Depending on the diameter of the pole, sometimes I can fit the Kryptonite mini around frame+wheel+pole. Most of the time however I cannot fit the wheel and resort to using a secondary lock to lock the wheel to the frame.

I've observed that a lot of people in the city use locking skewers on their wheels and simply carry the mini-ulock in their pocket b/c it is so convenient and does not require an extra bag or frame mount. That seems to be the ideal way. You can still carry a second lock for peace of mind, but you don't have to worry about fitting the mini around your wheels this way.
