A nation's industrial development begins with junior engineers.

Just as Wang Kui had shut down his "old nest".

Everyone looked at the things Jiang Xia had assembled with curiosity on their faces.

Jiangxia welded a cylindrical fuel tank onto the diagonal bar below the main bar.

The 45cc gasoline engine was enclosed by an iron frame and directly connected to the base of the triangle, forming a rigid connection with the original large gear.

The handlebars of both tractors were also replaced.

In short, it was not much different from the modern-day light cavalry, except it was smaller. After all, it was a modified bicycle, but as long as it could run, that was enough.

After Jiangxia started the engine and rode it around for a bit, everyone got excited again.

"Isn't that just a motorcycle?"

"Nonsense! We're not trying to steal the motorcycle factory's business. This is a self-service vehicle! A bicycle that automatically assists in its movement!"

"Besides, our car can only go 18 km/h at most, how can it keep up with other people's 50 or 60 km/h!"

Why rush to make something for my master's wife?

It's cold if I drive too fast!

Bullshit~

Actually, this small engine doesn't have a transmission; it's just that fast once it starts running.

Jiang Xia originally wanted to develop a continuously variable transmission (CVT), but while the cone pulley was easy to make, the steel belt was difficult. With the current technology, even if you replaced the tractor belt with the CVT, it would deform after a couple of uses.

Let's develop it further. After all, starting from nothing and never having anything at all are two different things.

The group of friends all took turns test-riding it and found that the brakes were quite difficult to handle. Luckily, the young man managed to stop it after a while by pushing hard; the brake pads rubbed against the tire for a bit.

Why?

The vehicle does not have brake calipers, or rather, there is no way to install a hydraulic braking system.

Unlike motorcycles, bicycles don't have brake pads. Bicycle wheels are all spokes. If you were to add a whole set of brakes like a motorcycle, you might as well just build a real motorcycle.

Therefore, older people are not suitable.

Ma Zhendong was the first victim of the lack of brake calipers. Unable to stop, he and his vehicle plunged into a sand pile used for firefighting.

Fortunately, he was unharmed and cheerfully climbed out on his own, repeatedly apologizing for his mistake and saying he shouldn't have damaged Jiangxia's prototype.

Jiang Xia realized this wouldn't do. If his master's wife were to fall like that, it would be better not to do it at all!

change!

On one hand, the original bicycle brake pads were widened, and on the other hand, the brake cable and engine were linked. As long as the brake is applied, the engine will close the oil circuit and create neutral.

Although this change makes it resemble the old tractor where you have to restart the engine if it stalls, it's safer, isn't it?

After some repairs and modifications, the "self-service vehicle" finally took shape.

Since it was still early, I helped a few other friends with cars to modify their vehicles, and we agreed to summarize the trial results tomorrow.

I finished making the changes and was ready to leave work.

Jiang Xia picked out a freshly made ordinary pressure cooker and tied it to the back shelf. After getting two exit permits from the security office and recording the reason for leaving in detail, he started the engine and sped away amidst the curious gazes of the security guards.

Hehe, you still have to be careful when moving things home in front of everyone, after all, it's public ownership now.

Even without a leader present, Jiang Xia remained cautious.

I enjoyed the curious glances from passersby and felt like the coolest kid on the block, but eventually I couldn't take it anymore.

cold!

A gust of wind was blowing into my sleeves!

No, no, how can this be allowed for my master's wife to ride!

Don't try to save your energy by freezing yourself.

Jiang Xia had considered making it a closed carriage, but there was no way around it. If there were plastic parts, it would be easier, but now it's all big lumps of iron. If it's made like that, the small engine will have a hard time running it.

What, you're saying PVC already exists?

Ha, these are lab products; large-scale use is still a long way off. Besides, this batch of PVC bags is intended for the logistics department to pack sterile medical kits.

After the Ministry of Chemical Industry delivered it, this was all that was left in stock.

Turning into the alley, he rummaged through the warehouse and found the old school cotton-padded uniforms issued by Wudaokou. He tucked the cuffs directly into the bicycle handlebars, making them look like a windproof blanket from later times. He also took out a "Pleasant Goat" plush toy and tucked it into his chest before continuing on his way.

People should have self-awareness. If you're physically weak, just do some technically demanding work. It's not shameful.

When we arrived at the family compound, the same old soldiers from the night before were having a meal together downstairs again.

But today it seems to have been upgraded; both high-voltage power lines are steaming. There's also a coal stove next to it, with a kettle on top.

Upon closer inspection, oh, it turns out another cable line has been moved out of the adjacent stairwell. No wonder.

Everyone looked on with curiosity at Jiang Xia riding his strange-looking vehicle.

"What have you come up with this time, you little rascal?"

Li Changfu walked over, saw that Jiang Xia still had two big snot drips from her nose, and casually tossed her a handkerchief.

Jiang Xia wiped his face. "It's for my teacher's wife! Don't even think about riding it!"

"Get lost, how do you drive it!"

Li Changfu first took off the pressure cooker tied to his back and handed it to an elderly woman.

He then shooed Jiang Xia off the seat and carefully examined the strange-looking bicycle.

Then, he stretched out his legs and sat down directly on it.

"Where's the accelerator again?"

"No! Pulling the brake once puts it in neutral, pulling it again puts it in gear. The speed is around 18 km/h. If you want to ride, take it easy! After all, you don't have your master's wife's skills!"

Who do you think you are!

Li Changfu slammed on the brakes, "Eh~~ Holy crap~"

It just darted out like that.

Hey, that troublesome old man!

Jiang Xia followed closely behind him. Fortunately, Li Changfu was experienced in such situations, and although he rode crookedly at first, he managed to straighten up.

"Ha! It's nothing! I've driven Japanese cavalry before, why would I be afraid of a little thing like you?" After regaining his balance, Li Changfu turned around and yelled at Jiang Xia, who was running behind him with his tongue lolling out.

"Look! Look! There's someone up ahead!"

There are people there!

And she's the master's wife!

Just as Li Changfu turned around and started yelling at Jiang Xia, his teacher's wife returned on her bicycle.

Li Changfu then rammed his head into his teacher's wife.

Jiang Xia gritted his teeth and sped up his shod legs, trying to rush between the two of them to act as a cushion.

No, it's too late.

~

Jiang Xia closed his eyes, kicked his legs, and threw himself out again.

Seeing her troublesome husband and her dim-witted child both heading straight for her, the teacher's wife sighed.

He dismounted with both legs together, took a step forward, and spread his legs into a horse stance.

First, he cleared the front of the oncoming car, then with his left hand, he pulled Li Changfu out of the car seat.

He held Jiang Xia, who was flying towards him, in his right arm and spun him around a few times.

With another flick of his right foot, he hooked it right under the crossbar of Jiangxia's bicycle. With a little effort, the bicycle lay flat on the ground, with only the rear wheel still moving slowly.

His actions drew shouts of approval from the elderly people nearby.

The master's wife casually tossed Li Changfu into a pile of weeds and helped Jiang Xia stand up.

"This is what you made for me?"

"Yeah! A 45cc small displacement engine, a full tank should be enough to go 60 kilometers!" Jiang Xia shook his head, feeling a little dizzy.

"Wow, that's pretty impressive, let's give it a try!"

With a flick of her long legs, the teacher's wife lifted the bicycle up. Jiang Xia then explained to her how to operate it, and the teacher's wife sputtered away.

Jiang Xia was worried, so he rode his teacher's wife's bicycle and followed them.

Li Changfu looked up at the sky.

With a wife like this, a husband's authority is no longer secure. o(╥﹏╥)o
