(1) How to protect the bicycle plating layer?
The plating on the bicycle is chrome plating, which not only increases the beauty of the bicycle, but also extends its service life, so care should be taken to protect it.
①Wipe it often. Generally speaking, it should be wiped once a week, using cotton yarn or soft cloth to wipe off the dust, and then adding some transformer oil or machine oil to wipe it.
② Riding a bike should not be too fast. Normally, the fast wheels will lift the gravel on the ground, forming a great impact on the rim and causing damage to the rim. Most of the serious rust holes in the rim are caused by this kind of reason.
③The bicycle plating layer should not be in contact with salt, hydrochloric acid and other substances, and should not be placed in a place where coal smoke is smoked.
④If there are rust stains on the plating layer, you can gently wipe them away with a little toothpaste. Do not wipe the galvanized layer of the bicycle, such as the width of the strip, because the dark gray layer of alkaline zinc carbonate generated on the surface can protect the internal metal from corrosion.
(2) How to extend the life of bicycle tires?
The road surface is mostly high in the middle and low on both sides, so when bicycles are driving, they must be on the right side. This is because the left side of the tire is often more worn than the right side. Also, because the center of gravity is backward, the rear wheel generally wears faster than the front wheel. If you swap the front and rear tires after using the new tires for a period of time, and swap the left and right directions, you can extend the life of the tires.
(3) How to maintain bicycle tires?
Bicycle tires have good wear resistance and bear a large load. However, improper use will often accelerate wear and tear, cracking and bursting. Usually, the following points should be noted when using a bicycle:
① Inflation should be appropriate. Insufficient inflation of the inner tube causes deflated tires, which not only increases resistance and cycling effort, but also increases the friction area between the tire and the ground, which accelerates the wear and tear of the outer tire. Inflation is too much, coupled with the sun and air expansion inside the tire, the tire cord is easy to be swollen off, will shorten the service life. Therefore, pumping should be
The right amount, cold weather can be enough, less in summer; front wheel gas less, rear wheel gas to be enough.
Do not overload. The side of all kinds of tires are marked with its maximum load weight. For example, the maximum load weight of the common tire is 100 kg, the maximum load weight of the weighted tire is 150 kg. Bicycle cutter and the weight of the car itself is divided by the front and rear tires but. The front wheel bears the total weight of l/3, the rear wheel is 2/3. rear hanger on the load almost all pressed on the rear tire, overload too heavy, increasing the tire and ground friction, especially because the tire side of the rubber thickness than the crown (pattern at) is much thinner, often heavy load easy thinning cracks, in the tire shoulder burst.
(4) Bicycle chain slippage treatment method:
The bicycle chain will slip after a long time. This is caused by the wear of one end of the chain hole, and the following method can be used to solve the problem of slipping teeth.
The chain hole is subject to friction in four directions, so if you open the joint and turn it over, the inner ring of the chain will become the outer ring, and the damaged side will not directly contact with the large and small gears, then it will not slip anymore.
