The invention discloses an anti-collision bicycle handlebar. The anti-collision bicycle handlebar is characterized by being composed of an inner joint (1) and outer joints (2) which are rotationally connected with the two ends of the inner joint (1) respectively, the rotational joints are further provided with anti-rotation pins (4), and potential energy pin starting mechanisms used for starting the anti-rotation pins (4) are arranged between the outer ends of the outer joints (2) and the anti-rotation pins (4). The potential energy pin starting mechanisms (5) comprise impact starting mechanisms, bounce transmission mechanisms and pin starting mechanisms. The anti-collision bicycle handlebar has the advantages that the energy unloading of the impact, from the back, on the bicycle handlebar is achieved, capsizing of a bicycle and a person after the impact is avoided, and the riding safety is guaranteed.
