Engineering bicycle locks

  1. Sep 18, 2004 #1
    Here is a common engineering problem. How do you engineer a bike lock that cannot be easily picked? High-quality video footage circulating on the internet shows how at least some cylindrical locks can be picked in about one second with the hollow plastic main tube of a standard Bic pen.

    Perhaps an oval shape instead of circular.
