What are some easy bike repair methods you know? Detailed description

1. Pick the tire with bare hands.

2. The inner tube of the road car is only replaced and not repaired.

3. It will be easier to rotate to a small disc after unloading (the electric change party can't hang up) 4, any disc brake disc scoop is directly broken.

Carry some repair parts with you on the bike, and when the chain of the bike is dropped, you will turn the chain to put it back on.

When the chain of the bicycle breaks, I will replace the bicycle with a new chain and repair the handlebars of the bicycle.

I think the easiest way to repair the bike is to reinforce the bike with a lot of screws.

If the bike is loud, just drop a little lubricating oil and it won't be so loud.

The easiest way to fix your bike is to go to a repair shop to get it repaired, which is more convenient and quick.

I know that the easy way to fix a bicycle is to figure it out yourself and avoid the faults.

**Repair it if it's broken**, anyway, now the car repair is to disassemble and replace the accessories, it's a very simple thing. Inner and outer tubes, spoke rims, wheels, transmission kits, various changes.

I think it's the kind of thing you can buy yourself when the tires don't have air.

There are actually quite a lot of bicycle repair methods, anyway, you can learn a lot by repairing a mile of repair. It's just that.

Some of the simple ways I know to fix a bike are to use a wrench to get the chain off.

If the bike has noise, kick it twice.

In addition to the kit fork, most people will get the bike, and they won't go to the store to let the master show you, how big is it.

Won't be repaired! At most, the brakes are not working, remove the brakes and tighten them! And it's the brake line!

It means that the fork was changed and two sets of bowls were broken.

You should tighten the screws, tighten all the screws, and push slowly to see if there is a problem.

1 The adjustment method of the ordinary front brake is as follows: loosen the brake nut with a wrench, lift the front brake fork and the front pull tube up with the left hand, so that the distance from the brake skin to the rim is only 1 mm, and then use the right hand to pull the short pull rod on the handlebar down, make the short pull rod and the front pull pipe in a straight line, tighten the brake nut, and after letting go of the left hand, the brake skin will drop 1-2 mm, so that the brake skin is about 3 mm away from the rim. 2 4 The adjustment method of the ordinary rear brake is:

First loosen the clamping nut under the frame, then tighten the adjusting nut, adjust the brake skin to about 3 mm from the rim, tighten the clamp nut, if the brake is too close to the rim, adjust in the opposite direction. If the ram, short tie rod, rear pull pipe and other parts are loose, or the tension angle of the rear crank spring is too large, and the elasticity is small, you can tighten the loose brake screw, lift the rear pull tube up with the left hand, so that the brake skin is close to the rim, and then use the right hand to pull down the short pull rod of the handlebar, so that the short pull rod and the rear pull pipe form a straight line, and then tighten the brake screw, when the rear crutch spring is loose, and can not be adjusted up when the rear pull pipe, you can tighten the nut on the long pull rod joint, pull the back crank forward, make the rear brake skin, the rear brake fork move forward, and press the rear crank spring at the same time, Finally, tighten the nut on the long tie rod joint.

When braking, the contact area between the brake pad and the rim on one side is large, and the contact area between the brake pad and the rim on the other side is small. The reasons for this failure are: (1) The front wheel or rear wheel is not aligned, the front wheel or rear wheel should be aligned, so that the distance between the front rim and the left and right fork legs is equal, so that the rear rim.

The distance between the left and right flat fork legs is equal; (2) If there is axial flutter in the rim, the axial flutter of the rim should be eliminated; (3) When the ram is misaligned, the screws on the splint should be loosened, the ram should be straightened, and the screws should be tightened; (4) If the fork is deformed, you can use a wire cutter to clamp the brake and turn to correct the deformed fork. If the brake skin is facing outward, the brake fork can be pulled inward; On the contrary, pull outward, and then adjust the position of the ram to make the left and right brake skin symmetrical. 4 43 When braking, the brake pad touches the rim one after the other and causes this failure and the way to overcome it is:

1) If the fork is not corrected, when the front fork is installed, the screws of the brake screws and the screws of the ram should be tightened, and the ram and the front fork should be straightened, and then the screws should be tightened. When the rear brake fork is straightened, the splint screw should be loosened, the brake fork should be straightened, if it is still not possible, the nut on the rear crank plate should be loosened, the rear crank plate should be rotated, and the rear crank should be straightened; (2) If the brake fork is deformed, the brake fork should be corrected, if the brake skin on the right side of the brake fork first touches the rim, the straight part of the brake skin can be pulled down to make the brake skin leave the rim, or the left straight part is pulled upwards to make the brake skin close to the rim; Conversely, the pull is in the opposite direction.

Very good repair, the chain is wiped with oil, the car is often wiped with a rag, and the screws are often checked and tightened

You can fix it yourself, and you can buy a car repair tool online.
