Abstract A safety device is presented to prevent a rider from tipping a bicycle over backward and injuring himself. The device is simple to construct and easy to attach to the bicycle and comprises a couple of generally parallel struts which are pivotally attached to an extension of the axle of the rear wheel of the bicycle and provides a roller at the rear end of the struts and projections at the front end of the struts adapted to overlie a portion of the main frame of the bicycle so that when the bicycle is tilted by lifting the front wheel upwardly, the roller engages the ground and the forward projections hit the frame of the bicycle to arrest the tilting of the bicycle before the rider goes over backwards.

A safety device for attachment to a bicycle having a main frame and front and rear wheels to prevent the same being tipped over backward by its rider, said frame having two linear rigid horizontal frame members extending from opposite sides of a pedal sprocket to opposite sides of a rear wheel axle, comprising a pair of rigid struts generally parallel, a rotatable roller connected between said struts at one end adapted to engage the ground when the bicycle is tipped backward, a parallel projection means rigid with and extending from near the opposite ends of said struts with L-shape ends in position to overlie said horizontal frame members respectively, said struts being pivoted to said frame at a point along said projection means on the extended axle of said rear wheel, and a plurality of pairs of spaced registering openings through said projection means in position for varying said attachment to said bicycle frame.
