A shock-absorbing and height-adjusting assembly for mounting a seat (34) onto the seat-supporting framework tubing (12) of a bicycle frame (10). A gas spring (14) is slideably contained within a hollow receiver (15, 16) attached alongside or within a lower portion of the bicycle seat supporting framework (12) to which the gas spring piston rod (18) is affixed with the upper end of the gas spring (14) in contact with a vertically extending seat supporting guide tube (19) supported in alignment with the gas spring (14) for movement within a bushing assembly (21, 22) affixed to the uppermost portion of the bicycle seat supporting framework (12). A push rod (33) slideably contained within the guide tube (19) for vertical movement between a raised position with the push rod (33) lower end overlying a top mounted gas spring actuator (32) and a lowered position in operational contact with the gas spring actuator (32).
