IMPROVED BIKE RACK FRAME CLAMPS, SYSTEMS AND METHODS

A quick-release clamp for a vehicular mount or rack having a rigid stationary first jaw with a clamping surface, and a rigid second jaw opposite with a clamping surface oriented to face the first jaw clamping surface. The second jaw is movable between an open and a closed position relative to the first jaw, where the closed position is capable of retaining one or more objects to be clamped transversely between said jaws. A lever, attached to a variable tensioning system operates to open and close the jaws when sufficient force is applied to overcome the tension of the tensioning system.
