A powered personal mobility vehicle for transporting an infirm occupant includes at least three wheels configured to contact the ground, at least one electric motor, a frame, a lower seat post coupled to the frame and extending upwardly from the frame, a modular suspension unit supported by the lower seat post, and a seat assembly supported only by the modular suspension unit. The modular suspension unit includes a post assembly that includes an outer post slidably coupled to an inner post, and a dampener located completely within the post assembly. The modular suspension unit is removably coupled to the lower seat post and is configured to be removable from the lower seat post as a unitary assembly. The outer post, the inner post, and the dampener are configured to dampen vertical movement of the seat assembly relative to the frame in response to impact between the wheels and the ground.
