For example, a carpenter who makes bicycle handlebars only makes bicycle handlebars.

In this way, practice makes perfect, and you can quickly increase your speed by making just one thing.

Those who make wheels specialize in making wheels, and those who forge bicycle frames specialize in forging bicycle frames.

Each step of the process involved building a huge factory with hundreds or even thousands of people constantly making their respective parts.

Finally, all the parts are gathered together and assembled by workers in an assembly workshop.

Just one week later, the assembly line factory that Zhu Yuanzhang had planned was fully completed in the east of the capital.

And the factory's name is: Bicycle Manufacturing Plant!

Once the factory is fully operational, it will be able to produce thousands or even tens of thousands of bicycles every day.

After these bicycles leave the factory, they undergo quality inspection. Once it is confirmed that there are no problems, a serial number is engraved on the bicycle's gears.

In this way, even if the bicycle is lost in the future, it can be found by its serial number, and no one can tamper with, erase, or cover up the serial number on the gear.

Once such a system is in place, it can also prevent this important private property from being stolen.

Although the bicycle factory can produce thousands or tens of thousands of bicycles every day, it can only barely meet the market demand in the capital.

There are probably hundreds of thousands, even millions, of people living in the capital.

The majority of them could afford bicycles, and the remaining group, although not wealthy, could afford them with a little effort and ten or fifteen days' wages.

Therefore, Zhu Yunwen predicted that among the hundreds of thousands of people in the capital, at least each family might own one or two bicycles or tricycles.

The demand would then be two to three hundred thousand bicycles or tricycles.

Such a huge market cannot be satisfied in a short period of time, even with the factory's astonishing manufacturing speed.

That's not all; markets in other regions have not yet been explored.

However, other markets must also be thriving, because after seeing the bicycles owned by people in the capital, word of it quickly spread among the people of other counties near the capital.

Many local residents also came to the capital to queue up and pay deposits to snap up bicycles and tricycles.

In this way, after a month, the demand for bicycles in the entire capital city was finally met.

It is even gradually approaching saturation.

The resulting change was that the Ming Dynasty's fiscal revenue increased by a large sum of money.

Each bicycle cost 500 coins, and a total of 400,000 bicycles were sold within a month, generating a total of 200,000 taels of silver.

A tricycle was worth 1,000 cash, or one tael of silver. Two hundred thousand tricycles were sold, totaling two hundred thousand taels of silver.

Therefore, within this month, the sale of bicycles and tricycles alone added 400,000 taels of silver to the national treasury.

After deducting costs, labor fees, and Zhao Qingzhu's management fees, 350,000 taels of silver still went into the national treasury.

Such a way of increasing national revenue is simply terrifying, even somewhat conservative.

Moreover, the car market in Beijing has only temporarily reached a saturation point.

However, this sales volume will likely be maintained gradually in the future.

Because bicycles and tricycles are consumable products.

It will eventually break down due to wear and tear after six months or a year.

If only some parts are broken, you can go to the store to buy the corresponding parts and replace them.

If the entire vehicle is broken and can no longer be ridden, then you need to buy a new one.

Therefore, it's conceivable that this is a long-term business.

The production speed in the factory still needs to be increased. However, after reaching a saturation point in the capital, the demand has decreased. Finally, some other bicycles can be transported in batches to other parts of the Ming Dynasty.

When Zhu Yunwen thought about transporting bicycles and tricycles to all parts of the country, he decided to further improve the tricycles by replacing the seating area in the back with several planks for transporting goods.

Of course, since this vehicle still requires a person to operate it, such a cargo tricycle cannot carry too much cargo.

As long as it's convenient and simple to transport a portion of the goods, that's acceptable.

So when this product was first launched, its price was the same as that of a three-wheeled vehicle.

This thing is still popular with the people because it is very convenient for those who set up stalls.

Goods can be placed on it, and the electric tricycle can be moved around freely, eliminating the hassle of pushing a cart as before.

For some business people, using these three-wheeled trucks to transport goods is also particularly convenient.

After all, the roads in the Ming Dynasty are in very good condition now, and it's incredibly easy for business people to transport goods from one city to another.
