Abstract
A wheeled vehicle includes a main frame, a drive axle rotatably mounted on the main frame, a chainwheel secured on the drive axle, an eccentric shaft secured on the drive axle, a support post mounted on the main frame, a rocking arm pivotally mounted on the support post, and a linking member having an upper end pivotally connected with the rocking arm to move with the rocking arm and a lower end pivotally connected with the eccentric shaft to move the eccentric shaft. The rocking arm has two opposite sides each provided with a pedal. Thus, the wheeled vehicle is driven to move forward by stepping the pedals of the rocking arm upward and downward in a reciprocal manner to provide a different pedalling manner.
