100 points How to change the inner tube rear wheel of a normal bicycle by itself?

Follow the steps below.

1. Prepare tools, such as wrenches, spudgers, etc.

2. First remove the tires from the car, and you must replace the tires completely.

3. Then use a spudger to pry the tire open, this part will be more difficult.

4. Once the tire starts to fall off, the inner tube is easy to take out of the inside of the tire.

5. Give a little air to the new inner tube first, it will be easier to install.

6. Stuff the inner tube into the tire, and then restore the buckle of the outer tire to ensure that it is fastened and fully inflated.

7. Put the wheels back on the frame and you're done.

1. Remove the chain from the rear wheel flywheel and loosen the screws of the rear wheel upper chain adjuster 3-5 teeth.

2. Loosen the nuts on both sides of the rear wheel, remove them, and remove the parking rack.

3. Loosen the brake line locking screw on the brake brake to make the brake line completely detached from the brake on the rear wheel.

4. Loosen the brake fixing screws to facilitate the removal of the rear wheel from the frame.

5. Loosen the valve cap screw on the rear wheel and completely release the inner tube.

6. Find a movable wrench and a flathead screwdriver, first pry the screwdriver into the outer tire and the edge of the rim, pick out the outer tire, and then use the movable wrench to extend the position to completely separate the outer tire from the steel ring and take out the inner tube (if there is a special tire cutting tool, it is best to use a special tool to prevent the outer tire from being punctured).

7. After pre-inflating the inner tube, fix the air valve on the valve hole of the steel ring, and put the inner tube into the outer tire (pay attention to check whether there are sharp objects such as iron filings in the outer tire before padding the tire).

8. Clamp the wire edge of the outer tire edge into the steel ring, which needs to be completely snapped, otherwise it is easy to burst when the rear is inflated (during the operation, it is necessary to pay attention to the lining belt on the outer edge of the steel ring should not be skewed to prevent the copper head on the wheel from puncturing the inner tube).

9. Inflate after the tire is completed.

10. Put the rear wheel into the wishbone of the frame and attach the chain to the rear flywheel.

11. Install the fixing screws of the brake and lock the screws of the chain adjuster.

12. Lock the rear wheel screw.

13. Lock the brake line tightly.

Follow the steps below.

1. Prepare sock letter tools, such as wrenches, crowbars, etc.

2. First remove the tires from the car, and you must replace the tires completely.

3. Then use the balance wheel crowbar to pry the tire open, this part will be more difficult.

4. Once the tire starts to fall off, the inner tube is easy to take out of the inside of the tire.

5. Give a little air to the new inner tube first, it will be easier to install.

6. Put the inner tube plug into the tire, and then restore the buckle of the outer tire to ensure that it is fastened and fully inflated.

7. Put the wheels back on the frame and you're done.

To replace the inner tube of the rear wheel of the bicycle, first unscrew the nut that holds the axle and remove the wheel; The specific steps are as follows:

1. Unscrew the nut that fixes the axle first.

2. Take the wheels off.

3. Press the valve firmly to deflate.

4. Use a crowbar to reach into the gap between the outer tire and the rim.

5. Insert another crowbar into the gap between the outer tire and the rim and pry downward.

6. Take the inner tube out of the outer tire.

7. Install the new inner tube back, install the valve first, and the operation is completed.

To change the rear inner tube, you need to remove the rear axle, first need a torx wrench, remove the rear wheel center axle screw, and then take off the rear wheel (together with the flywheel, don't disassemble the flywheel, otherwise it will not be easy to install).

Then find something to pry off the tire along the edge of the tire, using a tire lever, steel plate, and screwdriver. But don't puncture the tires too hard.

Pry off the outer tire, pull the inner tube out, and replace it with a new inner tube corresponding to the valve hole on the rim.

Put the outer tires back in the opposite direction just now, then put on the wheels, install the chain, and just cheer up.

