"Cluck, cluck, cluck......"

Along the way, there were strings of children's laughter like silver bells.

"Baby, you're still laughing, our father and daughter have become an existence that no one cares about."

Yang Qiao, chatting with his daughter in the back carriage, pedaled the tricycle at the same time, and on the side of the road, there were many people watching the excitement, one by one, they were not afraid of the cold.

All in all, the appearance of this bicycle is a strange scene, what kind of car is this, it is not pulled by a horse, it can walk, look at the person in front, it seems to be walking, but he did not touch the ground, is this a fairy, no, this is Yang Langjun.

Now, near the door of home, or near Yong'an Fang, there is no one who doesn't know Yang Qiao.

However, no one cares what kind of art Yang Qiao is talking about.

No one cares, Yang Qiao did something wrong, and even forgot that the two concubines had children, the old lady was very unhappy, and the two daughters-in-law were also very unhappy, no, these days, every day, Lian's daughter-in-law threw her daughter to Yang Qiao, and went to do her own thing.

What is she doing?

Teahouse, Lian's daughter-in-law, actually opened a teahouse in Dongshi, a teahouse dedicated to entertaining female guests, not to mention, such an elegant thing, there are really a lot of people coming, naturally, the main ones are those princesses, what old princesses, young princesses, princesses who are not princesses, all come, there are also daughters of noble families, ladies or something.

Although, the two concubines gave birth to babies, and Yang Qiao did not arrive, but the two concubines did not have any opinions.

These are two hard-working girls, naturally they understand Yang Qiao, and Yang Qiao is not slow to treat them, can they not understand.

However, Wei Ye girl was a little unhappy, why, she gave birth to a daughter, and Lian'er girl gave birth to a boy.

Well, in the old lady's place, the treatment is different again.

The old lady naturally has to look down on her son, so this Lian'er's treatment is higher, and she is even going to give this kid a full moon or something.

However, Yang Qiao didn't agree, yes, don't be too big, sons and daughters have to live, it's just a small gathering of the family, in the end, this identity is here, Yang Qiao, I don't want to challenge some questions about etiquette, besides, like Yang Qiao's family, there are really not many people with two wives and two concubines, and even, even one concubine, there are very few, this Tang Dynasty woman, after all, still has some status, but unfortunately, the era in which they were born is not successful, this is an era after war, few men and many women, not to mention young women, I don't know how many widows there are, widows and men?

Almost all of them died in battle.

Just look at the age of the old lady, some people are just in their twenties, they are widows, but it seems, how do you feel, more than forty!

However, these are not things that Yang Qiao can solve, but it is still okay to give them a job, and they can't be too anxious, and the work is not so easy to arrange.

And now, Yang Qiao's main job is to play with his daughter, and to test the strength of the bicycle, and what are the shortcomings, but this is winter, so there is a shed on the back of the carriage, and even Yang Qiao is also in the shed, on all sides, there are glass inlaid windows, so that the baby can see the outside scene while sitting.

And the little sister was envious on the side riding a horse, following the walk, and the warm embrace of the eldest brother finally left her.

"Well, yes, yes, this tire, in the snow, also has an anti-skid function!"

Well, chatter has been a little silent lately, so Yang Qiao can only boast now, or say that he is talking teasingly, and in his ears, there is less chatter, as if he feels a little bit less.

However, what is this tire made of, this is a relatively novel, no need to inflate the tire, it is said, in fact, Yang Qiao has already had a draft, that is, to use Eucommia ulmoides glue to make tires, but this Eucommia ulmoides tree, still need to be planted first, and now I can get some Eucommia, but even a tire can not be made.

Therefore, he used animal tendons interspersed and woven to use them as tires, but he didn't expect that this effect could be regarded as leverage.

However, if you want to say that this shock absorption effect is still Yang Qiao's shock absorption system.

Shock absorption? Spring?

At present, Yang Qiao does not have the ability to make a more durable spring, you know, this spring, is not simply the use of elasticity, but also needs durability, especially for bicycles, in fact, in later generations, some ordinary bicycles, there is no spring shock absorption, that is, tire shock absorption.

However, since the talker asked Yang Qiao to use that excavator technology, the shock absorption should also be done.

What kind of shock absorption does it look like?

That is naturally hydraulic shock absorption, perhaps, some people think, this shock absorption, isn't it more complicated?

Wrong, this is not complicated at all, the difficult thing is only the anastomosis and sealing, so it seems that it is a little simple, but it takes time to grind.

There is also an explosion-proof piece, however, this is easy to say, the material is not good, the thickness is matched, and it is perfectly solved.

Similarly, this gear is still not manufactured, this chain drive, it is actually driven by pulleys, and this belt is made of cowhide, and this cowhide conveyor belt is used in another special treatment, that is, this belt will not be elastic, and it is a perfect solution.

The most important thing is the braking system!

Brake?

Well, no matter what time the load-bearing vehicle, the brakes, are very important, this bicycle, whether it is with a chain, or with a wheel drive, the same, there is a fear of breaking, so, the brake, need to be perfectly solved, since it is a tricycle, then, it is necessary to brake the rear wheel, and it is two rear wheels, Yang Qiao uses the rim friction braking system, which is a perfect solution.

However, everything is perfect because one thing is not perfect.

"This monster is good, you see, it can fit two people!"

Two people, this is less, my bicycle, at least, can hold 500 pounds of weight.

Yang Qiao thought triumphantly, in the future, it will be much more convenient for you people.

"This monster must be very expensive!"

is worthy of being a resident of Dachang'an, although he talks about monsters, but he thinks of practicality.

How much money, naturally, the less the better.

"Boy, you can't sell this car, at least, it costs more than two dollars, in fact, even if it is two dollars, you will sell at a loss, but you will return a capital, not counting labor."

Eventually, the chatter began to talk more.

Why, it's so expensive, isn't it a rich man's toy again?

"Why is it so expensive, think about it yourself, axle sleeve, how much do you use, this is copper, how much copper money can be made, this frame, that is iron, this iron, the money is not low, the tire, it is cowhide, and this leather, or the best place, the price is not low, and the hydraulic oil, which you make with soybean oil, although this is not used much, the value is not low, this shed, I can give it to you, you calculate it yourself."

Come on, this has become a toy.

"However, boy, after my scanning, in the vicinity of Chang'an City, or in the city, some small traders, and even, some relatively wealthy households, can still afford to buy, they can't afford ox carts and carriages, you can still afford this bicycle, naturally, the ox cart, the carriage is with oxen, with horses, just a car, the price is still not expensive."

"It's done, don't comfort me, even if someone wants to buy it, temporarily, there is no sale, this is a toy, there are so three or five cars, but if it is mass-produced, it is estimated that it will take a long time, this, I don't worry about it, in fact, things have been arranged, planting eucommia, machining, have their arrangements, I, I am the shopkeeper again, when the time comes, I just point out some problems."

Yang Qiao said casually.

"Boy, you know what I admire about you, it's that you don't care about anything, and what's the matter, start, tired for a few days, and then, it's very idle."

"How am I idle, you see, I'm playing with my daughter now, baby, not tired."

"Giggle, cluck, Daddy, good, good."

As soon as her daughter heard Yang Qiao's call, she stood up, hugged Yang Qiao's neck, and giggled.
