A bicycle seat post height adjustment mechanism, in a state of locking, has a lower valve packing ring blocking a lower valve port. Moreover, based on demands, an upper valve packing ring is allowed selectively to block an upper valve port or to be away from the upper valve port to stay on top of the upper valve port. Thus, a pin is driven to axially move down to enable a seat post to make fine adjustment, stepless adjustment or stepped adjustment in height. Moreover, the seat post may self-return to the assigned position (an upper position, a middle position or a lower position) to prevent the height of the seat from altering.
