Pasty Bike

A bicycle used for (but not exclusively) the collection of pasties and pies either for an individual but often a conglomerate of friends or colleagues.

A pasty bike is generally fully functioning, albeit with a slightly dull or dishevelled appearance, such that it could be left unattended outside a public house or bakery with no fear of it being stolen. Handlebar baskets and a bottle carriers are recommended but not compulsory.
Also used for single or return trips to the pub, confectionery collections and other low profile trade deals.

2) "see that shitty looking bike lay outside the pub?"
