There's a cycle-shop on the other side of town from me that takes donated bikes. I used to volunteer out there all the time. It was great because if you found something you got it for it's cost in scrap! Now I help the local scout troop collect donations for them twice a year and I get first pick on all the bikes. Haven't seen anything great come through in a while though. One year a Schwinn Le Tour came through in almost new condition. It wasn't my size and I didn't know anyone looking for a bike at the time so I didn't pick it up but I seriously debated it.
