I'm of the mind to clean up the bike rental stations in Europe question. It has grown out of proportion and is barely useful. I don't want to delete it outright, it still can be useful, if updated occasionally (realistically though, probably not going to happen).
Basically, create one answer with a laundry list of cities grouped by country, with little to no additional information for each (besides a link, obviously), to keep it short. All other answers will then be deleted -- they are community wiki, so no reputation change will take place anyway.
Thoughts? Suggestions what to include and what to omit?
If no one objects, this will be taken care of in a week or so.
Update: The question is now locked, but not deleted, with a note on its historical significance.
