Abstract: A luggage carrier for a three-wheel motorcycle is disclosed which forms a portion of a modification of the motorcycle, which is of a type generally known as an ATC, all-terrain cycle. The luggage carrier provides a generally rectangular flat-bed area and a pair of fenders, suspended over the rear wheel area of the cycle. A supporting frame of the flat-bed includes a forward extension to overlie the normal seat position of the cycle. The seat is unlatched from its normal position and is fixed atop the forward extension, after a pair of latch brackets have been removed from the bottom of the seat and remounted to a bottom portion of the forward extension in a compatible relation to a mounting and latch means conventionally provided in the seat mounting area of the cycle.
