High performance lock mount and method

A method for releasably securing a lock comprised of a U-shaped shackle having an open end and a cross-bar connected across the open end thereof to a bicycle at the steering control portion thereof characterized by the intersection of a first frame member and a crossing second frame member, the method comprising the steps of:

• releasably securing a first mounting block to the first frame member, said first mounting block having a first concave mounting surface of a predetermined first axial length in which a portion of the cross-bar is cradled and an opposing second concave mounting surface of a predetermined second axial length located below said first concave mounting surface in which a portion of the first frame member is cradled;
• releasably securing second and a third mounting block to the second mounting block crossing frame member, on opposite sides of said intersection said second and third mounting blocks each having a first concave mounting surface of a predetermined first axial length in which a portion of the shackle is cradled and an opposing second concave mounting surface of a predetermined second axial length located below said first concave mounting surface of each of said second and third mounting blocks, respectively, in which a portion of the second frame member is cradled;
• said first and second concave mounting surfaces of said first, second and third mounting blocks each being positioned relative to each other so that the direction of said first axial length is transverse to said second axial length for each of said first, second and third mounting blocks, respectively;
• releasably securing the cross-bar to said first mounting block;
• and
• releasably securing the shackle to said second and third mounting blocks.
