Abstract

An unusually light bicycle trailer which may be readily collapsed for shipping, transportation, and storage. The trailer employs a hitch which not only is unusually quickly attached or unattached from a bicycle, but additionally is so flexible that the bicycle can be laid down while remaining attached to a trailer standing in an upright position. The bicycle trailer comprises a trailer frame having two rectangular members, each rectangular member having opposite end portions which are centrally and pivotally attached to the opposite end portions of the other rectangular member; and each rectangular member having a lower side portion extending generally horizontally along one lower side portion of the trailer and an upper side portion extending generally horizontally along an upper side portion of the trailer; a strap extending between the rectangular members to maintain the members in spaced relationship; a tongue member; a releasable hitch; a trailer bottom portion extending between the lower side portions of the rectangular frame members; and, wheels each rotatingly mounted to an opposite central portion of the lower side portion of the trailer frame.
