Abstract
A bicycle seat includes an upright post, a support base mounted on an upper end of the upright post, a rotation base rotatably mounted on the support base, a seat body movably mounted on the rotation base, a retaining member mounted on the seat body, and two locking bolts in turn extending through the support base, the seat body and the retaining member to clamp the seat body between the rotation base and the retaining member. Thus, after each of the two locking bolts is unscrewed, the seat body is movable forward and backward relative to the upright post so as to adjust the position of the seat, and is rotatable relative to the upright post so as to adjust the inclined angle of the seat.
