Abstract
A pivoting seat system that enhances performance, convenience, safety, and the general appeal toward comfort as well as control of targeted muscle groups to exercise. The stationary bike, recreational, and avid professional bicycle rider can utilize this system as it maintains proper seating positions and optimum leg pedaling lengths throughout its rearward movements, and also offers both rearward and forward seat clearances while standing on the pedals in adverse terrain conditions, such as varying downhills, and downhill with obstructions, turns, curves, etc. The seat locking and releasing system is controlled by activation of a release lever on the handlebar, and is body weight driven in the rearward positions and spring loaded toward movement in the forward positions. Its unique parallel bar technology allows for the seat to remain in the same orientation throughout all its desired positional movements.
