A bicycle hub shaft includes a first shaft section made of a first material and inserted into a sprocket seat; and a second shaft section made of a second material. The strength of the first material is stronger than that of the second material. The first shaft section has one end connected to one end of the second shaft section. The bicycle hub shaft is formed by the first and second shaft sections, instead of being integrally formed. Besides, the strength of the first shaft section is stronger than the second shaft section, so that the first shaft section inserted in the sprocket seat has a higher structural strength, thus improving the strength of the bicycle hub shaft and the load capacity of the sprocket seat as well.
