Buying my first bike

I've been in living in PGH for about 5.5 years, and I've recently been thinking of getting a bike for getting around because I don't have (or desire) a car. Do you have recommendations for bike shops to check out for my first bike? I live near Squirrel Hill. I've heard good stuff about Free Ride PGH for cheap used bikes - anyone have experience with them? Also would appreciate any advice for a new city cycler!
