Here is a pic I found on the web of bike parking at my office. There are 24 of these crankcase bike locks at my building alone and I have never seen more than three of them in use at any one time. There must be a tax credit for putting these in or I don't know why they put in so many. They are great though. I can secure my bike with only a padlock. It’s nice not to have to carry my U lock.
