I'm thinking about building an "English beach bike," using a classic English 3-speed frame and hubs, but with 559 rims and Schwalbe Fat Franks or Big Apples. From a utilitarian perspective (riding near, but not on, the beach, with lots of soft sand and grass), it would seem to make sense -- like a beach cruiser, but with better geometry and gearing. But I've never actually seen it done. Does anybody have an example you'd like to show off? Can you say just how wide a tire one can put on a 23" Raleigh Sports? Thanks!
