ABSTRACT:
Disclosed herein is a bicycle seat assembly designed for optimal comfort and riding efficiency. The assembly includes a forward, upward extending, rigid support member adjustably attached to the seat tube on a bicycle. In one embodiment, the support member has an adjustable collar assembly which enables the support member to be attached to a standard seat post which is inserted into the seat tube. A v-shaped, extension arm is pivotally attached to the support member. The extension arm may be rotated between a rearward extending position and a forward extending position. The standard bicycle seat, called a primary seat structure herein, is attached to the top surface of one leg segment of the extension arm with a secondary seat structure is attached to the rear surface. When the extension arm is disposed in the rearward extending position, the primary seat structure may be used for normal riding. When the rider climbs an incline surface, the extension arm is rotated forward in a counter-clockwise clockwise direction to the forward extended position. In the extension arm is disposed in the forward extended position, the secondary seat structure is disposed in a position to support a rider in a standing position. The distance of the secondary seat structure is sufficient so that pedal distance is maintained for full leg extension.
