A foldable frame (100) for a tricycle (1000) powered by physical force and/or a motor; the frame (100) having a number of subframes interconnected to fold the component members of the frame (100); and the folding of a central subframe (10) of the frame (100) causes two lateral subframes (30) supporting the rear lateral wheels (W1) to fold from a first fully unfolded position to a second fully folded position, and vice versa.
