Check tyre pressure
There are essentially three different types of bicycle valves:

Schrader valve (car valve) (1)

Presta valve (Sclaverand valve, French valve) (2)

Dunlop valve (3)
You can find information on the permissible tyre pressure on the
side of the tire. There will be a pressure range. Test which tyre
pressure is available for you.
We recommend a bicycle stand pump with a pressure gauge for
checking and correcting the tyre pressure.
Note for the Presta valve:

Loosen the union nut by one or two turns.

Briefly press the end of the valve in the direction of the rim.
If there is pressure in the tyre, air escapes audibly.

Screw the union nut back on tightly after the pumping process.
