Different people cycle for different reasons. You need to decide why you want to cycle and do what you want.
I cycle primarily for pleasure. I enjoy cycling. Everything else is secondary to me.
I do not cycle to race, train or to build my stamina. So I am not interested in figures like speed, cadence, heart rate etc etc.
I wear what is comfortable for me. They are mostly from Aldi and
Decathlon B Twin. It is nothing to do with affordability.
I do have 3 different bikes for 3 different purposes.
Regarding hills, I am happy if I get to the top, What speed I get there is not so important for me.
So, ignore comments and just enjoy cycling.
