Abstract: A wheel activated bicycle reflector attachment is rotated with and by the rotation of the bicycle wheel, reflecting a rotating or flashing pattern of light to oncoming traffic. The apparatus is adjustable to various size bicycles by means of a telecopic shaft and a pivoted bracket. A drive wheel, supported by the bracket, is rotated with and by rotation of the rear bicycle wheel and thus rotates reflectors connected to the drive wheel. The drive wheel axis of rotation is located rearwardly of the rear wheel axis of rotation to insure constant, positive engagement with the rear bicycle wheel.

Abstract: This invention relates to operator propelled water skis comprising a pair of elongated float-type ski members with suitable operator foot supports therein mounted in a thwart-type frame having outrigger floats attached thereto. A pair of ski pole floats are similarly positioned on the frame and are slidable relative thereto through movement of ski poles coupled to the floats to increase stability of the water skis to the operator and provide a means for propelling the skis. The ski members and ski pole floats have surfaces thereon which increase the resistance of movement of the floats and ski members in one direction of the skis and reduce resistance in the opposite direction of movement to aid in movement of the skis.
