The invention relates to a multi-functional pneumatic bicycle. The multi-functional pneumatic bicycle comprises a front wheel, a rear wheel and a unitized frame, wherein a cylinder and a control circuit are mounted on a front frame; a pneumatic motor is fixed on the side surface of a rear frame of the bicycle; a gear is mounted in a key slot of an output shaft of the pneumatic motor; a flywheel of the bicycle is mounted with a chain wheel; the gear is engaged with the chain wheel; blades are mounted between two spokes of the rear wheel; a rear wheel airbag is mounted on one side below a saddle; the lower part of the front wheel is clamped into a front wheel airbag; a push rod is mounted in a cylinder mounted on a front fork of the bicycle; the push rod is connected with a sleigh board; small crawler wheels are arranged at one ends of straight connecting rods; the straight connecting rods are connected with a curved connecting rod and a big crawler wheel; and the rear wheel, the big crawler wheel and the small crawler wheel are integrally connected with each other through a crawler belt. According to the multi-functional pneumatic bicycle provided by the invention, the multi-functional pneumatic bicycle is driven to move ahead by using compressed air and manpower as power; and the bicycle has dry land, snowfield and water walking functions. During walking on the dry land, the airbags and the sleigh board are closed up; during walking on the water, the airbags are used for supporting and the blade is used as paddles; and during walking on the snowfield, the sleigh board is driven by the cylinder to extend out downwards so as to eject up the front wheel, and the rear wheel is converted into the crawler wheels to run forwards. The multi-functional pneumatic bicycle provided by the invention is convenient and fast to switch.
