Abstract
A seat post assembly includes an outer tube and an inner tube movably disposed upwards and downwards in the outer tube. A bushing has an upper sleeve disposed on the top end of the outer tube and penetrated by the inner tube, and a lower sleeve movably mounted upwards and downwards on the inner tube. A connecting structure is disposed to the bushing for enabling the lower sleeve to be connected with the upper sleeve and moved along the axial direction of the outer tube relative to the upper sleeve. Further, the connecting structure allows the position of the lower sleeve relative to a protrusion of the inner tube to be adjustable. As such, when the bottom end of the lower sleeve is abutted against the protrusion of the inner tube, the inner tube cannot be raised to achieve the effect of adjusting the total height.
