The bicycle front fork comprises a front-fork vertical tube, and two front-fork branch tubes connected with the front-fork vertical tube. The bicycle front fork is characterized by further comprising a support plate, rotating support rods, supporting rollers and lock plates, wherein the support plate is fixed at the lower parts of the front-fork branch tubes; the rotary support rods are mounted on the support plate through a rotating shaft; a lock hole is formed in the supporting plate, on one side of the rotating shaft; a lock pin is mounted in the lock hole in an inserted manner; each supporting roller is mounted at the free end of the rotating support rod; each lock plate is arranged at the fixed end of the rotating support rod; an expansion hole which is opposite to the lock hole and allows the lock pin to penetrate through, and a reclaiming hole which is opposite to the lock hole and allows the lock pin to penetrate through are formed in each lock plate. Through the adoption of the bicycle front fork disclosed by the invention, an accident that because the front wheel of a bicycle is suddenly braked, the bicycle overturns forwards can be effectively avoided, so that the safety performance of the bicycle is improved.
