A bicycle trailer includes a looped carrier frame and two pairs of vertical sleeves which extend upward from front and rear end portions of the carrier frame. The sleeves have surrounding walls of U-shaped horizontal cross-section, thereby forming vertical openings in the surrounding walls. Each surrounding wall is provided with two opposing horizontally aligned holes. A plurality of horizontal pivot members extend through the aligned holes substantially in parallel with a line that extends from the front end portion to the rear end portion of the carrier frame. Each of a pair of curved support rods has two end portions which are inserted respectively into one of the sleeves of the front end portion and one of the sleeves of the rear end portion. The end portions of the support rods have horizontally extending tubular members to be sleeved rotatably and respectively on the pivot members so as to turn the support rods by passage through the openings in the surrounding walls, thereby permitting the support rods to turn upward to an upright position or downward to a storage position.
