A hub for a bicycle comprises a flange formed at either side thereof, in the flanges are annularly formed a plurality of apertures through which a plurality of spokes are inserted and connected to a rim. On an axial surface of the hub are formed a plurality of locking holes that are located between the flanges of the hub for securing an end of the spokes, another end of the respective spokes is secured to the rim, so that the spokes between the hub and the rim are tensioned evenly and properly and can be prevented from inappropriate deformation, and accordingly the bicycle can run more safely.
