Abstract
Abstract A pivoting guard arm device is detachably mounted at one side of a two-wheel vehicle such as a bicycle. Mounting means secured to the bicycle holds the guard arm in a normally retracted position at one side of the bicycle. From its retracted position, the arm may be swung outwardly into laterally projecting relationship to that side of the bicycle exposed to passing traffic when operated on a highway or other thoroughfare. A reflector or other desired signalling means located on the outer end of the guard arm aids in indicating the presence of the bicycle to vehicles approaching from the rear and especially serves to indicate proximity of vehicles passing the bicycle so that a safe passing clearance may be more readily maintained. The mounting means may be attached at some desirable point on the bicycle body, and preferably may be engaged about the rear bicycle wheel shaft. Included in the mounting means is a bracket holder and a bracket component for adjustably supporting the arm in its several positions of adjustment.
