ABSTRACT:
Cycling apparatus including pivoting handlebars that permit a rider to move the handlebars into either a drop or aerodynamic riding position, or any comfortable riding position therebetween. The apparatus comprises a cycle having a body, a housing is coupled to the body, and first and second handlebars are provided that are used to steer the cycle. Rotating apparatus is coupled to the housing and to the first and second handlebars for rotating the handlebars in unison. The handlebars are rotated between a first position wherein the handlebars are generally orthogonal to the body of the cycle and a second position wherein the handlebars are generally aligned with the the body of the cycle. The rotating apparatus may comprise first and second interlocking gears, a flexible drive coupling, a set of universal joints, or any similar rotating device that permits the handlebars to rotate between the desired positions. First and second brake levers are disposed adjacent respective distal ends of the first and second handlebars adjacent a rider's hand positions. First and second gear shift levers are also disposed adjacent respective distal ends of the handlebars adjacent the rider's hand positions. Forearm pads may be disposed on a portion of the cycle to which the housing is attached. The pivoting handlebars pivot in unison to permit different riding positions while the cycle is in motion.
