A bicycle seat adjusting assembly includes a seat tube having a bore extending transversely through an upper part thereof, a balance tube received in the transverse bore with two ends thereof exposed outside the transverse bore, a mounting member adapted to hold bicycle seat supporting rods therein, having an arcuate bottom surface pivotally received in the arcuate surface in the upper end of the seat tube and two ears each with a vertical hole therein in alignment with a vertical bore in each of the exposed ends of the balance tube, a positioning block mounted on each ear and having a threaded hole in alignment with the associated vertical hole in each ear, and an adjusting bolt passing through each vertical bore and associated vertical hole to engage with the associated threaded hole. Rotation of the two adjusting bolts in opposite directions causes a change of the inclination of the bicycle seat supporting rods.
