The structure generally includes first and second seat post members which are articulable about an axle pin, an interlocking element engageable with a locking element to provide selective adjustment of the seat post members relative to each other and a housing surrounding the mechanism. Horizontal adjustment structure generally includes a slidable arm positioned within a bracket, and the bracket is attached to one of the seat post members. The rotational and horizontal adjustments provided by the structure of the invention can be accomplished in a matter of seconds while the rider is seated on the vehicle.
