Bicycle History

According to one theory, it is said that the first time that Ko hui-seong ran a bicycle in Chang'an street in 1896, and Dr. Seo Jae-pil was the first person to go to the construction site of the Independence Hall in the same year. At this time, people say that they thought the bicycle was a "monster car" or a "carrying bird".

About two years later, in 1898, Yun Chi-ho introduced Hawaii, which is the second time. This bike, which used tires, was very rough, but popular at the time.

This bike, which runs on a bendy road, has become a big story even with the nickname 'the car of the day' or 'the chariot car'.

This was the occasion that gradually came into the crowd, and in the autumn of 1903, the introduction of one hundred bicycles for the officials of the mediation showed that the awareness of the bicycle improved.

Since then, bicycles have increased their use as a means of transportation and as means of transportation. In 1910, the bicycle history of Sangju began to spread bicycles on each side in order to help the efficiency of administration.

At this time, [Raji] and [Fuji] bicycles were mainly supplied.

The size of the bicycle was 28 inches, so it was hard for the Koreans to ride.
* At that time, the price of the bicycle was about 30 won (the price of 10 bananas because it was 3 won for 1 rice bran).

In addition, after returning from studying in the United States around 1928, he was a professor at Severance Medical School, and he used to ride bicycles for leisure activities. Bicycle manufacturing in our country began with the production of components mainly for repair, and production began in earnest in the late 1950s. In 1994, it produced 1,186,400 units, becoming a major producer of bicycles in the world, and the variety of vehicles has also diversified from practical use to leisure use and has been exporting a lot.

Bicycle type

Inspect the plated part from time to time and wipe it with an oil mop.

(Transmission springs, transmission connections, transmission gears, chains)

The place where oil should not be painted - Brake

Things to check before boarding

Is Brake Braking Good?

Whether the handle is fixed

Is the saddle fixed?

The chain is not stuck down

Is the air pressure of the tire appropriate?

Does the back reflector or flicker work properly?

Is the pedal or starboard crank nodding?

Front and rear hub nuts are tight

Is the brake lever working well?

Is there any abnormality in body and fork?

Whether the wheels are well attached or not.

Does the headlight work well

Are the bolts and nuts in each part well assembled?

Precautions for use

Do not apply grease to the surface that touches the wheel. When you lubricate, the brakes do not hear well.

Do not burn in bad conditions such as body, front fork and rim. (Downhill road jumps or overturns, jumps, slopes)

When the pedal shaft or the starboard crank is bent or cracked when it falls, or when the car body is deformed or cracked, it should be checked and exchanged.

After a month of purchase, the screws may be loosened and should be inspected.

Check the brake condition from time to time.

Be sure to wipe it with oil mop after rain or muddy road.

Assembly and coordination of critical parts

Saddle - Saddle should be adjusted so that it touches the ground when you sit down.

Pneumatic - If the tire pressure is too low, it will easily wear out and cause a puncture and heavy rotation. It is suitable for about 5-10cm from the ground when riding.

If the handle height is adjustable, adjust it to fit your body.

The brakes should be checked to ensure that they work at all times and do not lubricate the brake parts. Rapid braking is dangerous. Brake operation takes the rear brake first and catches the front brake later. If you suddenly catch the front brake, you can fall down. If the brake rubber is worn, replace it with a new one. Ensure that the brake wire is tightened firmly.

Transmission

The left transmission is the front wheel --- the right transmission activates the rear wheel

The lower the number of gearboxes, the lower the speed, used for sloping roads.

The higher the number of transmissions, the higher the speed and the higher the level.

The transmission always checks that the wire is loose.

Tighten the adjustment bolt of the shift lever when the chain falls automatically after shifting.

Do not operate the transmission at a stop

Depressing the pedal depresses momentarily.

Rear blinking of the headlights is necessary for safety at night. The headlights should be adjusted so that they can be seen 10 meters ahead.

Quick Release Hub It is a quick release that makes it easy to remove and assemble the wheel axle (hub).
