Classic City Bicycle Exporters introduces the maintenance methods of bicycles:

1. Tire maintenance knowledge
The road surface is generally high in the middle and low on both sides, and bicycles must drive on the right. Therefore, the left side of the tire often wears more severely than the right side. At the same time, the rear wheels generally wear out faster than the front wheels due to the back of the center of gravity. Therefore, after the new tires are used for a certain period of time, the front and rear tires should be exchanged, and the left and right directions should be exchanged. In this way, its service life can be extended.

2. Tips for repairing the inner tube of the car
Bicycles are a good tool for pedestrians to travel, go to work, and travel. But in the process of riding a bicycle, the inner tube of the bicycle is often pierced with a sharp object, which brings inconvenience to travel. Let me tell you two tips for repairing the punctured inner tube. One is to paste several layers of medical tape (one layer is larger than the area of ​​the layer) on the small hole to be pierced, which can keep the inner tube from leaking for a long time. The medical tape is also very convenient to carry. Another trick is to go to the store to buy some leak trap. Before the parade, when repairing the bicycle, pour the inner tube of the bicycle. Once it is tied, the leak trap can fill the hole. You can travel with confidence.

3. Treatment of slow tires
Pull down the valve core, let out the air in the inner tube, take half a tablespoon of talcum powder, and slowly fill it into the inner tube with a cardboard cone. The problem of slow air leakage can be solved.

4. Avoid using sewing machine oil for bicycles
Sewing machine oil is a thin lubricating oil. If used in bicycles, the original butter in the car will be diluted and lost, thereby reducing the lubricating performance and rust resistance of the grease. Therefore, add oil to the axle of the bicycle and apply No. 30 oil or grease.

5. Tips for wiping your bicycle
If the bicycle is dirty and dusty, it can be wiped with a clean flannel or worn out cotton sweater. Then you take a few castor bean seeds, peel off the shell, wrap them in a flannel, etc., and smash them. Use it to wipe the bicycle to make the paint as bright as new. After wiping the bicycle rims and spokes, you can make it smooth and shiny, and Castor oil has an anti-rust effect. It won't rust even if it rains a little bit.

6. Tips for removing rust from bicycle chains
If the bicycle chain is rusty, first wipe off the rust spots with kitchen detergent, then clean the detergent on the chain and wash it in diesel oil to restore the bicycle chain to its original state.

7. Tips for bicycle calibration
For newly purchased bicycles, a comprehensive correction should be made to tighten the loose screws, pins, axles, handlebars, and front forks. The spokes on the wheels should be tightened according to the rim conditions. Before tightening the front, rear, and bottom axles, a gap between the axles of about 0.5 to 1 mm should be maintained to ensure brisk riding.

8. Tips for bicycle maintenance
For new bicycles, a pair of plastic grips should be used to protect the brake handles and increase the friction between the brake handles and hands. It is safer for cyclists, especially in summer. The installation method is: use hot water to cover the brakes. Thermally expand the sleeve, or sprinkle some talcum powder in the sleeve, so that it is easy to put on. If the saddle is equipped with a cloth, velvet or artificial leather seat cover, it will not only protect the saddle, but also be soft and comfortable and save pants. The pedal can be covered with a rubber pedal cover. Do not wrap plastic tape or wax cloth on the frame, front fork, etc., otherwise the paint will fall off easily. However, cloth strips should be placed between the car bell, handlebars, car lock splints and frame vertical forks, brake splints and front fork legs to prevent the plating and paint from being worn off.

9. Tips in the use of bicycles
Pay attention to the following aspects when riding a bicycle. Your bicycle will definitely be used for a long time, which is convenient for your life and travel. When encountering uneven roads and pits, ride slowly at a low speed to prevent the screws from loosening and sliding buckles due to severe cracks and vibrations. You should not ride at high speed or in a curve, and be careful not to brake too quickly, especially to prevent iron chips, glass and other objects on the ground from piercing the inner and outer tires. It is strictly forbidden to drive with overloading. The weight of ordinary vehicles cannot exceed 120 kg; the weight of heavy-duty bicycles cannot exceed 170 kg. Pay special attention to avoiding one-sided load to prevent body deformation. Don't even ride a bike to lead people, or violate traffic rules.
