Abstract: In the method of adjustment a bicycle seat assembly the driver is rotatable in the first and second directions. Upon rotating the driver in the first direction, tightening of the connection between the bicycle seat, the seat post and the adjusting member causes simultaneous adjustment of the wedge sub-assembly provided at the interface between the distal end of the adjusting member and the seat post. Rotation of the fastening driver in the second direction causes loosening connection between the seat post and the elongated adjusting member and causes simultaneous loosening of the wedge sub-assembly.

Abstract: The cycle seat with adjustable sides includes a base plate having a forward and optionally a rearward guide plate thereon. Each guide plate includes laterally adjustable left and right arm extensions, with each arm having a generally vertical wing extending upwardly therefrom. The arms of each pair simultaneously adjust inwardly and outwardly opposite one another, permitting a single adjustment to adjust both wings of a set equally. Each wing pair includes a latch mechanism, which is adjustable as the cyclist rides the cycle. The seat may be installed per se upon a bicycle or other cycle, or may be installed in combination with a longitudinal and/or arcuate and vertical adjustment mechanism for the seat. The cycle seat greatly reduces or eliminates the need for a pommel, while assuring that the seat remains in contact with the hips and/or thighs of the cyclist at all times to assure more complete control.

Abstract: A seat post axially slides into an insert sleeve that fits into a bicycle frame in the place of a conventional seat post. The seat post has a long keyway along the front and a narrower keyway or tubular section along the posts back. Along the inner wall of the front keyway is a plurality of holes sized to receive a locking pin. Connected to the inner wall of the insert sleeve is a support key unit that slides within the front keyway of the seat post, as the seat post is moved up and down. In the support key, the height adjusting, locking pin is housed as well as a hanger is formed where one end of the elastic spring is attached. The elastic spring is then brought around a pulley positioned within the bottom portion of the seat post, brought up the rear keyway and is attached at the top of the seat post in a downward pointing hanger. The elastic spring acts as if it were attached from the bottom of the seat post to the bottom of the support key.
