Abstract

See full text

A bicycle frame for bicycles with an upper cross bar is provided wherein the upper cross bar does not injure the rider as the rider straddles the cross bar after a stop. The bicycle frame also has an upper cross bar comprising an inner moiety slidably disposed within an outer moiety such that the first end of the inner moiety is outside the outer moiety. A spring is disposed within the upper cross bar to urge the second end of the inner moiety away from the outer moiety. The front end of the upper cross bar is hinged to the head post and the rear end of the upper cross bar is slidably attached to the seat post. A second spring is attached to the frame and adapted to urge the upper cross bar upwards. The springs are chosen so that no discomfort is caused to a rider of a bicycle having the bicycle frame when the rider dismounts the bicycle, straddles the upper cross bar and, by the weight of the rider's body, pivots the rear end of the upper cross bar downward until both feet of the rider touch the ground.
