A multi-speed hub gear includes an axle, a planetary gear set, a clutch, a transmission member, a guide wheel, a compressed clutch spring, a shift mechanism and a torsional spring. While in switching a low gear to a high gear, the shift mechanism transforms a rotational motion into a linear motion for twisting the torsional spring. The compressed clutch spring pushes the clutch to displace from the transmission member toward the planetary gear set. While in switching the high gear to the low gear, the torsional spring drives the shift mechanism to transform the rotational motion into the linear motion, such that the clutch can displace from the planetary gear set toward the transmission member, and compress the compressed clutch spring.
