One of our LBS in conjunction with a club that gets together and repairs the bikes in the fall before Christmas, than gives them to kids who need a bike. Typically as my kids grow out of bikes we donate them to a children's services agency where my wife works, but most countys will have a children's services agency. Goodwill is OK but I know for a fact my bikes are given to children who would otherwise not have a chance at any price, and have seen them in use by kids with huge smiles on their faces!
