they are all just bicycles. saying 'city bike' means nothing to me. there is a beautiful but mildly loved vintage pinarello i see locked up outside the coffee shop near my brothers condo all the time. its appearance coincides with the same mid 20s 'hipster' baristas apparent schedule. so guy lives in the city and commutes on said bike to work. there, city bike. doesnt fit previous description.
meh.
