Not the iconic high-wheeler.
In the show, very often in the background can be seen a denizen of The Village riding a 20" or so wheeled bike. Only glimpses of it, no close-ups. My eye is not very trained to spot folders or smaller-wheel probably English bikes, but it appears to be a Raleigh 20, or one of those other Moultons, like Bridgestone is doing, with the big tube instead of the space frame. Interesting features include front and rear rack... and of course the awning.
Anyone know for sure what bike it is?
