Why does the front wheel of the bicycle ring, there is a sound when the rear wheel of the bicycle tu

First of all, you should listen carefully to what part of the front wheel is ringing

Summary. 1. The ratchet and ratchet in the flywheel produce a clicking sound during gliding. (normal sound) 2. The clicking sound caused by damage to the bearing or ball in the hub. At the same time, it will be accompanied by poor rotation of the rear wheel (bearing or ball needs to be replaced).

3. There are gravel embedded in the outer tire, and when driving on the asphalt road or hard road, the sound of the stone hitting the ground. (normal sound).

There is a sound of the rear wheel of the bicycle turning.

1. The ratchet and ratchet in the flywheel produce a clicking sound in the gliding Kai Huanmu. (normal sound) 2. The clicking sound caused by damage to the bearing or ball in the hub. At the same time, it will be accompanied by the rear wheel rotation without hail (the bearing or ball needs to be replaced).

3. There are gravel embedded in the outer tire, and when driving on the oil road or hard road, the sound of the stone hitting the ground is clicking. (normal sound).

Give a thumbs up thanks.

In this case, you can just fix it, and it's not a big problem.

There are several cases:

1. The gear is worn, and the chain jumps;

2. Improper gear change, such as the front crankset is the largest and the back is also the largest, and the chain must be hung;

3. The gear is deformed, and the chain will be rubbed when it turns to a specific position;

4. The gear positioning is inaccurate, the gear is unstable, and the force will fall off or grind the chain as soon as the force is deviated.

Suggestion: Go to the original point of sale to find a professional to adjust, or go to a local specialty store to have it repaired by a professional technician.

Regular maintenance

1. After riding the bike for a period of time, each component should be checked and adjusted to prevent the parts from loosening and falling off, and the sliding part should be regularly injected with an appropriate amount of oil to keep it lubricated.

2. Once the vehicle is wet or damp, the electroplating parts should be wiped dry and wiped clean in time, and then coated with a layer of neutral oil (such as household sewing machine oil) to prevent rust.

3. The parts coated with varnish should not be rubbed with oil, so as not to damage the paint film and make it lose its luster.

4. The inner and outer tires of bicycles and brake rubber are rubber products, and contact with engine oil, kerosene and other oil products should be avoided to prevent rubber aging and deterioration. New tires should be fully inflated. Usually, the tire should be properly inflated, and if the air is insufficient, the outer tire is easy to break; If you pump too much, it is easy to injure tires and parts.

The correct approach is: the front tire should be inflated less, and the rear tire should be inflated more. You should be full of gas in cold weather, and not too much in hot weather.

5. The bicycle carries an important appropriate amount. Ordinary bicycles, with a load capacity of no more than 120 kg; Load bikes, the load capacity must not exceed 170 kg, since the front wheels are designed to carry only 40% of the weight of the whole car, so do not hang heavy objects on the forks.

% of the ringing** on the brake pads.

If the brake pad is not worn out and the scraper is issued, as long as the brake pad is replaced, or it is caused by the aging of the surface of the brake pad or the sharp corners, only the surface and corners of the brake pad can be solved;

The sound of the brake disc**.

Issue. Either the brake disc is deformed, and the left and right swing is lifted to the brake pad when driving, and the brake disc can be repaired by grinding the loss of roundness, or the brake disc surface is rusty, and the sound made when the brake pad scrapes off the rust spots on the surface of the brake disc will automatically lose the sound of driving for only a few minutes, because the rust spots are worn off when braking.

It is the problem caused by other individual factors.

For example, the brake plate is loose, not installed after disassembly, and there are parts damaged after impact.

4. The brake pad and the brake disc do not match.

For example, if you just change the brake pad or brake disc, it and the brake pad is a friction pair, it will definitely have some protruding places, it is uneven in the first few tens of kilometers of initial wear, so there will be all kinds of noise when you step on the brake, this noise is normal, don't pay attention to it. This requires the car to brake without deviation, nothing important for everyone to drive normally.

