A vehicle wheel includes a wheel body having an elongated guiding slot
radially extended from a center of the wheel body; and an axle
centrifugal adjusting arrangement, which includes a sliding member
slidably mounted along the guiding slot for mounting the wheel body to
the wheel axle; and a gear adjustment device including a first gear unit
mounted at the guiding slot of the wheel body, and a second gear unit
mounted at the sliding member to substantially engage with the first gear
unit so as to selectively adjust the sliding member to slide along the
guiding slot.
