time the right foot left the ground, and the bike moved a little crookedly. There are no rubber tires, and there is no soft gold from the last life, and the shock absorption of this car does check a little, but riding is not a problem.

Everyone saw Wang Tao riding the bicycle, the speed was getting faster and faster, and the car was no longer crooked, when Wang Tao successfully turned back, Zhu Youxiao's face was flushed, as if he had drunk a few catties of wine.

"Haha, we succeeded, we made the bike!" Zhu Youxiao finally couldn't help laughing out loud and shouted proudly, he had already called this newly invented car a bicycle like Wang Tao.
