On the sides of the tyres you can see the recommended pressure for each tyre. On a standard cycle with normal width tyres a 4-bar pressure should suffice. On a racing cycle you may need up to 6-7 bar.
Those with an electrical cycle should check the tyre pressure monthly as too low tyre pressure will have a significantly adverse effect on the range. Do you want to cycle economically and get as long a range as possible? Ensure your electrical cycle's tyres are properly inflated.
