Abstract: A cantilevered article carrier assembly for attachment to the underside of the seat of a cycle, particularly a bicycle. A fabric bag is secured to one end of a support arm. A bracket is mounted to the underside of the bicycle seat, and the support arm projects through a slot in the bracket so that the other, free end thereof rests in engagement with the underside of the bicycle seat. A Velcro strap is provided on the bag to secure the bag to the bicycle seat support to tension the support arm about the bracket and to prevent the support arm from sliding out of the bracket. The bag includes a plastic insert which is folded about a perforated hinge into the desired shape to maintain the shape of the bag. The bag may be quickly removed from the bicycle by release of the Velcro strap.
