Abstract: A child's bicycle seat is set forth wherein an elongate split post is securable to a horizontal support shaft of an associated bicycle with forward arcuate legs surrounding an associated forward steering post of the bicycle wherein the arcuate legs terminate in securement legs oriented generally parallel to one another to receive a threaded fastener therethrough. The cylindrical seat support shaft includes a rear downwardly depending plurality of tabs for securement of a further fastener with a medially positioned downwardly depending pair of flanges spaced between the rear tabs and the forward arcuate legs secured integrally and orthogonally downwardly from the seat support shaft with an aligned pair of hexagonal apertures therethrough to receive a hexagonally cross-sectional configured bolt. The hexagonal bolt is directed through one of a series of hexagonal apertures through foot brackets to enable the foot brackets to be rotated for height and orientation relative to the seat.
