In mid-March, the cold in winter has completely faded, and the land that had been frozen because of the cold outside Bangta City began to get hot and humid, and countless green grasses broke through the soil.

At this time, it is a good time to go out, so when there is a good sunny weather, there will be countless aristocratic young masters riding in their own luxury carriages, driving out of Bangta City and facing the green fields outside the city. Progressive.

Today, outside the city of Bangta, it has been surrounded by several straight and flat roads. The western suburbs are all made up of various factories because they are determined by the urban masters to be industrial areas. There are few green spaces left, but the southern suburbs are because of the city owners. The adults were determined to be recreational areas and not only kept the green grass and trees, but also opened a canal to bring in the water of the Sandy River, transforming the southern suburbs, which was originally a wilderness, into a green mountain and green water. There is also a great place for birds and flowers.

Today is a sunny and good day. The sun has just risen in the air. It is the carriage of countless nobility in the city. It drove out of the south gate of Bangta City and headed for a greenery in the south of the city.

Countless noble ladies and young ladies, they are planning to play in the suburbs with this good weather, and host a relaxing and joyful wild feast.

However, today, peace is often different.

In the numerous carriages that rushed out of the city gate, there were two different things.

The young masters on the carriage heard the exclamation outside, and opened the curtains of the carriage. They saw that on the road leading to the southern suburbs, two people were sitting on a wheel consisting of two wheels and an iron bracket. Flat, it looks strange on something.

Two people stepped on the two pedals and kept turning around their wheels as they squatted.

With the disc carousel, the two wheels on the iron shelf kept rolling forward, driving two people to keep on the road.

What surprised everyone was that the strange thing that the two men sat down clearly looked very thin, with nothing but a bracket except for the two wheels. However, it was able to fly forward with the two people above. In an instant, there were more than a few carriages and they ran to the front of many noble ladies.

Watching the two people follow the unknown strange things, they are rushing on the road. Whether it is the noble lady of the carriage, or the pedestrians on the road, they are not allowed to stay.

What exactly is the two people sitting under the ass? How can I run with them so fast?

However, the two people actually disappeared into the distance of the road, so that the questions in the hearts of all people could not be answered.

The next day was another sunny day.

As usual, there are countless carriages driving out of the city gate. Going outside the city.

But at the same morning at nine o'clock, the two weird things once again carried two people out of the city gate, once again surpassed countless carriages and disappeared at the far end of the road.

The doubts in people's minds are deeper.

On the third day, it was sunny again.

The same situation is repeated again.

The fourth day...

The fifth day...

......

It’s a rare sunny day every day for a whole week. Every day, countless noble ladies and young ladies want to go out on a green outing, but every day there are two strange things carrying two people out of the city gate, and then quickly disappear into the eyes of everyone.

The accumulation of seven days in a row made this mysterious strange thing spread throughout the city of Bangta, and it aroused the curiosity of everyone.

Someone who had a good thing had been waiting outside the Nancheng Gate a few days later, and painted the appearance of the two strange things.

After analysis, everyone found out. These two weird things are actually very simple. They are pressed against the ground by two flat tires. They are supported by an iron frame and driven by two gears connected together. Finally, the people above are used. Feeling pedaling as a motivation.

However, the principle seems to be very simple. These two strange things can actually run so fast under the driving force of manpower, which is really incredible.

At the beginning, people didn't know what it was and where it came from. But then the careful people guessed a bit from the two tires.

This kind of tire can only be produced by the Xinfei Chamber of Commerce. Together with the new Feishang Chamber of Commerce, it has always been able to produce all kinds of strange things. These two strange things are very likely to be the newly developed magic machinery of the New Flying Chamber of Commerce!

All doubts and guesses were finally answered on the eighth day. ,

In the early morning of the eighth day, the freshly released "Bangta Daily" finally revealed the answer.

People guessed that these two strange things are indeed the latest products developed by the new Feishang Chamber of Commerce. But unlike everyone's imagination, this thing has nothing to do with magic.

This thing called a bicycle is a kind of manpower machine, driven entirely by humans, without any magic.

But even if it is just human-powered. As long as the person riding the bicycle is strong enough, the speed of the bicycle can still be made fast.

According to the internal news obtained by the Bangta Daily, it is said that the Xinfei Chamber of Commerce will be able to ride the bicycle from Bangta City in the early morning when testing the bicycle. It will be able to reach the rain valley before noon.

