The invention relates to a multipurpose transformable rickshaw which comprises a transformable rear frame and a drive device for driving rear wheels. The transformable rear frame comprises a left rear framework, a right rear framework, a left rear turning rack and a right rear rack, wherein each of the left rear framework and the right rear framework comprises two parallelogram mechanisms disposed up and down, the front-end short edges of the four parallelogram mechanisms are connected with a connecting rack, the rear-end short edges of the two parallelogram mechanisms of the right rear framework are fixedly connected with the right rear rack, the rear-end short edges of the two parallelogram mechanisms of the left rear framework are connected with a C-shaped rack, the upper frame of the C-shaped rack is connected with the upper frame of the left rear turning rack through hinges, and wheels are mounted on the left rear turning rack and the right rear rack. The multipurpose transformable rickshaw has the advantages that transformation between a bicycle and a tricycle is achieved simply and fast through the parallelogram mechanisms of the rear frame, the problem of interference of a traditional bicycle chain on the movement of the tricycle after transformation is solved through shaft transmission, and the rickshaw is convenient in transformation, novel in structure, environmental friendly, and wide in practical value.
