(1) How to protect the electroplating layer of folding bicycles?

The electroplating layer on the folding bicycle is generally chrome plating, which not only increases the beauty of the folding bicycle, but also prolongs the service life, and should be protected at ordinary times.

Wipe frequently. Generally speaking, it should be wiped once a week. Use cotton yarn or soft cloth to wipe off the dust, and add some transformer oil or oil to wipe. If you encounter rain and blisters, you should wash it with water in time, dry it, and add more Oil.

Cycling should not be too fast. Usually, the fast wheels will lift up the gravel on the ground, which will cause a great impact on the rim and damage the rim. Serious rust holes on the rim are mostly caused by this reason.

The electroplating layer of the folding bicycle should not be in contact with substances such as salt and hydrochloric acid, and it should not be placed in a place where it is smoked and roasted. If there is rust on the electroplating layer, you can gently wipe it off with a little toothpaste. Do not wipe the galvanized layer of folding bicycles such as spokes, because a layer of dark gray basic zinc carbonate formed on the surface can protect the internal metal from corrosion.

(2) How to prolong the life of folding bicycle tires?

The road surface is mostly high in the middle and low on both sides. When driving a folded bicycle, you must stay on the right side. Because the left side of the tire is often more worn than the right side. At the same time, due to the rearward center of gravity, the rear wheels generally wear out faster than the front wheels. If the new tires are used for a period of time, the front and rear tires are replaced, and the left and right directions are reversed, which can prolong the life of the tires.

(3) How to maintain folding bicycle tires?

Folding bicycle tires have good wear resistance and can withstand large loads. However, improper use will often accelerate wear and tear, cracking, blasting and other phenomena. Usually, when using a folding bicycle, you should pay attention to the following points:

Inflate to the right amount. The deflated tire caused by insufficient inflation of the inner tube not only increases the resistance and makes cycling laborious, but also increases the friction area between the tire and the ground, causing the tire to accelerate wear and tear. Excessive inflation, coupled with the expansion of the air in the tire in the sun, will easily break the tire cord, which will shorten the service life. Therefore, the amount of air should be moderate, enough in cold weather and less in summer; less air in the front wheel and more air in the rear wheel.

Don’t overload. The side of each tire is marked with its maximum carrying capacity. For example, the maximum load capacity of ordinary tires is 100 kg, and the maximum load capacity of weighted tires is 150 kg. The weight of the folding bicycle and the weight of the car itself is divided by the front and rear tires. The front wheel bears 1/3 of the total weight and the rear wheel is 2/3. The load on the rear hanger is almost all pressed on the rear tire, and the overload is too heavy, which increases the friction between the tire and the ground, especially since the rubber thickness of the sidewall is much thinner than that of the tire crown (pattern), it is easy to become thinner under heavy load. A rip appeared and burst at the shoul

(4) Sliding treatment method of folding bicycle chain:

If the bicycle chain is used for a long time, the sliding teeth will appear. [Mountain Bike Special Issue] The daily maintenance and maintenance of the bicycle freewheel is caused by the wear of one end of the chain hole. If the following methods are used, the problem of sliding teeth can be solved.

Since the chain hole is subject to friction in four directions, as long as the joint is opened, the inner ring of the chain is turned into an outer ring, and the damaged side is not in direct contact with the large and small gears, so it will no longer slip.
