The invention provides a pedal type bicycle which is driven by double legs in a forward, backward, upward and downward swing mode. The driving mode better conforms to the characteristics of human engineering, and a higher running speed can be achieved. The pedal type bicycle is mainly composed of the following basic structures, namely, a front frame with a bicycle head, and a front wheel; a front bicycle head and a rear wheel are connected through a frame; a support is arranged on the appropriate section of the frame; swing shafts of a left front swing rod and a right front swing rod are arranged on the support through bearings; a bevel gear is arranged at the other end of the swing shaft of each swing rod; the face-to-face bevel gears are meshed and driven through a partition bevel gear. The rear wheel and a drive shaft are coaxially arranged through a wheel axle. A drive and speed change mechanism and a one-way clutch are concentrated in the rear wheel. The extending left end and the extending right end of the drive shaft are connected with rear swing rods through swing shafts formed by one-way bearings. In a left movable pedal and a right movable pedal, each movable pedal is connected with the corresponding front swing rod and the corresponding back swing rod on the same side through bearings, and a user can conduct treading to ride the bicycle when the two legs are quite close to each other.