Flat tire is also one of the most common situations encountered by many riders, what to do if you are riding a bicycle and have a flat tire? The most common thing that many people encounter is a broken inner tube that needs to be replaced with a new one, so if you love cycling, you must not miss these tips.

First of all, make sure you have these items with you before you hit the road: a mini pump, inner and outer tubes, 2 tire digging sticks, and gas cylinders.

1.Whether the front or rear tires have a puncture, they must be removed for disposal, and it is important to remember that the first step is to put the caliper up and loosest it.

The front wheels are relatively easy to remove, just release and quick release; The rear wheel needs to be practiced, first match the tooth ratio of ** and the rear flywheel to a small to small position, so that the chain is put to the loosest, and then grab the frame with one hand; Holding the wheels with one hand and applying force to the frame up and the wheels down, the frame and rear wheels can be separated.

2.Then start to deal with the broken wheel belt, first use the first tire digging rod, plug it into a place slightly away from the air valve in the way of hooking, and then place the second tire digging rod at a distance of about 10 to 15 cm from the first tire digging rod, and start digging from the inside to the outside from the second tire digging rod, and one of the outer tires will be out of the rim.

3.When the other side of the outer tire is still on the rim, slowly pull the inner tube out, and finally pull out the air valve. Before attaching a new inner tube, make sure that there are no sharp objects left on the inside of the wheel belt.

Installing the inner tube is different from pulling out the inner tube, starting from the valve part during installation, and the rest of the process of inserting the inner tube should be kept flat and not twisted.

4.Finally, the outer tire is attached, and the power of the two fingertips is properly used to press the wheel belt from both sides to the outside in a spreading manner, because if you follow the same direction, the other side will run out.

Because of the different characteristics of the wheels, if the tire is hard, pressed to the last small section, it is better to use the tire digging rod, but it is recommended to use the strength of the fingertips as much as possible, so as not to hurt the new inner tube by digging the tire rod, and you can use a gas cylinder or a portable pump to pump after installation.

But I can change the inner tube after the bike, take a look at these steps below.

1. There is an inner tube system: all ordinary bicycles and most sports bicycles are in use, and the advantages are low cost, wide popularity, and convenient purchase and replacement. The disadvantage is poor athletic performance.

2. Tubeless system (also known as vacuum tire): high-end mountain bikes and road bikes are gradually popular, with the advantages of good road feeling, strong integrity and good sports performance, and the disadvantage is that the use cost is high and the requirements for installation and replacement are high.

3. Tube tires (simply put, a ring tire is attached to the wheel, as if there is no outer tire): the top competition-level road bikes and some top mountain bikes generally use this kind of tire, the advantage is that the sports performance is the best at present, and the disadvantage is that it is very expensive, the installation is the most troublesome, the repair is the worst, and the life is short.

Speaking of cars, not all cars use tubeless, and trucks have inner tubes.

As for why the proportion of cars using tubelesss is high, this is also gradually discovered, initially cars also have inner tubes, and now bicycles are also discovering, and the proportion of tubelesss will gradually increase.

To replace the inner tube of the rear wheel of the bicycle, first unscrew the nut that holds the axle and remove the wheel; The specific steps are as follows:

1. Unscrew the nut that fixes the axle first.

2. Take the wheels off.

3. Press the valve firmly to deflate.

4. Use a crowbar to reach into the gap between the outer tire and the rim.

5. Insert another crowbar into the gap between the outer tire and the rim and pry downward.

6. Take the inner tube out of the outer tire.

7. Install the new inner tube back, install the valve first, and the operation is completed.

Before you start, look at your trachea and see if the tire removal tools are complete, and then do it.

Dismantling: If the rear tire is quick to disassemble, just pull open the left quick release handle, at 90 degrees with the axle, and then loosen the right bolt counterclockwise by hand, reverse the car to the left, and remove the axle groove while the wheel is moving. Pinch the tire hard, insert it into the rim with the skid, pick it up and slide to the side, and the outer tire will come out of the tire groove and pull out the inner tube.

