It's a narrow type of tube valve. It's almost always used on road bikes, but some MTBs use it as well.
Yes, Presta valves require a pump with a smaller nozzle or an adapter for inflation.
Prestas and Schrader needs different nozzles. Schrader needs a bigger nozzle with a pin to open the valve in the middle.
To properly fill a bicycle tire with a Presta valve, follow these steps: Unscrew the top cap of the Presta valve and press down on the valve to release any remaining air. Attach the pump nozzle to the valve by unscrewing the tip of the nozzle and pressing it onto the valve. Pump air into the tire until it reaches the desired pressure. Remove the pump nozzle by unscrewing it from the valve. Screw the top cap back onto the Presta valve to secure it.
To pump a bike tire with a Presta valve, follow these steps: Unscrew the top cap of the Presta valve and press down on the valve to release any air inside. Attach the pump nozzle securely to the valve. Pump air into the tire until it reaches the desired pressure. Remove the pump nozzle and screw the top cap back onto the Presta valve.
To properly use a bike pump with a Presta valve, first unscrew the valve cap and loosen the nut at the top of the valve. Attach the pump nozzle securely to the valve, then pump air into the tire until it reaches the desired pressure. Finally, remove the pump nozzle and tighten the nut on the Presta valve to secure it.
To inflate bike tires with a Presta valve, follow these steps: Unscrew the top cap of the Presta valve. Press down on the valve to release any remaining air. Attach the pump nozzle securely to the valve. Inflate the tire to the recommended pressure. Remove the pump nozzle and screw the top cap back on.
To properly fill a bike tire with a Presta valve, follow these steps: Unscrew the top cap of the Presta valve and press down on the valve to release any air inside. Attach the pump nozzle securely to the valve by unscrewing the tip of the nozzle and pressing it onto the valve. Pump air into the tire until it reaches the desired pressure, which is usually indicated on the tire sidewall. Remove the pump nozzle carefully and screw the top cap back onto the Presta valve to secure it.
To air up a bike tire with a Presta valve, follow these steps: Unscrew the top cap of the Presta valve and press down on the valve to release any remaining air. Attach the pump nozzle securely to the valve by unscrewing the tip of the nozzle and pressing it onto the valve. Pump air into the tire until it reaches the desired pressure. Remove the pump nozzle by unscrewing it from the valve and replace the top cap.

Pump air into the tire until it reaches the recommended pressure level, which is usually indicated on the tire sidewall. Remove the pump nozzle and screw the top cap back onto the Presta valve. Check the tire pressure with a pressure gauge to ensure it is at the correct level.
