A bicycle trailer includes a frame with front and rear pivot seats, and a sunshade support provided with a foldable unit consisting of a vertical lower rod, a vertical upper rod and a curved rod. The lower rod has a bottom end connected pivotally to the rear seat and an upper end connected pivotally to the upper rod. The curved rod has a front end connected pivotally to the front seat and a rear end connected pivotally to a top end of the upper rod. A bracing element is mounted movably on the lower rod and capable of bracing the upper and lower rods together such that the upper and lower rods are immobilized to each other in a parallel manner. When depressed and pushed frontwardly of the frame, the bracing element permits folding action of the lower rod onto the frame, the upper rod onto the lower rod, and the curved rod onto the upper rod.
