The invention provides a portable two-wheel folding bicycle which is mainly composed of a front wheel carrier, a bicycle frame, a folding handlebar, a seat, pedals, a rear wheel carrier, wheels and accessories. The portable two-wheel folding bicycle is characterized in that the front wheel carrier is formed by connecting two forked longitudinal beams to the rear portion of a front fork steering vertical pipe; the bicycle frame is formed by connecting a middle seat vertical pipe and plates through horizontal rods, wherein the plates are arranged front and back in parallel in the longitudinal direction; the front wheel carrier and the rear wheel carrier are hinged to the front end and the rear end of the bicycle frame, or slide in sliding grooves formed in the plates of the bicycle frame; longitudinal groove seats are fixed on the two sides of the front end of each plate; sliding blocks in beam pipes of the front wheel carrier longitudinally extend out and slide into the groove seats; radial grooves are formed in hinging shafts, and lateral pins in the grooves are pulled to the axis through springs; corresponding hinging pieces are provided with concave grooves; when rotating grooves coincide, the lateral pins are clamped into the concave grooves due to elastic force to be locked. When the components are folded, Z-like shapes are formed among the components; a box shape is formed by arranging the front wheel and the rear wheel on the two sides of the seat vertical pipe, clamping the front wheel and the rear wheel between the two plates of the bicycle frame, inserting a seat saddle pipe into the seat vertical pipe, hinging the pedals to a front wheel carrier beam and hinging the folding handlebar to a steering pipe of the front wheel carrier; the components are unfolded to become the bicycle which can be ridden by people; the portable two-wheel folding bicycle has the characteristics of being quick to fold and small in size, and can be carried when people take other vehicles and ridden for a short distance during transference.
