The invention relates to the actuating technique of bicycles, in particular to a recumbent bicycle employing a method of rack actuation. The recumbent bike comprises a front wheel, a rear wheel, a frame for connecting the front wheel to the rear wheel, a faucet handle on the rear wheel, a recumbent saddle arranged on the frame and an actuating device for the front wheel, which is characterized inthat the front wheel actuating device employing a rack actuating mechanism can move linearly, wherein the rack actuating mechanism comprises a ratchet connected with a wheel shaft of the front wheel,a toothed rack bar engaged with the ratchet gear and a pedal connected with the toothed rack bar, the front wheel can rotate when the toothed rack bar moves forwards, then the front wheel rolls forwards while the toothed rack bar moves backwards, and the ratchet has little influence on the front wheel, thereby the front wheel can rotate normally. The recumbent bicycle has the advantages of energysaving in riding, fast forward speed and the like.
