be the high bidder and go have a look? It might be a bit awkward when you walk away without paying if it isn't your bike - good excuses include: setting your phone alarm and pretending to answer it and saying you have to attend an emergency, forgetting your wallet, saying it isn't as described (won't be too difficult, given there is zero information)
Might be others but I can't think of any right now
