How to pump a bike tire

How to inflate a bicycle tire is very simple, but beginners often have trial and error, so I'm going to write about how to inflate a tire.

 

 

 

1. First, remove the rubber stopper by turning it.

 

 

 

 

The air inlet of the bicycle wheel is usually covered with a black stopper as shown in the picture.

 

 

 

 

 

2. Unscrew the device that blocks the inflow of air.

 

 

 

 

 

If you remove the black rubber, it will be like the picture. Unscrew the marked device by hand. You don't have to completely uninstall it.

 

 

 

 

 

3. As shown in the picture, you can inject air after loosening the device that blocks air inflow to some extent.

 

 

 

 

 

Don't remove it completely, just loosen it to some extent.

 

 

 

 

 

4. If you press the air injection machine against the inlet and push it all the way in, air will come in.

 

 

 

 

 

Each machine is a little different, but in most cases, air can be injected by pressing against the inlet.

 

 

 

 

If you ride a bicycle with insufficient air pressure, you may fall over and your tires may be easily damaged. Check the air pressure in the tires, and if the air pressure is low, put air in the tires and ride. :)
