A wheelchair transport system and apparatus enables users to transport a wheelchair by way of a motorized, tadpole-configured tricycle. The wheelchair transport apparatus includes a main frame, a pivot assembly, and a lever arm assembly. The main frame includes an elongate frame member that attaches to a motorized tricycle. The pivot assembly includes pivot arm and chair support assemblies. The pivot arm assembly includes two pivot arms pivotally attached to the main frame. The chair support assembly includes two support members pivotally attached to the pivot arms. The lever arm assembly is attached to a forward pivot arm. Together, the lever arm assembly, the pivot arms, and the support arms are positionable intermediate a lowered position and a raised position. The raised positions enable the user to transport a wheelchair as supported upon the support arms.
