摘要： A wheel-supported cart or trailer is removably attached to a bicycle seat post by pullbar means attached to the front end of the cart and a hitch encircling the bicycle seat post. The hitch comprises a separable rigid metal band encircling the bicycle seat post with an interior bushing made out of a relatively stiff but resilient material, the bushing having an inner lip which makes encircling snug contact with the bicycle seat post. The trailer wheels are mounted on each side of the trailer by their own separate axles but in a manner to support the trailer across the underside of the trailer.
