A fixed block is mounted in the seat tube above the block, having an upper side and a lower side to which a distal end of the adjusting bolt is securely attached. An upper block is slidably mounted in the seat tube above the fixed block. A spring is mounted between the fixed block and the upper block. A seat post is received in the seat tube with a bottom end thereof resting on the upper side of the movable upper block. A transverse bore is formed in the seat post at a section above the seat tube. A seat mechanism includes an upper ring element, a lower ring element, and a pair of guiding rods extending therebetween. A balance rod passes through the transverse bore in the seat post and has two vertical holes through which the guiding rods pass. The lower ring element has inner threadings to engage with threadings formed on an outer periphery of the upper end of the seat tube.
