Spied this on Gumtree and of course it may be genuine but just in case

It looks brand spanking new and never ridden plus the blurb is obviously a direct copy and paste from a shop's site. I'm not sure what year that is but a brand new full bike is £4k+. If it's not stolen then it's a bargain.
Sounds like it might be a shop selling it?
it'll be a scam... no contact number, only way to get in touch is by email. So send one off to them expressing interest, bet you'll get a reply back along the lines of ' I'm overseas, please pay me via this genuine escrow account and I'll send the bike to you'... lots of these on Gumtree, they must have success with it, otherwise why bother?
Just looks like a shop ad. Doesn't look like that much of a deal either, average spec at best.
Not much of a deal? 😕 You can barely buy the frame for that price.
