Abstract
Abstract The Extended Elevated Foot Platform (EEFP) is an invention that is attached to the rear of a conventional skatingmobile. It is comprised of a pivoting arm, pivoting arm assembly, foot platform, pivoting pin, pivot pin keeper and foot brake. The rider of a skatingmobile is able to propel the skatingmobile by standing on the EEFP, holding onto the handle bar of the skatingmobile and shifting his weight from side to side, thereby negating the need to push off the ground for propulsion.
