The invention discloses a bicycle handle frame folding mechanism which is provided with a handle frame rod and is characterized in that the handle frame rod is arranged on a swing seat and can drive the swing seat to rotate, the swing seat is hinged to a transmission seat and can drive the transmission seat to rotate, and the transmission seat is connected with a front wheel frame. A movable transmission sleeve is arranged on the handle frame rod, a first limiting piece is arranged on the handle frame rod, a first annular groove capable of containing the first limiting piece is formed in the transmission sleeve, the transmission sleeve is further provided with a first guide groove which is communicated with the first annular groove and can allow the first limiting piece to penetrate through, and a cavity is formed in the handle frame rod. A cavity is formed in the transmission sleeve, a movable locking sleeve is arranged in the cavity, a second limiting piece is arranged on the locking sleeve, a second guide groove allowing the second limiting piece to penetrate through is formed in the handle rod frame, a second annular groove capable of containing the second limiting piece is formed in the transmission sleeve, and the positioning piece is fixed to the transmission base. And the positioning piece can be matched with the locking sleeve to limit the swinging of the locking sleeve and the handle frame rod. The handle frame of the bicycle is simple in structure and reasonable in design, up-down swing folding of the handle frame of the bicycle can be conveniently achieved, and the bicycle can be stored and transported with a smaller size.
