The invention mainly provides a height adjustment cable-control structure of a bicycle seat stem, which comprises a seat stem unit disposed in a bicycle seat tube, a cable-control brake unit disposed in a pre-set position of a bicycle frame, and a lever reset unit located between the seat stem unit and the cable-control brake unit. The cable-control brake unit is disposed in the pre-set position of the bicycle frame and provided with a cable wire. One end of the cable wire extends to the inferior of an outer tube, and the other end is connected to a rotational handle and driven by the rotational handle to generate a pull action. By means that the pre-set position of a second lever body can support a first lever body after proper rotation, and the first lever body pushes a valve stem upward to open an oil path after rotation, a reset unit is cooperated to provide an elastic force for the second lever body after the rotation of the second lever body due to the cable wire traction, and a cycle reset is generated so as to achieve smooth in use, to reduce change and maintenance, and to have safety and compatibility, and meanwhile a cost problem caused by purpose made standard is avoided.
