Bicycles are not technically difficult.

The core point lies in the gears and chains, and the most technical part is a manual braking system.

When the technical difficulty is negligible, the rest is a matter of materials.

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

However, to make it a qualified product, it is not enough just to be able to make it.

We also need to consider the user experience, safety issues, cost and market.

This all needs to be studied bit by bit.

The first thing is to decide 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 gear, the shock absorption of the seat cushion, the center of gravity of the cyclist during riding...

One large item splits into more than twenty sub-items that require attention.

Many sub-items can only be left undecided due to lack of on-site inspections.

There are also some sub-items that, due to lack of data support, can only temporarily calculate a set of formulas, waiting to be embedded with actual usage data.

Chu Tianshu spent about half an hour to solve all the sub-items that could be solved so far. Then he found a soft ruler, measured his height, and nested it into the integrated data.

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

What problems should Chu Tianshu solve before bringing this business to Qi Yingzhi?

For people like Qi Yingzhi who have begun to get in touch with practical matters and have made certain achievements, raising these problems and solving them one by one is actually a better way to demonstrate their own value and integrity than coming up with a novel project.

capable.

But when you make a sample individually, you don’t need to think so much.

You only need to embed your own data into it and make the actual object, and that's it.

Chu Tianshu took the token given by Qi Zhongliu, took all the money he could use, put on the pocket watch given by Qi Yingzhi, and walked out of Prince Chen's Mansion alone for the second time.

After leaving the palace, Chu Tianshu was not in a hurry to buy various materials and start making bicycles.

He first bought two plain boxes, and while eating them, he talked with the old man selling fried boxes.

The old man's name is Chen Kun. He is fifty-four this year. He has two sons. One son is now working as a foreman in a textile factory, and the other opened a small shop selling grain and oil. The two sons have given the old man three grandsons and four granddaughters.

"Being a leader in the factory is a big deal." Chu Tianshu exclaimed, "Why don't you get only three to five yuan a month?"

"Hey, there are so many of them. They only cost two and eighty-five cents in the factory."

"Don't pay taxes?"

"We pay taxes in the factory. What taxes do those who receive wages pay?" The old man still felt that Chu Tianshu was dizzy.

"That's right. If you pay taxes in the factory, then what taxes should those who receive wages pay?"

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

"It's normal to set up a stall and open a shop and pay taxes. Now you're your own boss!" Chu Tianshu smiled.

"Alas." The old man sighed: "Who says it's not the case? But I always feel that setting up a stall is not as good as working in a factory. I work so hard every day, and most of them have to be handed over to the court. Setting up a stall

, but it’s more like working for the imperial court.”

In the blink of an eye, the complaint phase has entered.

The person selling roasted sweet potatoes next to him also started complaining.

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

As he walked further and further into the muddy road that looked like a slum, Chu Tianshu first found a tavern, sat down and ordered some special turbid wine, and followed the drinkers in the tavern to brag about how he had done something in a certain year.

There was an opportunity to make a fortune in Yue, but he didn't seize it, and said that he met a beautiful girl in a certain month of a certain year.

After chatting for a long time, the topic turned to iron prices.

An ordinary iron hoe costs about seven cents per unit and weighs about half a catty, which is 750 grams.

The price of ordinary wrought iron from the steel factory is about two cents.

It is said that there are many models and specifications of steel, and the price is generally 5 cents or more.

Relatively speaking, it is quite expensive.

Then, Chu Tianshu walked around randomly in the market.

While learning about the prices of various commodities, I also observed the heights of the people I met.

Taking Chu Tianshu's own height as a benchmark, among the 127 people he met, only 11 were obviously taller than him, 25 were about the same height as him, and the rest were

, are all lower than him.

And those who are shorter than him are generally much shorter than him.

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

There are not even many people with medium and plump figures.

Chu Tianshu made a preliminary basic judgment in his mind.

Of course, this still requires further observation.

Moreover, the sampling environment of the currently investigated samples 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 observed today would not be the first consumers of bicycles.

Really, if we want to build bicycles and develop them as an industry, the first target customers should be the group of students in the school, and those who have a little money but are not very rich, but are used to seeing bicycles.

The bookboys and maids who live in a scene of wealth and status and claim to be superior people.

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

After Chu Tianshu observed and investigated, he asked for directions and headed to a nearby steel plant.

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

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

After a while, the factory got off work, and one after another, workers from the steel factory poured into the pub to drink and relieve their fatigue.

However, most of them did not like Chu Tianshu who asked for a bottle of wine and two side dishes to sit and drink. Instead, they stood in front of the counter and spent 30 cents for a bowl of wine.

Occasionally, if you pay an extra penny, you can get two extra slices of fatty pork belly, which you can eat with wine.

"Zizi." Chu Tianshu drank a glass of wine, held up a pair of chopsticks to eat hot dog meat, and listened carefully to the curses of the iron factory workers in front of the counter.

"Fuck you, I'm working overtime again. It's almost the end of the month, and it's Yuanwang Festival. I don't even talk about giving some rice to eat. I just increase the amount and ask the men to work overtime. These sons of bitches."

"His mother!" The worker took off his work clothes and wiped the sweat on his head with the sleeves of his work clothes: "I don't know what shit the foreman ate today, and he scolded me again, saying that grandpa didn't pay attention to his work.

, said I was lazy."

"I really want to punch him."
