A Telescopic and Variable Tilt Bicycle Gooseneck handlebar system designed for bicycles of all types. A pivot base, pivot arm, hollow stem and truss axle allow for easy adjustment of bicycle handlebars. The design implemented herein allows for the bicycle handlebars to be raised and lowered as well as tilted towards or away from a rider of the bicycle. Raising the handlebars is accomplished by raising and lowering the hollow stem through an opening in the pivot arm. The handlebars are tilted by disengaging the truss axle thereby allowing the pivot arm to rotate laterally with respect to the mounted pivot base.

[What is claimed is:] [1.]a hollow stem having a first end and a second end, the first end suitable to receive a circular member of lessor diameter than the hollow stem, said circular member being a handlebar post;a pivot arm including a circular opening through which the hollow stem is inserted;a series of apertures spaced equidistance along a length of the hollow stem;a position pin inserted through a bored hole in an outer edge of the pivot arm at a position radially adjacent to the pivot arm opening such that a first end of the position pin extends into the pivot arm opening and further extends into one of the apertures in the hollow stem thereby securing the hollow stem in position, a second end of the position pin attached to a lever arm positioned at an outside edge of the pivot arm, a first end of the lever arm being rotatably connected to a mounting pin extending from within the pivot arm, a second end of the lever arm being held in place by a coil spring, a first end of the coil spring attached to the second end of the lever arm, a second end of the coil spring attached to a bolt screwed into the pivot arm at a position radially adjacent the pivot arm opening;a rod with a first end connected to the lever arm at a point near the second end of the lever arm, a second end of the rod connected to a first knob handle;a means for pivoting the pivot arm with respect to a pivot base;a nut and bolt assembly for mounting the pivot base to a bicycle frame.
