The utility model provides a folding type folding bicycle which comprises a bottom frame (6), a front frame (2), a rear frame (3), a left side frame (4) and a right side frame (5), when the folding bicycle is folded, the middle of the bottom frame (6) is pulled upwards to enable a front frame part (11) and a rear frame part (12) to be folded oppositely, a left matching structure (21) moves upwards from the lower end along a left guide structure (20), and a right matching structure (24) moves upwards from the lower end along a right guide structure (23); the front frame (2) and the rear frame (3) draw close to each other to link the parallelograms of the left side frame (4) and the right side frame (5) to draw close synchronously so as to lift the middle support, so that the front frame (2), the rear frame (3), the left side frame (4), the right side frame (5), the front frame part (11) and the rear frame part (12) draw close to each other and finally form a folded state, and the front frame part (11), the rear frame part (12) and the connecting seats can form a U-shaped storage space (16) with a downward opening; the volume can be reduced, and the capacity can be as large as possible.