Loading: Insert the inner tube valve into the hole first, and then stuff it into a circle of whole tires. Pinch the outer tire hard, so that the outer tire edge enters the tire groove, and then delay the completion of a circle, and when it is about to close, pinch the outer tire with one hand to position, and pinch the tire edge with the other hand to move forward, and the whole circle is OK

Inflation: Pinch the outer tire at the air valve firmly, make the air valve plug into the trachea mouth, pull up the trachea handle to lock it, and start to add gas.

Loaded into the axle groove: pay attention to the chain should be wrapped outside the gear, that is, there should be a chain up and down the gear, so that the axle enters the axle groove, lift the car, make the car perpendicular to the ground, tighten the right side of the bolt, so that the left handle plate needs to be forced when it is poured. Look at the chain so that it is on one gear. Complete.

It's very simple, deflating the tires and it's done.

How to change the inner tube of your bicycle.

Prepare the tools Some tools are required to change the inner tube of your bike. First, you'll need a good pair of tire calipers to use to disassemble and assemble your tires. Secondly, you need a good pair of glue and some patches to repair the tire. Finally, you'll need some new inner tubes.

Preparation First, you need to straighten up the frame of your bike so that you can change the tires. Next, use a clamp to separate the wheels from the frame, removing the outer tire and then removing the inner tube. Then check whether there are nails, glass ballast, etc. on the outside of the tire by inspecting the tire.

In this step, if Bi Suiguo finds that the tire has punctures and other damage, it needs to be repaired with patches and glue first.

Changing the inner tube After getting the new inner tube ready, first confirm that the new inner tube is the same size as the previous inner tube. Next, place the inner tube into the outer tire. Put the outer tire on the inner tube from the side of the inclined plane, and then slowly press the outer tire upwards to the inside to make sure that the entire outer tire is full of inner tubes.

Finally, the wheels were re-attached to the frame using the clamps, and the tires were successfully replaced.

Precautions The following points need to be paid attention to when changing the inner tube of the bicycle. First of all, the inner tube must match the size of the outer tire. Secondly, in the process of putting the outer tire, the outer tire must completely wrap the inner tube to avoid problems such as air leakage, puncture and friction during driving.

Finally, after replacing the inner tube, you should check whether the tire pressure is sufficient before riding, and it is best to check if there are any other problems. Raid the wilderness.

Conclusion Changing a bicycle inner tube is not a difficult task and can be done easily with the right tools and techniques. It should also be noted that regularly checking the condition of bicycle tires can better ensure the normal use of the bicycle.

Bicycles are one of the commonly used tools for our daily travel, but in the process of use, it is inevitable to encounter problems such as broken inner tubes of the rear wheels or aging of outer tires. At this time, we need to carry out the operation of changing the inner tube of the rear wheel to the outer tire.

First, you need to place the bike upside down on the ground and lift the rear wheel off the ground. Then use a tool to gently pluck the edge of the outer tire, find the air valve of the inner tube, remove the gasket next to the air valve, pull out the air valve, and then remove the inner tube from the outer tire.

Next, place the new inner tube in the outer tire with the dust pants high and insert the valve into the valve hole, then place the gasket next to the valve. Place the rest of the inner tube into the outer tire, taking care not to crumple or squeeze the inner tube out. Then, gradually push the edge of the tire back onto the rim until the entire tire is fully embedded.

In the last step, the valve washer is swirled back into its original position, the valve is inserted into the cylinder, and then the cylinder is attached to the valve to inject air into the inner tube until the proper air pressure is reached. Be careful not to inflate too much to avoid a ruptured inner tube.

Changing the inner and outer tires is a basic bicycle maintenance operation, and with this skill, we can solve the problem by ourselves when we need to, and avoid delays due to breakdowns. At the same time, it is also necessary to pay attention to safety when changing tires to avoid accidents caused by negligence.
