I bought my bike on e-bay. And e-bay do warn you of scammers who tries to redirect you away from e-bay onto the scammers web site even though the page looks like e-bay. Check to make sure you are still on e-bay site and paypal site cause some of them make the scam page look almost like e-bay's or paypal's page.

I've seen several scams on e-bay for bikes. One redirected me to a porn site (shaking my head) I showed how it happened to my partner to make sure I wasn't seeing things and within two three minutes, e-bay had shut it down. Pretty quick or I just caught the tail end of things. Either way, e-bay really does spend lots of time ferretting out the scammers. So I don't mind the extra they charge me when I list something. My partner is a power seller so she has seen lot more scams. She reports every single one. She never gets a reply from e-bay but the scam disappears quickly. Nice to know still gotta be careful.
