Questions & Answers about kuukiatsu o kakuninshite, nando mo shijoushita sueni, dendouashisutojitensha o katta.

What does 空気圧 mean here? Is it specifically the bicycle tires?

Yes. 空気圧 literally means air pressure, and in this context it most naturally means the tire pressure of the bicycle.

Japanese often leaves out words that are obvious from context, so instead of saying something like タイヤの空気圧, the sentence just says 空気圧.

Why is 確認して in the て-form?

The て-form is being used to connect actions.

So 空気圧を確認して、何度も試乗した末に、...買った means something like:

checked the air pressure,
and then test-rode it many times,
and after all that, bought it.

Here, 確認して links the first action to what follows. It does not necessarily mean the actions happened immediately one after another, just that they are part of the sequence.

What does 何度も mean? Why is there a も?

何度も means many times or over and over.

The も adds the sense of repetition or emphasis. Compare:

何度 = how many times / how often
何度も = many times, repeatedly

A very natural English translation here is after test-riding it many times.

You will also often see 何回も, which is very similar.
