I've only had one box store bike... it came with no wheels and a busted front ring shifter, it was a Schwinn High Timber or some such nonsense.. but it was a solid dependable bike after I got a wheelset/shifter on it and I even used it as my worktime beater/trail beater for quite a few months.. ended up giving it away to a friend who is now using it to get back in shape. If you want to invest some time and care into it, and it's high enough box store quality it'll make a great disposeable beater or indestructable beater depending, but it's not gonna be worth reselling even if all you have to do do is clean it up for an hour.
