Snobbery does exist everywhere despite trying to repress it or ignore it. Most on here, me included, comment on BSOs etc.
There's a bloke who I see regularly, or at least his bike, as he goes into the same Tesco as is on my route to work. It's a "Seasure" folding mountain-style bike (not as bad as the folder in my other thread as it doesn't pretend to be something its not, basic functional equipment rather than novelty-looking stuff that doesn't work)
Fitted with an old-fashioned front basket the guy gets his daily shopping, hangs it on the front and pedals off in all weathers.
Is he riding a BSO? - well, yes, many would term it a BSO
Is he a "proper cyclist"? - daily use of the bike to get around - of course he is a "proper cyclist"
I make the assumption from his bike that he doesn't do anything other than commute, but then, he could have a £5000 machine wrapped in cotton wool at home for weekend use, who knows? More to the point,does it matter?
