Here are a couple bike shops that I've recommended to students in the past. Can someone please post if they've had any experience with either of these stores? I don't want to continue to refer people to places that aren't actually very good. Thanks!
These folks have been in business for a while and have moved to a larger facility in the last couple of years. They do recycle bikes and I think have a decent selection.
This place seems like a really neat spot to pick up some used wheels at a very friendly rate, but I can't vouch for how helpful this place is because I've never been there.
I was driving by the ReTAG It store yesterday and noticed they have a number of used bikes for sale--they were out on the sidewalk. This could also be a good option for an inexpensive bike.
They also maintain inventory online so you can check it out before you go.
