Abstract: An easy-pedaling and labor-saving bicycle includes a frame, a front and a rear wheel set, a transmission set driving the rear wheel set, and a pedal device driving the transmission set. The pedal device includes a crank disposed on the frame, a link-up member driving a rear link-up plate to rotate, a link-up strip disposed between one end of the crank and the link-up member, a pedal unit disposed at the other end of the crank, and a straining member disposed between the frame and the link-up strip. Pedaling the pedal unit makes the crank set as an extension of a moment arm for increasing a force moment imparting to the transmission set. The crank swings downward easily to allow the other end thereof to pull the link-up strip, whereby the link-up member, the transmission set, and the rear wheel are driven to pedal easily, save labor and drive quickly.
