Something very Brideshead about a well dressed gent cycling along on a sit up and beg bicycle. I suspect it would work best in a market town or a university town. In my youth I had one like that which had I salvaged from a scrap yard. It weighed a ton and had brakes that could best be described as sketchy, going downhill was 'exciting' and required a clear path, going uphill was killing.

Realistically you are going to look a mess after you have been on the bicycle because of the wind, a 'sit up and beg' bicycle gives you the aerodynamic properties of a housebrick and the hairstyle of Boris Johnson. A fun image if you can pull it off without looking like an iGent though.
