Apparatus for shock-absorbingly supporting a bicycle seat (50) on a bicycle frame (12). A longitudinal beam device (43) is pivotably attached via transverse bearings (48) at a first end (45) to the frame (12), the beam bearings (48) being configured to permit pivot motion only in a plane containing the bicycle frame (12). The beam device (43) is supportive of a seat (50) near an opposite end (54) of the beam (44). Shock-absorbing device (56), preferably an adjustable gas strut, is disposed below the beam (44), a nd is connected at a first strut end (58) to the frame (12) and at an opposite strut end to the beam (44) adjacent the seat (50) to form a triangular strut shock-absorbing suspension for the seat (50) wherein the triangle side comprising the strut (56) is variable in length. In a preferred embodiment, the length of the strut (56) may be remotely adjusted (60) by the rider to vary the distance between the seat (50) and the pedals (35) or ground (61). In a further preferred embodiment, the beam device (43) includes a control (74) to adjust the attitude of the seat (50) in accordance with the height thereo f. In a still further preferred embodiment, the load operating range of the str ut (56) may be varied to accommodate different riders of different weights.</SD OAB>
