Is the metal part really that skinny? In some places i have to get off my bike there are also not many opportunities for my two u-locks, but I practice while riding looking out for objects which seem to fit a u-lock. With some phantasy I always find something to lock my bike onto. For example we've got those street lanterns here, whose diameter decreases from bottom to top. No way to lock a bike onto from bottom to a height of 1.50 meters. But after that height, a Kryptonite Evolution will fit around. Some other lanterns require it to hang my bike with the ulock onto the lantern, so it doesn't even touch the ground...
