A vertically placed, lift generating wing is affixed adjacent to, and forward of the steering head of a bicycle, or pedal cycle. This results in a conversion into a wind powered, sail propelled, vehicle for use as recreational enjoyment, as well as a practical mode of transportation. The resulting sail bike utilizes a mast attachment bracket (8) to support a lift generating wing which is generally comprised of; sail (1), sail luff pocket (2), mast (3), boom (5), sail trim rigging (10), battens (14) and other rigging and fasteners. The sail bike can properly perform all of the functions characteristic of a true sailing vehicle, including; sailing throughout course headings of 270 degrees relative to the wind's direction, beating, reaching, and running, and it will also permit safe and immediate execution of all maneuvers common to sailing vessels, including tacking, jibing and continuous sail trimming. The advantage of the sail bike is in the simplicity of the design, the ease of set up, and in its highly efficient operation as a sailing vehicle.
