A trailing rod assembly is provided to couple front ends of two lower beams of a baby carrier to a bicycle chain stay. The trailing rod assembly includes a substantially S-shape rod, a front coupler mounted to a front end of the rod, a rear coupler mounted to a rear end of the rod, a wheel seat mounted to a mediate portion of the rod, and a beam-fixing seat mounted between the wheel seat and the rear coupler. The front coupler includes a main plate, a movable plate, a fixing knob, and a flexible tube, wherein the chain stay is securely held between the main plate and the movable plate. The wheel seat includes an L-shape slot for retaining an axle of a front wheel of the baby carrier. The rear coupler includes a lower plate, an upper plate, and two fixing knobs, wherein the rear end of the rod is soldered to a surface of a mediate groove of the lower plate.
