The B.Y Handle Lock is an oversimplified lock for cycles. An extending wire from one end of the handle loops into the tire of the cycle, and is secured via a number lock on the other side. A few points of refinements come to my mind, like the wire should be made retractable so that coiling it back into the handle shouldn’t be a hassle. The other point is of course, the wire should be heavy duty so that it can be secured to a fence or a tree. Otherwise, it’s a pretty neat idea, what do you think?

B.Y Handle Lock is a 2011 iF concept design entry.