5. There is a foreign object between the brake disc and the brake pad.

Sometimes walking in a dirty place, the brake disc and the brake leather are sandwiched into the sand, and it makes a sound when it is stepped on between the brake disc and the brake, which does not affect safety. If you press the brake a few times, it will disappear, and it doesn't matter. There is also a possibility that after the water is said, there is water in the friction pair of the brake pad and the brake disc, and it will make a whining sound, and the brake should disappear after stepping on the brake, which does not matter.

The brakes are worn to the limit.

6. Finally, because the brake pad is a consumable.

It has thickness. When the manufacturer deliberately adds some metal particles when it is closest to the wear limit, it will produce a different noise than usual when you step on the brakes, to remind you that the brake pads should be replaced. Because the braking system is related to driving safety, this can not be delayed or ignored.

For the problem of bearings, it is recommended to replace the bearings, otherwise the wear will be more serious, and it is not expensive, and it will be expensive to replace the bearings after they fall apart.

Does this affect driving? Bearing problems, it is recommended to replace the bearing, otherwise the wear is more serious, and it is not expensive. It is more expensive to replace the bearings after they are scattered.

Affect riding? Bearing problems, it is recommended to replace the bearing, otherwise the wear is greater and not expensive, such as the bearing is damaged and then replaced will be very expensive.

Does it affect riding? For leasing problems before Chunji, it is recommended to replace the bearings, otherwise the wear will be more serious and not expensive. When the bearing is spread out, it will be very expensive to replace the shaft and clear the bearing.

There are generally three reasons for the sound of the rear wheel: first, the steel ball or ball box (also called the file) in the shaft is damaged; Second, the spokes are loose, and the rim makes a sound when riding; The third is that the rim jumps horizontally, and the tire or rim touches the frame.

The lateral runout of the rim can be corrected by adjusting the spokes, and if it is not for the rim to be severely deformed or cracked, it is not necessary to change it.

Mountain bikesThe disc brake has a ringing sound, probably because the disc brake or the liquid is causing water or oil on the plateWater or oil on the disc brake or liner will reduce the friction between the disc brake and the lining.

As a result, the braking effect is reduced, and it is necessary to clean the disc brake and liner blades.

If there is a sound of disc brakes on mountain bikes, it may be that the wear of the ring or disc brake is too serious, and then it is necessary to replace a new disc brake or a ring plate.

Mountain Bike Frame Requirements:

Because the mountain contains the ro-ro car on its own.

It is more laborious to drive, so the frame of a mountain bike should be correspondingly smaller than that of a regular bike. This construction is built with the bike off-road in mind.

The characteristics of the movement, on different grounds, the bicycle is more convenient to operate.

The material, construction, and design of the frame are important to creating an efficient, safe, and reliable bicycle that needs to withstand shocks caused by a variety of reasons.

Summary. <>

Hello dear, glad your question Why does the bike ring? 1. The transmission system (crankset, chain, flywheel) lacks cleaning and maintenance or lacks lubricating oil, and the deposition of dirt, rust and dryness will make all parts of the transmission system have abnormal friction, so many metal parts rub around in the harsh environment. Therefore, it is necessary to maintain the transmission system of the bicycle frequently, use a special cleaning agent to thoroughly clean the transmission system, re-oil, and replace the parts with serious rust in time.

2. Transmission system fatigue: After the bicycle travels a long distance, the transmission system often has different degrees of wear or fatigue, such as the chain is elongated, the tips of the flywheel and crankset are worn, and even the teeth are broken. These conditions can lead to a significant reduction in the biting capacity of the drivetrain, resulting in noise and even undesirable phenomena such as tooth jumping.

Therefore, every 5,000 kilometers, the new chain should be replaced, and when about 10,000 kilometers, the flywheel should be considered to be replaced to ensure that the transmission system can work normally and efficiently. 3. The bearings of the central shaft and pedal are seriously watered or worn, which can also lead to abnormal noise. Sometimes, after riding in heavy rain, your bike may have a "crunch" sound when pedaling, which may be the bottom bracket or pedal bearing water ingress, this abnormal sound is more common in the low-end parts, most of which will be eliminated after the water evaporates.
