The invention discloses an electronic rear shifting device and a manpower vehicle. The electronic rear shifting device is mounted on a frame and is in transmission connection with a speed change gear disc on the frame, and the electronic rear shifting device comprises a base fixedly mounted on the frame along a mounting axis, and two first pivot pins are arranged on the base; one side of the movable assembly is provided with two second pivot pins, the two second pivot pins and the two first pivot pins form parallel four-corner positions, and the other side of the movable assembly is pivoted with a chain guide piece which is in transmission connection with the speed change gear disc; one end of the outer connecting rod is pivoted to one first pivot pin, and the other end of the outer connecting rod is pivoted to one second pivot pin; one end of the driving assembly is pivoted to the other first pivot pin, the other end of the driving assembly is pivoted to the other second pivot pin, and the driving assembly is configured to be capable of rotating and driving around the axis of the first pivot pin; the included angle between the installation axis and the axis of the first pivot pin is 60-80 degrees. According to the electronic rear shifting device, the whole electronic rear shifting device is obliquely arranged relative to the vehicle frame, so that the device can avoid the vehicle frame during movement gear shifting.
