And the Schwinn store would have told him what? Likely: "Take that $^$#@ off of there" or something similar. Does this mean I think he actually called a Schwinn store? Hardly.
My gut instinct (i.e. my opinion) is that I agree with you. This stuff's been stolen and he's desperate to unload it fast. I would be quite surprised to learn otherwise. If he truly knew anything about that motorized bicycle he'd know you don't "call the Schwinn store".
