Bailiyun pointed to a wooden bicycle and said: "This two-wheeled one is called a bicycle, as the name suggests, it is a car that walks on its own." Of course, this requires a little motivation from www.biquge.info the user. I'll show you! ”

Bai Liyun said, pulled the bicycle and rode up, his yard was very large, enough for him to perform. Liu Sansan and the three of them watched Bailiyun ride this wooden mechanism and move quickly by himself, going straight, turning, fancy, very relaxed.

Bailiyun rode two laps and asked, "How is it?" Let's do it! ”

The three of them were dumbfounded, who would have thought that a wooden thing could act so quickly!

However, Xiao Liu is a mechanic in the end, and he has excellent professional skills, so he didn't return his skills to the master. He still saw some doorways, after all, many things are the same, although the appearance is different, but he knows that the principle can be reversed quickly.

Xiao Liu dragged his chin and said, "Well, yes, I didn't expect to be able to use the trick like this, it's really a wonderful idea!" There have been similar things in the past, but they are all war equipment, and the size is too large, we haven't studied this aspect, which is very valuable for reference and gives me a lot of inspiration! ”

"Young master, you should have used a gear transmission method!"

Bailiyun said to Xiao Liu: "Yes, draw inferences, you can see the way so quickly, Xiaomo, your tricks are still okay!" ”

Xiao Liu smiled and said, "The young master has won the award, compared to you, I am really nothing to be a wild man!" ”

Bai Liyun encouraged: "Don't laugh at yourself, you still have a lot of advantages." You must know that the technique depends on the person, it is difficult to say that it is difficult, and it will not take long to become a teacher if it is easy. The most important thing is to have a good eye for subtle observation and a smart brain that is very responsive, and everything else is external. ”

looked at Xiao Liu's body and said, "Maybe it has something to do with your work as a tomb robber and your excellent skills, now you have good eyesight, and your brain reaction is okay, at least not stupid." As a mechanic, you have all the basics. What you lack is nothing more than a solid knowledge of the orthodox theory of mechanics and plenty of physical objects for you to practice! ”

Speaking of this, Bailiyun said proudly: "And these are exactly what I can give you." So, study hard, in my place, as long as you work hard, are willing to fight, and dare to work hard, sooner or later, you will show your skills in Datang and bloom your own light! ”

Xiao Liu thought longingly, and then said solemnly: "Young master, I know, I will find the dawn that belongs to me!" ”

Bailiyun waved his hand, pointed to the bicycle and said, "Okay, let me introduce you to this bicycle!" ”

Xiaoliu nodded yes.

Bai Liyun introduced: "As you can see, this bicycle is actually no different from the previous mechanism, but the method applied is different from the previous one. The first is the beam frame, which supports the entire body as well as the user. ”

"Then there's the wheels, which connect the bike to the ground. The wheels are okay, mainly the bearings in the middle, which must be made of iron, and lubricated with oil, which is also a top priority. Because it is different from the traditional cart, this is used for a long time to travel quickly, if there is no good bearing, it is completely unable to support the weight of the human body and the power potential energy generated after action, oh, maybe you don't understand what I said, but you know the meaning, and I will slowly hand over the specific things to you later. ”

"By the way, there are also plastic products wrapped around the outside of the wheel, after the rubber products are dried, there is a great elasticity, which can reduce the shock of the user, and can also speed up to a certain extent, because it will make the grip stronger, reduce the useless work generated when the wheel is not forced."

"Then there's the chains and gears. Due to the difference in the mode of movement, it was not possible to use the conduction force between the gears, and it was changed to a chain gap occlusion gear to drive the rotation. ”

"And, of course, there are brakes, which are very thin, so it costs a little more to manufacture. This is used to stop the wheels from turning. Of course, if you're confident that your feet can withstand the damage, you can also use the foot brake! Hahahaha! Speaking of the brakes, Bai Liyun couldn't help but quip.

It's a pity that the three people opposite him are not modern people, and they don't understand at all, Liu Ruhui is even more worried about whether Bailiyun drank too much last night and his brain is not sober, thinking about whether he should ask someone to make a bowl of sobering soup for him to drink for a while, after all, she is now the housekeeper of the inner mansion in Baili Mansion, and taking care of the young master is the most basic thing.

Seeing the three of them looking at each other, he remembered that most of these three people would not understand the fun brought by the foot brake, that is, he had just told a cold joke that no one could understand.

Bailiyun was a little embarrassed, thought about it, and in order to prevent himself from becoming the pioneer of Datang's cold jokes, he personally went into battle and demonstrated it with his actions on a bicycle. In order to make them distinguish, the handbrake was also demonstrated.

When Bailiyun stepped on the earth and made a mark on the land, the three people who were not weak in understanding finally understood the profound meaning of the foot brake.

In an instant, Liu Ruhui couldn't help but be happy.

Xiao Liu wanted to laugh, but Bailiyun was the master, so he still held back, but the red face still betrayed him.

Liu San smiled slightly and shook his head helplessly. Secretly, the young master is really too young, as the master, how can he do such a gaffe in front of his subordinates, it seems that he will have to supervise it well in the future, this is not what a nobleman should do. But, really, hehehe! Bai Liyun looked at the expressions of the three of them and nodded with satisfaction, sure enough, I am not a person who tells cold jokes.

But soon he broke out in a cold sweat, because he thought, what if my shoes were worn out just now? It's a question worth pondering.

Fortunately, Bailiyun's shoes are wear-free day-hunting boots, he is used to wearing these shoes, and he will not change his shoes easily. Otherwise, there will be a big joke today, hehe!

In order to avoid embarrassment, Bailiyun changed his words and said: "Well, by the way, in addition to the above, there are also handlebars, which control the direction, and there are also car seats, as well as the back seat that can put things and be a person." That's what the bike, of course, is wooden. ”

Xiao Liu asked at the right time, "Young Master, is there any difference between the iron ones?" ”

Bai Liyun nodded and replied: "Yes, in order to use it better, of course, it is also to increase the value of iron bicycles." The iron bike has the same overall shape, but the wheels will change from solid to rims with spokes and bearings. The back seat will also become a form that can clamp things. In addition, there will be an iron bell on the handlebar to alert pedestrians in the distance. And because it is iron, it will be much better in quality and more durable. And it is also more suitable for transformation, and some small parts will be added in the future to adapt to the preferences of high-end consumers. ”

Cloth shoes foot brake, very feeling! Everyone, I recommend a collection to reward, thank you!
