LOL!
I can see your point. Personally I wouldn't want to own any uber niche porn bikes on this thread (I don't watch porn either thanks…), I just think that to qualify as bike porn it needs to be different to the usual mass-market offerings, even if it's been lovingly custom built by the owner (as that On-One obviously had been) but I can admire the bike porn for what it is.
I'm never really bothered what someone actually rides, it's all people on bikes and that's (usually) a good thing. The whole point of bike porn is to say "ooh, that's new/different/niche/aesthetically pleasing" but then to go and ride your own bike. None of my bikes fit the description of bike porn – they're all custom builds and (to me) they're very nice but they're just bikes, no-one would look at them and go "phwoar" which is surely the whole point of bike porn?
