Unfortunately, there is no way to hang the bike up on the wall hooks and lock anything but a wheel to the cage using a u-lock. Maybe a thick chain? If I had known the cage was more useless as locking out on the street I would have opted for a larger apartment. Right now, I would need to throw away furniture to have anywhere to put a single bike, let alone 3.
Did the management of your building do anything in response to the mass theft? 20 at once seems like it would require some amount of police investigation?
