The present invention relates to a cardan joint steering titanium alloy hand and foot cooperatively operated bicycle capable of being ridden with one leg, which comprises a bicycle front wheel (10), a front wheel fork frame (11), a bicycle rear wheel (20), a frame body (30), a seat cushion assembly (50), a steering handlebar (70), paired chain wheels (80) and a rear wheel fork frame (90). The upper end of a front fork rotating shaft (13) and the lower end of an assisting stem (76) are connected through a cardan joint component (77), symmetric ratchet wheels (21) are provided on the two sides of the bicycle rear wheel (20), the paired chain wheels (80) are fixed to the two sides of a frame middle shaft (88), pedal shaft pins (84) are symmetrically provided on the outer sides of the paired chain wheels (80), and the paired chain wheels (80) and the symmetric ratchet wheels (21) are connected through symmetric chains (23). By additionally providing the cardan joint component (77), the assisting sliding sleeve (60), the assisting swinging rod (46) and the assisting connecting rod (43), the present invention realizes the effect that the two hands participate in acting; by additionally providing the seat transverse swinging rod (45) and the pull rod swinging fork (42), the limit that the positions of two pedals of the conventional bicycle must have a difference of 180 degrees is overcome, the two feet do not need to apply force alternately, and the bicycle can be ridden with one leg.
