For years there has been one prolific scammer in ebay aiming at expensive products but so low it's too good to be true. Almost always it has been adverising 180 items plus. if you start to look at the items as dukesox mentions, they will always be in multiple different background locations in the photo.
He used to advertise that he could deliver the item, most people will say yes unless local but they arrange a delivery after transferring sums and the bike never turns up.
This is the company he is claiming to be, genuine company in Lincoln but he's hijacked company logos.

The telephone number advertised for the genuine is 01522 721010, the diverts contact number is 0 152 243 7508. As most will have experienced, scammers from outside the U.K can now ring you from area codes in the U.K.
They normally hack into peoples ebay accounts by you asking them a question in ebay, they say send any enquiries to his personal email account, you reply to it and then he replies with a key logger bug.
If it's something you want but are unsure, ring the account but turn off your number i.d. and ask to see the bike, excuses are likely to follow
