1. Simple version:
1. After each ride, wipe the chain clean with a rag.
2. Before each ride, pump up air (a tire pressure of at least 100psi, as long as you don’t ride for a day, it will drop by 5~10psi, the lower the tire pressure, the more likely it is to break the tire).
3. Oil the chain every time you ride for about 100 kilometers and wipe the excess oil clean
4. Wipe the whole car once a month. You can wipe it with a dry cloth. It is roughly clean. It does not need to be wiped to 100 points. On the contrary, it can shorten the working hours and it is more important to continue to do it.
5. Return to the car shop every six months to check the wear of the chain and tires.
Second, the complex version
1. Wheel system
a. Pump up regularly (once a week, or before each ride).
b. Check the tire pressure to keep the tire pressure at the proper pressure (once a week, or before each ride).
c. Check the tire wear and pick out the small thorns (once a month).
d. Check the degree of skew of the wheel frame (once a month).
e. Check the resistance of the hub and maintain the hub and ratchet (once a year).
2. Brake system
a. Whether the braking force is normal (once a week, or before each ride).
b. Check the wear and dirt of the brake pads (once a month).
c. Check whether the position of the brake pads is displaced (once a month).
d. The aging and rusting of the brake pipeline (once a year).
3. Transmission system
a. Chain cleaning (once a week, or after each ride).
b. The chain is oiled occasionally, and the excessive oil is wiped off (once a week, or once every 100 to 200 kilometers).
c. Measure the stretch value of the chain (1 time in 1000 kilometers, or once a month).
4. Frame body
a. Cleaning the front fork of the frame (once a week, or after each ride).
b. The frame, whether there are cracks, trauma, or corrosion (once a month).
c. Whether the front fork is cracked, injured or corroded. (Once a month).
d. Car head bowl bearing maintenance inspection (once a year).
