A bicycle seat adjustment device includes an adjustment device connected to the second end (122) of the inner tube (12) and a first clamp member (21) is fixed to the second end (122). An adjustment rod (22) movably extends through the first clamp member (21) to define an adjustment distance formed between the first and second clamp members (23). An expansion member (24) and a resilient member (25) are mounted to the adjustment rod (22). The expansion member (24) is located in the adjustment distance. The first and second clamp members (21, 23) respectively contact two ends of the expansion member (24) so that the expansion member (24) having its edge (242) contacting the inner periphery of the outer tube (11). A control device is connected to the clamp unit (13) and has a lever (33). The control rod (32) is connected between the lever (33) and the adjustment rod (22).
