Chapter 283 (1/2)

The development of bicycle is much smoother than expected.

What bothered Donne most before was the production technology of tires and bearings. However, one of these two technical problems was solved long ago, and the other was successfully solved by the technical team led by Nokia.

The bearing processing technology has long been applied in dwarf engineering. Ball bearings have been widely used in their previously restored semi-finished steam battle tanks. The production technology has been available, but the processing technology is not high.

The problem of processing technology has also been successfully solved with the addition of Donne. The original millimeter level processing technology has been instantly improved to the micron level, and the precision has been improved by nearly a thousand times, which has increased the service life and efficiency of the bearing many times.

The tire production process has also been successfully completed by the witty dwarfs. These little guys who love to study are always full of extremely positive attitudes towards new technologies and new things. I'm afraid they are at least big cattle with the title of academicians on the earth.

Of course, the appearance of tires is not just for bicycles. The first benefit is Ellington's carriage. After they saw the stability and speed of the carriage in the Lord's house after refitting the tires, the door of Datang Engineering Research Institute was crowded with people who asked to refit the carriage the next day.

The refitted carriage did not disappoint them, whether it was shock-absorbing spring or rubber cushion, or new bearings and tires. After these things were installed, the carriage was like a new look and completely changed.

The original stiff trembling became soft and gentle. Even the pothole gravel road was comfortable. I don't know how many times. What excited them most was running on the asphalt road, and the speed was at least 50% higher than before! Due to the improvement of bearing technology, the friction and resistance become smaller, and the consumption of horses becomes smaller. Therefore, the transportation speed and distance per unit time have been greatly improved, and the forage consumed by horses has been greatly reduced!

It means that the cost of refitting the carriage can be recovered after several transportation, and the rest is to enjoy various benefits brought by the new technology.

Under this stimulus, Ellington has a trend of chasing new technology.

A few days later, bicycles began to appear in the streets of Ellington.

The first batch of bicycles were not sold, but directly digested internally. They were allocated to personnel who needed to run back and forth to convey messages and transport light objects - of course, it was not easy to teach them to ride bicycles.

It's OK for adults to say that they have a strong sense of autonomy. With a little training, they can quickly master the secrets, but children

”Woo - big brother, don't let go -”

Elia clung to the car handle and begged Donne not to let go.

”Trust me, I've been holding on behind you. Just ride.”

Donne constantly encourages Elia to use the same set of bicycles that parents on earth use to teach bicycles

”I, I know... I'll try...”

Fiona, who was riding by not far away, saw this scene with a complex face.

If I had known this, I might as well pretend to be stupid

After the first bike went offline, Donne tried it, and then Fiona wanted to try it. Donne laughed at her that she couldn't. as a result, Fiona was angry, learned to ride in minutes, and proudly showed off to Elsa and Tina.

Now after seeing Donne teach Elia to ride a bike, Fiona finds herself a complete fool.

Win face and lose life

The emergence of bicycles has greatly ignited the enthusiasm of Ellington residents. It is the first time for them to see this purely mechanical transportation tool - what? carriage? Sorry, the carriage also needs to be pulled by horses

Just two wheels, chains and pedals, after ingenious combination, can move forward at a very fast speed, and can master the direction by themselves. It's not too convenient to travel in a short distance!

Especially when the tire is moving forward on the asphalt road, it's so smooth and comfortable that you can control it yourself. It's really cool!

Therefore, after the second batch of bicycles went offline, there was a rush to buy them in Ellington immediately.

The price of a bicycle is only ten gold coins.

what? Too expensive!?

Then you must be a slacker!
