Abstract: A convertible trailer assembly is provided that can be pushed or pulled. The trailer assembly can be converted between pushed or pulled operation or provided as a retrofit assembly for a stroller that allows its conversion between pushed or pulled operation. The Assembly includes a linkage assembly to provide a smoother towing experience for the user.
