A folding bicycle, including the bicycle frame, the connecting pillar for front fork, the front fork of bicycle, the rear fork bracket of bicycle, the lock stem, the mounting stem of lock stem, and the return spring. According to the design in the present invention, the saddle is folded, the bicycle and the handlebar are retracted and folded and the lock stem is set in sequence. The lock stem is correspondingly clamped on the front fork to tightly fix the front fork and rear fork of the bicycle together using the elasticity of the spring, which could effectively solve the problem that the folding mechanism in the folding bicycle currently available on the market is complicated, the bicycle body after being folded is larger, and the front fork and rear fork of the bicycle body cannot be put together and fixed, resulting in be difficult to carry or transport. Meanwhile, after being folded, the front wheel and the rear wheel are on the same straight line. By adjusting the height of saddle, after the height of saddle is adjusted, the movement of bicycle can be pushed, so that the portability is better and the practicability is stronger, which is more suitable for large-scale popularization and application.
