Most cable locks consist of a long cable with two loops in the end plus a padlock. It's always more secure to lock the bike to something, with the cable passing between both tires, but sometimes, say when wanting to attach the bike to a wrought-iron bench, the cable won't reach far enough. Then you can use this trick, and there are two variations:
1) Put the cable through the hole or around the object you wish to lock to, put one eye of the cable into the other, and pull tight. Now you have nearly the entire length of the cable available for use. Put the cable through the front wheel, and then the frame, circle around the rear tire and the main tube, and finally lock the cable eye to the cable on the other side of the tube. If the cable is not quite long enough for this, just lock the cable eye to one of the stays.
2) Loop the cable around the main tube and rear tire, put one eye of the cable into the other, pull tight, and then take the cable through the front wheel of the bike to whatever you want to lock it to. There you can loop it as before to lock.
