Bicycle laws

I will write the four major theorems of bicycles that I discovered。

  • The law between breads
  • Weight principle
  • The Law of Discovery
  • Countryside signs

The law of pans is a proposition about bicycle punctures and duration。
Between breads
1The air pressure of the bicycle increases as it goes from 5 to 5。
Low air pressure makes it easy to get punctures、You can see that it is difficult to puncture if it is high.。
Especially from 2 to 3 is a sudden change.。
3is normal air pressure,、Even a little deflating increases the risk of punctures。
It is better to air frequently.。

next、The principle of weight is that the force of pedaling a bicycle is proportional to body weight。

$$ F=mα+kv $$

A person weighing 50 kg and a person weighing 100 kg need twice the power to pedal a bicycle.。
Therefore, if you lose weight, you only need to lose weight.。
Air resistance is also important.、The fatter you are, the more surface area you get, so the law applies.。
However、Exercise bikes don't fit this law。

Further the Law of Discovery。
Tire replacement is 6,000 yen、Chain exchange is 7,000 yen、Light replacement is 4,000 yen、Key exchange is 5,000 yen、Brake pad replacement is 2,000 yen.。
Cheap mamachari sells for 12,000 yen。
In terms of the total amount, you can buy 2 Mamachari。
What you mean、It means that you should buy a new cheap bicycle。
It is better to fix and use expensive bicycles。
In my personal opinion, bicycles over 80,000 yen are recommended.。

Finally, there is a sign for the countryside。
In the countryside it is better to run on the sidewalk。
Even in road racers。
Roads are dangerous for cars。

Ride your bicycle with care.。
