A bicycle axle, including:
- a mandrel, defining an axial direction, including an axial rod, a head portion radially protruding from an end of the axial rod and an engaging portion radially protruding from the axial rod and being axially spaced apart from the head portion;
- a sleeve member, being rotatably sleeved around the head portion, including a flange radially and integrally extending inwardly, at least part of the flange being located between the head portion and the engaging portion and being abuttable against the head portion and the engaging portion in the axial direction;
- wherein the engaging portion includes at least one engaging projection, the at least part of the flange is interferable with the at least one engaging projection in the axial direction;
- wherein each of the at least one engaging projection includes an inclined guiding surface located at a side remote from the head portion;
- wherein an inner circumferential surface of the flange has a lip radially and inwardly protruding integrally therefrom, the lip is located between the head portion and the engaging portion and is interferable with the head portion and the engaging portion in the axial direction;
- wherein an inner circumferential surface of the lip and an outer circumferential surface of the axial rod define a first gap therebetween, and the inner circumferential surface of the flange and the outer circumferential surface of the axial rod define a second gap located at a side of the engaging portion axially opposite to the first gap.
