The invention provides a bicycle chain guard assembly. The bicycle chain guard assembly comprises a guard body, a front installation portion and a rear installation portion, wherein the front installation portion and the rear installation portion are fixedly connected to a bicycle frame on the inner side of a chain; multiple locking lugs are arranged on the inner side face of the guard body; locking grooves allowing the locking lugs to be inserted are formed in the outer side faces of the front installation portion and the rear installation portion; the front installation portion and the rear installation portion are provided with locking holes; the locking holes perpendicularly penetrate through the locking grooves; locking pins are installed in the locking holes and sleeved with springs. When the bicycle chain guard assembly is in a mounted state, the locking lugs are inserted into the locking grooves, and the springs provide pressure to fasten the locking lugs between the locking pins and the groove walls of the locking grooves; when the bicycle chain guard assembly is in a dismounted state, the locking pins are pulled out by overcoming the resistance of the springs, and the locking lugs disengage from the locking grooves. Through cooperation of the locking lugs, the locking grooves and the locking pins, positioning and mounting of the guard body are achieved, an existing screw screwing fixation mode is replaced, the same fastening effect with screw fastening is achieved through multi-point fixation, dismounting is convenient, and a large enough operation space is provided for maintenance of the chain.
