I recently got a new beginners road bike:
And an air pump:
But I have no idea how to use the bike pump. I really don't have that much experience with bikes, which is probably a large portion of the problem. Here are some questions I have:
How do you even use the pump? I imagined it would be intuitive but it isn't, at all. It looks like my wheels have a schrader valve (it's definitely not presta, could it be something else?), and my pump says it can work for these valves, but I can't attach the end of the pump on the part of the tire that takes in air at all. After reading the Amazon reviews I understand you have to do an operation to change the head in order to deal with schraders, but even after that, it still doesn't work for me.
When I was young, I always pumped my bike until I felt the wheel was firm, as I had never heard of psi or anything. How do you exactly tell how much to pump your bike and what does psi have to do with anything?
