Cycling in Sydney Australia
Montreal has parking meters for bikes in the CBD. They have a loop secured to a pole to lock the bike to. They are about every 10-20 meters and they appear to be well used. Most seem to have very robust locks. There seemed to be a lot of cyclists in the city and appeared to be accepted as a part of the traffic. I haven't seen any signs of aggro towards anyone. Such a charming city!
Does the parking cost more than the value of the bike :)
I would speculate that this is just a standard parking meter (actually just a parking space identification marker) for motor vehicles with the addition of a free securing ring for bicycles so cyclists can really get up the nose of motorists by reminding them that they get it for nothing ! A better design would have placed it slightly further out from the wall so another bike could be secured on the other side
