I am kind of struggling with the cycling world. I am poor. I wanted to start riding for exercise and to commute to work. I didn't realize how much fun it was going to be! Now I want to learn all sorts of things about cycling but everything seems very geared towards buying things, taking your bike to get tuned, having computers etc.

Are there any other poor cyclists out there who got a bike from a garage sale and are trying to figure out where to buy cheap cycling shorts? I almost got sick when I went into a bike shop and saw how much they cost. I was thinking maybe I could afford 20$

Any tips would be so appreciated. I feel alone.
