A double clamp clipless pedal includes a pedal body, a main shaft, and a clamp assembly. The pedal body has a first surface and a second surface. The clamp assembly is provided with a front clamp and a rear clamp rotatably disposed on two sides of the main shaft, such that the front clamp and the second clamp permanently rotate toward the main shaft for engaging a shoe cleat. The front clamp and the rear clamp are allowed to automatically swing together with the shoe cleat movement for maintaining the engagement. The front and rear clamps are able to resiliently and rotationally open, whereby the shoe cleat is easily clamped and disclamped by the front and rear clamps.
