Merida mountain bike, how to maintain it? Riding attention? Technology? Knowledge?

Usually I send it to the car shop for maintenance.

Formal purchase of products, no replacement of accessories, maintenance is generally free of charge.

The so-called maintenance is generally used by the store to fool consumers.

As far as bicycles are concerned, the cycle of not maintaining different parts is not necessarily the same, and due to different use conditions, some parts need to be maintained while others do not need maintenance. Maintenance is mainly where there are bearings or loose beads, such as the bottom bracket, hub, pedal, etc., the brake also needs to be maintained under certain circumstances, and the transmission system should be maintained on a daily basis.

If the so-called whole car maintenance, all the parts are disassembled for cleaning, oiling, adjustment, it seems to be a good thing, in fact, if your hub does not need maintenance and disassemble maintenance, it will affect the service life, coupled with the level of the technician, it is possible that the maintenance will only be faster if the maintenance is not good, the most typical is the maintenance of the loose bead hub, no maintenance, bad maintenance is better than no maintenance.

The maintenance of this thing completely depends on the character of the boss around the place, and the simple maintenance of good people is not charged, but there are very few good people, and it is more than 20 yuan to clean the chain, crankset, flywheel, etc.

The chain of the mountain bike should be maintained according to the use of the condition, such as full lubrication before off-roading, timely cleaning of sediment after off-road, oiling lubrication and rust-proofing, and the chain with mud and sand has great damage to the chain and flywheel. (Generally, it is best to maintain it once before and after each off-road).

According to the use of the variable speed line pipe, about half a year to a year or so to add graphite lubricant

The brake is a guarantee of safety, and it is best to check whether the cable (V or line disc) or oil pipe (oil disc) is defective before each off-road, whether the stroke needs to be adjusted, and whether the rebound is in place

The fork usually pays attention to dustproof, and it is best to disassemble and maintain it once a year or so, and the off-road time is slightly shortened, and it is generally okay to leave it alone

Generally, cranksets and flywheels do not require special lubrication, lubrication chains are sufficient

Hubs, generally no problem just leave it alone

It is best to check the rim from time to time for deflection, broken wires, etc

Tire repair is a technical job, it is troublesome to learn to repent, it is more convenient to hand it over to the car repair master, and it can be done for one or two yuan

Last but not least, the tightening of the screws is very important, it is very dangerous to loosen during riding

Look what kind of annihilation car you are. If it is a general Daishi good knowledge scooter, there is basically no maintenance. It's okay to guarantee normal operation.

If it is a mountain or road race socks destroyed, or a BMX (these cars are usually more than 2000 yuan), usually the main maintenance of the transmission part, such as cleaning the chain every once in a while, oiling or something, it is best to remove the chain, and then clean the crankset and flywheel together, and there is a special bicycle chain oil if oiled. If it is a mountainous area, pay attention to cleaning the dust on the inner tube. That's all for the initial maintenance.

Tire repair is the same as the street master, now there are a lot of tire repair tools on the Internet, things are basically complete, there are many tutorials, buy a set of your own learning.
