ABSTRACT:
A hollow seat post has a seat attached at one end while the opposite end is split defining an aligning pin receiving groove. One portion of the split end is provided with longitudinally spaced pin receiving holes. A coil spring is inserted inside a frame seat post. A small pin extending through the bottom of the frame seat post serves as a stop for the coil spring. A second pin extends through the upper portion of the frame seat post and aligns the seat when the seat post is inserted inside the frame seat post with the second pin in the groove in the seat post. A lever actuated pin is mounted on the frame and is positioned so the pin is in alignment with a hole extending through the frame seat post and can move therein. When the seat post is inserted in the frame seat post and the hole in the frame seat post is aligned with one of the holes in the seat post, the lever actuated pin penetrating both holes holds the seat at the desired level.
