I agree it's a scam. If you go forward you will find that the money does not end up in your account, rather you will get a sort-of-official-looking thing from a supposed escrow service where the money will theoretically be released on proof of shipment. I got that far with a camera and realized i was being had. weeks later i was still being dunned by email.
The camera i was supposed to ship to africa but i actually don't think they want the camera or the bike. At some point in the sequence they would get some modest amount of money from you and slink away leaving you covered in poop and shipping fees.
