ABSTRACT:
A bicycle assistive handlebar structure installed at the anterior extent of a front fork stem, stem clamp mount that serves as a means of conjoinment. The stem clamp mount consists of a concave section and a threaded hole that provides for the fastening of bolts inserted via four through-holes. Furthermore, a vertical coupling passage is disposed through the installation crown, thereby providing for the horizontal arrangement of a handlebar in a connective mounting shank. The two sides of a transverse rod provides for the fitting into position of insertion sleeves, and an elongated hole provides for the stationary seating into the connective mounting shank elongated hole. Radial splines are respectively fabricated along the outer sides of the joint mount and the inner sides of an assistive handlebar. As such, the present invention provides the rider variable adjustment operation over upper and lower height, forward and backward distance, and rotative direction.
