A seat stem adjustment device includes a seat stem received in an outer tube, a control unit connected to a bicycle frame, and a leverage unit located between the outer tube and the control unit. The control unit has a cable which is connected to and driven by a lever. The leverage unit has a top member connected to the outer tube. A first link and a second link are pivotably connected to the top member. The first link contacts the valve rod. The second link has a mediate portion pivotably connected to the top member. The second link is connected to the cable. A resilient member is connected between the top member and the second link. The second link pushes the first link to open or close the hydraulic liquid path when the cable is operated so as to adjust the height of the seat.
