Bicycles are not technically difficult.

The core point lies in the gears and chains. In addition, the hardest technical content is a manual brake system.

When the technical difficulty is negligible, the rest is material problems.

However, with today's technical level, Chu Tianshu feels that it is not difficult to make a bicycle.

However, it is far from enough to make it a qualified product.

We must also consider user experience, safety issues, cost and market.

This all needs to be studied little by little.

The first thing is to determine the size of the bicycle based on the current height of people.

The diameter of the wheel hub, the length of the chain, the size of the gears, the shock absorption of the seat cushion, the center of gravity of the cyclist during riding...

A large item splits out more than twenty children that need attention.

Many children can only stay undecided because of the lack of field investigation.

There are also some sub-items, because they lack data support, can only temporarily calculate a set of formulas and wait for the actual usage data to be embedded.

Chu Tianshu spent about half an hour to solve all the children that can be solved at present, then found a soft ruler, measured his height, and nested it into the integrated data.

——The sub-items under the bicycle project are mostly problems that need to be solved when considering bicycles as a commercial project.

What problems should Chu Tianshu solve before taking this business to Qi Yingzhi.

For those like Qi Yingzhi who have already started to come into contact with practical things and have made certain achievements, raising these problems and solving them one by one is actually better able to show their own value and ability than coming up with a novel project.

If you make a sample separately, you don’t need to consider so many things.

Just embed your own data and make the real thing out.

Chu Tianshu took the token given by Qi Zhongliu, brought all the money he could use in his hand, put on the pocket watch rewarded by Qi Yingzhi, and walked out of the Chen Palace alone for the second time.

After leaving the palace, Chu Tianshu did not rush to buy various materials and started making bicycles.

He first bought two vegetarian boxes, and while eating, he talked to the old man selling fried boxes.

The old man is named Chen Kun, who is fifty-four this year, and two sons. One son is now working as the foreman in a textile factory, and the other one opens a small shop selling grain and oil. The two sons have three grandsons and four granddaughters for the old man.

"It's amazing to be a leader in the factory." Chu Tianshu exclaimed: "Why don't you have to get three or five dollars that month?"

"Hey, there are so many there, the factory only costs two or eighty cents."

“Don’t pay taxes?”

"The factory pays taxes, what taxes do those who receive their wages pay?" The old man felt that Chu Tianshu was dizzy.

"That's right, the factory pays taxes, what taxes do those who receive their wages pay?"

"My boss doesn't pay taxes, but I set up a stall here and have to pay taxes."

"It is normal to set up a stall and open a store, pay taxes. You are the boss yourself!" Chu Tianshu smiled.

"Oh." The old man sighed: "Who said no? But he always feels that setting up a stall is better than working in a factory. He worked hard every day to touch a few, and most of them had to be handed over to the court. If he set up a stall, it was more like working for the court."

In a blink of an eye, the complaining stage has entered.

The roasted sweet potatoes on the side also complained.

Chu Tianshu finished eating the box, complained a few times, and then left.

The more he walked, he walked into the muddy road that seemed like a slum, Chu Tianshu first found a tavern, sat down and asked for some special turbid wine, and followed the people drinking in the tavern to brag, saying that he had a chance to make a fortune in a certain year and month, but he didn't catch it, and said that he met a beautiful girl in a certain year and month.

After chatting for a long time, I brought the topic to the iron price.

The unit price of a general iron hoe is about seven cents and weighs about half a pound, which is 750 grams.

The average cooked iron produced in the steel mill is about two cents.

It is said that steel has many models and specifications, and the price is generally up to five minutes.

Relatively speaking, it is still relatively expensive.

Then, Chu Tianshu walked around the market.

While understanding the prices of various products, we observe the height of the person we meet.

If Chu Tianshu's own height is the benchmark, among the 127 people he encountered, there were only eleven people who were obviously taller than him, twenty-five people who were about the same height as him, and the rest were all lower than him.

And these people who are lower than him are generally much lower than him.

In terms of body size, I don't seem to have encountered anyone who is particularly fat.

Even those with medium and plump figures can’t see many.

Chu Tianshu made a preliminary basic judgment in his heart.

Of course, this still needs further observation.

Moreover, the sampling environment of the samples currently investigated is too single.

People in the market will not be the main consumers of bicycles in the early stages.

In other words, the people he is observing today will not be the first consumers of bicycles.

If you really want to make bicycles and want to lay them out as an industry, the first target customer should be the group of students in the school, and they are a little money but not very rich, but are used to the wealthy scenes and claim to be the best.

The goals examined today can only be used as a data reference for the long-term outlook.

After Chu Tianshu observed and investigated, he asked for the way and headed to the nearby steel factory.

When he arrived at the steel factory, it was the evening when the factory was about to get off work.

Chu Tianshu sat down in a tavern near the steel factory, ordered turbid wine and small cold dishes, and sat down slowly to drink.

Not long after, after get off work in the factory, workers from the steel mill flocked to the tavern to drink to relieve their fatigue.

However, most of them did not ask for a pot of wine and two side dishes like Chu Tianshu, but stood in front of the counter and spent three millimeters to ask for a bowl of wine.

Occasionally, I see that I can give you one more piece of pork belly, and eat it with wine.

"Sizi." Chu Tianshu drank a glass of wine, raised a chopstick of fire dog meat, and listened carefully to the iron factory workers in front of the counter.

"My mother worked overtime a few more times. It's the end of the month. On the Yuanwang Festival, I didn't say I could give some Chu Mi to eat, but I just knew how to increase the amount and asked the man to work overtime. This group of bitches raised it."

"His mother!" The worker took off the work clothes and wiped the sweat beads on his head with the sleeves of the work clothes: "I don't know what shit the foreman ate today, and scolded him again, saying that his grandfather was not attentive to work, and said that I was lazy."

"I really want to punch him."

Chu Tianshu held the wine cup and felt that the atmosphere had arrived: "Then give him a punch."
