There are several ways to inflate a bicycle tire without a pump:
1. Use a CO2 cylinder
Preparation: Buy a CO2 cylinder and the corresponding nozzle.
Operation: Remove the dust cover of the tire valve. Connect the CO2 cylinder to the valve, quickly release the CO2, and inflate to the required pressure.
Advantages: Quick and convenient, suitable for emergency use.
2. Use manual method
Preparation: Find a plastic bottle or other container.
Operation: Make a small hole in the bottom of the bottle, making sure the hole is large enough for air to flow out. Aim the bottle mouth at the tire valve, and quickly press the bottle body to let the air enter the tire through the hole.
Note: This method may not be effective enough and is suitable for temporary emergency.
3. Use other tools
Method: If there are other tools that can generate air pressure (such as a hair dryer, compressed air tank, etc.), you can try to connect it to the valve.
Note: Make sure the pressure of the tool is suitable for the tire and do not over-inflate.
4. Find a temporary alternative
Method: Ask people around if they have a pump to borrow, or go to a nearby bicycle shop or gas station.
Advantages: This is the safest and most effective way.
Summary
Although there are limited ways to inflate without a pump, you can use a carbon dioxide cylinder or other tools for temporary inflation. It is best to carry a small pump with you in case of emergency.(Handheld Air Compressor Pump Tire Inflator For Car And Bicycle)