It is necessary to know that the Rain Valley and Bangta City are 60 kilometers apart, even if you run the best carriage for more than three hours.

The speed of this bicycle is actually much slower than the best carriage!

Seeing the report of the Bangta Daily, people instantly boiled up.

There is such a good thing, it is much more convenient when you travel later!

Although the carriage is good, raising a horse can't afford it for ordinary families.

Although the urban public transportation system of Bangta City is now gradually established, it can take the carriage to reach most of the places that I want to go, but the carriage is asking for money, not to mention that there are many places where the carriage can't go.

Compared to this simple and lightweight bicycle, the carriage is undoubtedly much more cumbersome.

So after confirming that the bicycle was produced by Xinfei Chamber of Commerce, the door of the new Feishang Chamber of Commerce Product Service Center was instantly crowded by countless people. Countless people ran to ask when the bicycle would start selling. People can't wait to buy one.

"It seems that the sales of this bicycle is not awkward." Xu Yi haha ​​smiled, put down the "Bangta Daily" in his hand, turned to look at the magic machine tool research and development workshop is driven by a wind magic engine, the tire rotates at high speed bicycle.

Strictly speaking, this bicycle is just an accessory that Xu also developed for the development of the engine.

Although bicycles are only a commercial product that is not very important in the light industrial system, bicycles contain many engineering technologies that are extremely important.

Such as power construction, bearing drive, gear castings, etc., a series of technologies that can be applied to many aspects. Will be used in bicycle production.

Xu also let Camby and others develop bicycles. In addition to adding a new product to the new flying company, there are also more experience and theoretical knowledge about these technologies in the development process.

This is very different from the earth.

The mechanical engineers on the earth first learned the theoretical knowledge and then began to practice production.

The mechanical engineers represented by Camby in the Xinfei Chamber of Commerce, under the guidance of Xu Yi, first practice production and then learn theoretical knowledge.

This is also a no-brainer. Xu also wants to accelerate the development of the industrial system. You can only inculcate your theoretical knowledge to them like this.

Fortunately, the dwarves such as Camby are really talented in this respect. Xu is only a little bit to mention, they can understand deeply, and even can give inferences.

By developing bicycles, Camby and others have become mechanical engineers with a deep understanding of dynamic theory.

In the next step, Xu is to let them combine the bicycles that have been developed to a certain degree of wind power magic engine.

If you can recreate a magical engine with a wind-powered magic engine as a driving force. That means that the development of the magic engine can be really used in practice.

The experiment that Campi and others are doing now is a test of the power output stability of the wind-powered magic engine and the bearing strength.

Now this test has been going on for ten days, but the effect has always made Xu not too satisfied.

First of all, the wind engine magic engine can't keep the output all the time, but it will stop without warning, and the output power is sometimes slow and sometimes slow.

After careful examination by Xu Yi and several researchers at the Magic Research Institute, it was found that this was because the wind magic system imprinted inside the engine caused the air flow inside the engine to be disordered because the bearings inside the engine rotated at a high speed. This also has a certain impact on the magic array, which affects the output power.

If this effect accumulates to a certain extent, it will cause the magic array to temporarily lose its effect, thus causing the engine to lose its driving force.

There is also a very important issue, or a material issue.

Bicycle gears and bearings do not have much problem at low speeds, but the loss is greatly increased after maintaining high speed for a long time.

Inferred from the evaluation, if the wind speed magic engine is kept at the highest speed. Whether it is the bearing of a bicycle or the bearing of the engine itself, it is feared that it will take ten hours to produce extremely strong wear and even break.

This little bit is also no way for the time being.

Because this is a material problem, and the material problem is just the most difficult problem in the industrial system.

Although the industrial system on the earth is basically perfect, it has been lagging behind in material technology.

Xu Yi, a mechanical engineer in the Tian Dynasty, is not particularly good at material issues, plus national restrictions. Even less able to master the most advanced material technology.

For this problem, he can only pin his hopes on the materials research institute led by the Slubby Patriarch.

Prior to this, the Institute of Materials, led by the Slubby Patriarch, had given Xu many surprises.

Now Xu will hand over this problem to him, and then wait until the non-ferrous metal veins on the black rice wasteland are mined and smelted. I believe that the Slubby Patriarch will hand over a satisfactory answer to Xu.

Before that, I can only wait patiently.

Even if Xu Yixin is eager to develop the engine, the mechanical technology research and development can not be neglected.

As a genius mechanical engineer on the earth, Xu also has this awareness and also has this patience.
