I make a popular science video and all the emperors learn from it!

Chapter 168

Bicycles are still a popular means of transportation in modern times.

As soon as it appeared, it shocked the ancients!

Qin Dynasty.

Ying Zheng was puzzled.

He really couldn't figure it out. Two wheels were cut off from the four-wheeled carriage, leaving only two wheels, but the two wheels were still connected to a wooden stick.

A car with such a structure is not stable even if it is left standing. How can it be moved safely?

I really couldn't figure it out. In the end, Ying Zheng simply gave up thinking and recruited people from the Mo family.

"Fan Xiliang, a member of the Mohist family, has met His Majesty."

When Ying Zheng heard this, he swept towards the man in the lead.

He found out that it was the man who helped Da Qin make paper before!

And because of his meritorious service, he was also made a marquis.

Ying Zheng didn't waste any words and said directly:"Fan Aiqing, come and do it for you. I made the bicycle mentioned above"

"Let’s start with the simplest wooden horse wheel"

"yes! His Majesty! Fan Xiliang agreed, looked up at the pictures on the screen, and immediately started working with a few people.

The structure of the wooden horse wheel is very simple.

It was made in half an hour.

Ying Zheng looked around the wooden horse wheel and murmured:"This thing moves forward by pushing on the ground with its two feet. Who will give it a try?"

"Father, let me come!"

Hu Hai yelled and came to him.

He had already become interested in bicycles, so he would have the opportunity to volunteer directly.

"Okay, be careful"

"Don't worry, father, my son is smart."Hu Hai sat on the wooden horse wheel, exerted force with his feet, and rushed forward ten feet in an instant!

Ying Zheng was a little surprised in his eyes.

Hu Hai's feet just left the ground, but the wooden horse wheel did not fall over.

It was obviously very stable.

He seemed to be running faster and faster The faster 913 is, the more stable it is.

In order to confirm his thoughts, Ying Zheng shouted:"Faster, Hai'er"

"okay! Father, take care of yourself."

Hu Hai laughed heartlessly, kicking his feet back crazily, just like the scene of a child playing with a twist car. However, because there was no steering or braking function, when he was about to hit the city wall,

Hu Hai could only use his foot brake!

Ying Zheng pondered for a while and then ordered to his side:"Fan Aiqing, continue to perfect this thing and do your best."

After a short observation, he had already seen the potential of the bicycle.

During the Three Kingdoms period.

Liu Bei looked delighted and looked at Zhuge Liang aside.

"Military advisor, I wonder if you can make this thing? Zhuge

Liang waved the feather fan in his hand and replied:"My lord, this thing can be made simpler. Liang has no idea how to improve it in the future.""

"Okay, let’s make it and take a look."Liu Bei was not discouraged.

It didn't take long.

A simple version of the bicycle was released.

It had a steering device, a bicycle stand, and the rest was no different from a wooden horse wheel.

"Who will give it a try?"

Zhuge Liang looked at Liu Bei for advice.

Several people present looked at each other.

"It all depends on what Guan does!"Guan Yu blushed and was a little angry.

Could he be allowed to ride such a thing and wield the Qinglong Yanyue Sword!?

Thinking about that scene makes me feel funny....

Ming Dynasty.

Zhu Di looked surprised.

Just ordered people to build rickshaws.

Now here comes another bicycle...

No matter how you look at it, bicycles have more development prospects than rickshaws.

After all, the former has 200 million vehicles in China!

At its peak, there were only a few thousand rickshaws.

When Zhu Di was about to speak, he asked someone to make a bicycle first.

A pop-up window popped up on the light screen!

【Q&A session!】

【How many accessories should a qualified bicycle have? 】(To read exciting novels, go to Feilu Novel Network!)

【Option one: three】

【Option two: six】

【Option three: ten】

【Option four: sixteen】

【Option five: Twenty-five. 】

Zhu Di opened his eyes slightly and quickly scanned the questions and answers.

"Option five!"

【correct answer】

【Congratulations to Ming Dynasty Zhu Di for successfully answering the question and receiving: an ordinary bicycle and a bicycle design drawing. 】

The next second.

Two rewards appeared in front of him.

Zhu Di looked at the blue metal bicycle in a daze. Only then did he understand why such a gadget could use so many parts.

The structure is countless times more complicated than a carriage!

Moreover, it is almost entirely forged from metal, making it far more difficult to manufacture than using wood (adfa).

Zhu Di sat on it himself and experienced it[]

"Yes, what kind of material is this cushion made of? It’s so soft."

"Hey, there's something under the seat cushion..."

He looked at the spring, lost in thought.

Then he looked at the wheels of the bicycle. Sure enough, they were made of materials he had never seen before.

At this time, the light curtain is still popular in science

【bicycle exercise:】

【Cycling is one of the best tools for overcoming heart problems】

【More than half of the people in the world die from heart disease】

【Cycling not only compresses the blood flow with the movement of the legs and pumps the blood back to the heart from the ends of the blood vessels, but it actually strengthens the microvascular tissue at the same time. This is called"incidental circulation". Strengthening the blood vessels can protect you from the threat of age. eternal youth】

【In addition, habitual cycling can gradually expand your heart】

【Otherwise, the blood vessels will become thinner and thinner, and the heart will deteriorate more and more. In your later years, you will experience the troubles it brings. At that time, you will find how perfect cycling is.】

【Cycling is a sport that requires a lot of oxygen. An old man once completed a 460-kilometer cycling trip in 6 days.】

【He said:"Older people should exercise at least three times a week to strengthen the heart and restore normal function. You want to make the heart beat vigorously, but not for too long. This way it will be able to adapt to emergency situations, such as catching a car or resisting a difficult situation."】

【Cycling can also prevent high blood pressure and is sometimes more effective than medication.】

【It can also prevent obesity, hardening of blood vessels, and make bones strong】

【Cycling eliminates the need for medication to stay healthy and does no harm】

【Bicycles are a tool for losing weight. According to statistics, a 75-kilogram person can lose half a kilogram of weight by riding 73 miles at a speed of 9 and a half miles per hour, but he must persist every day.】

【Cycling can not only lose weight, but also make your figure more symmetrical and attractive.】

【That is, people who exercise to lose weight, or who exercise while dieting, have better and more attractive figures than those who only rely on dieting to lose weight.】

【Proper exercise can secrete a hormone that makes you cheerful and happy. From experience, we know that cycling can produce this hormone.】

【In fact, because cycling compresses blood vessels, blood circulation accelerates, and the brain takes in more oxygen, so you breathe in more fresh air.】

【After riding for a while, you will feel that your brain is clearer】

【Riding a two-wheeled bicycle that relies on your own strength will make you feel very free and enjoyable.】

【It is not only a weight loss exercise, but also an exile of spiritual joy.】

【In addition, the sport of cycling is also very meaningful】

【...】

A smile appeared on Zhu Di's face.

Cycling has so many benefits!

Prevent heart disease, high blood pressure, lose weight, make people's minds clearer, and make people feel better!

Arrangements must be made for the overweight Zhu Gaochi!

Let him lose weight on his body.

At the same time, when he is bored, he can also ride his bicycle around the imperial city twice.

There happened to be a ready-made bicycle in front of me, and there were drawings, so I could try to mass-produce it in the future.
