I wonder if we could extract all the OSM nodes with shop=bicycle ?
Good call.
Theres lots of scope for an Audax POI dataset detailing:
Bike Shops (and Halfords!)
Post Offices
Superstores & express stores (incl. garage sites).
Village stores, Tea rooms, Cafes, Chippies....
Much of this information is kicking around the web in one form or another. Using OSM as a common repository from which POI datasets could be generated may well be the way to go...
