This invention relates to a driving technology of wheel assembly, especially a driving method of wheel assembly and a bike driven by the method. The wheel assembly consists of a driving wheel equipped with a ratchet wheel. The driving wheel is characterized in that a rack of rectilinear motion drives the ratchet wheel, which further drives the wheel assembly. The driving method above is adopted for the driving wheel of the bike. With the invention method and structure above, in the wheel assembly driven by the rack of rectilinear motion, human's leg force can be completely converted to a moment driving the wheel assembly forward. The mechanical efficiency of the wheel assembly is higher than that of the conventional wheel assembly driven by the pedal and the chain wheel Therefore, the bike driven by the rack of rectilinear motion is labor saving and of quick movement, good entertainment and fitness effect.
