OP this all smacks of middle-class paranoia TBH…
Generally if I photograph anything going up for sale, it has to wait until the dead of night, once the kids are down, We’ve had some food, I’ve tidied the garden a bit, and I’ve tactfully excused myself from watching whatever reality tat the missus has stuck on the TV…
There are 24 hours in the day, some people actually make use of the darker ones when you’re tucked up in bed…
Seems like you’ve decided the seller is up to no good without much actual evidence…
Like most PB buy/sell posts its clearly just a bike assembled from used parks/spares, with an advert that falls well below STW standards of spelling, literacy, photography and Mobile phone Skillz, but that’s par for the course on Pinkbike… Sorry.
Anyway standard practice on PB or RideIO is to ask if He’ll consider splitting, because you’re only interested in the rear skewer and maybe the washers from under the bottle bosses… nobody ever buys a whole bike on there.
