All of those are scammers. I've seen it before. Foreign scammers. Anytime stuff is worded that funky, just delete it. Sad, but true.
Typical CraigsList and eBay crooks.
A proper American responder will say, "Hi! Nice bike! I'd like to come by to see it. Let me know what day is convenient, or may I have a contact number." Or, "Hello, may I see some high res pics? My e-mail address is xxxxxxxxx."
Funky sounding is scammers. If they talk like you, short and sweet, probably OK.
