A bike trailer frame structure includes a rear frame and a base frame. The rear side of the base frame is mounted with left and right pivot bases, that have a fixing hole (fixing groove) respectively connected to the bottom side of the rear frame through a respective positioning element. Thereby, when the right positioning elements are released, the rear frame can pivot toward the base frame and fold, or can pivot in the direction opposite to the base frame, and then fix the positioning elements to the fixing holes or fixing grooves of the pivot bases to complete the unfolding action. Therefore, the invention simplifies the folding structure of the rear frame and the base frame in the front and rear directions. It has the practicality of streamlined components, uncomplicated manufacturing, simple and convenient assembly, and saving transportation space.
