How to Change A Bike Tube?

Changing a bike tube?

Make it in 6 steps – Can you do it?

Step 1: Remove the wheel

If you have a puncture in the rear tire, move your gear to the back of the rear wheel to make it easier to remove the wheel.

You need to remove the brake before stripping down to the wheel from the bike, this is not a concern if your vehicle uses disc brakes.

Release the brake by pulling it out on the lever, after opening it using the other hand to remove it. Breaking the brakes will help the wheel to be removed.

To remove the front wheel, straighten it from the fork. With the rear wheel, pull the back strap to keep the chain free.

Step 2: Remove the valve cover and vale plug

After the tire is removed from the bicycle, remove the valve cover and valve plug, the collar. Press down on the valve to let all the air escape the inner tube of the tire.

Use your thumb to push the tire against the edge of the other side. Removing the tire from the rim requires the support of steel or iron levers.

Fix the tire lever at one tire rim. After pressing down the lever, push the lever to make the tire rim up.

The second lever underneath the tire rim, using the lever to slide the lever to the edge of the tire to remove it from the rim.

Step 3: Remove the tube

Please take the inside valve out of the valve hole and pull the tube out of the tire.

Using the four tips of the finger to gently slide along the tire to check for the cause of puncturing and detecting the relics in the tire.

In addition, you can also use a little wool because when you use the hand can be sharp objects like thorns, pieces of terry can hurt the finger.

Step 4: Change a bike tube

Need to remove the valve cover, open the valve of the new inner tube.

Use the pump to check if the tubes are properly shaped, are there faults that cause a slight detector?

Insert the valve into the inside of the valve hole, tighten the valve locking ring. Put the rest of the tube inside the tire.

Step 5: Reattach the tube

Starting from the valve position, start pushing the tire rim over the rim. Continue to push it.
This is easier with some tires/rim combinations than others.

If their combination is tight, the thrust of the rim meets some of the difficulties that require leverage.

Using the thumb or lever to push the last part through the rim (this requires strength).

Once they are together, check the two sides of the tire to ensure that the unclogged taps hold the grooves in the rims and tires so that they can explode when injected.

Step 6: Pumping tires

Connect the pump to the internal valve.

Push the pump head down to the pump. Inflate the inner tube with pressure on the wall of the tube. After inflating, ensure that the bolt is locked to the valve seat, the valve head is locked.

Step 7: Reassemble the wheel

To install the rear wheel, you need to get the chain clear by pulling back after the derailleur.

Place the smallest gears on the wheel at the bottom of the transmission line, guide the wheels back up and make sure the disc brakes are aligned if you use them.

For the front, guide the wheel up into the dropouts.

Use the other hand to tighten the screw, stopping when you can feel the resistance on the lever fast.

Finally, you did it!!!
