摘要： The invention discloses a novel rapidly foldable electric vehicle comprising a main beam, a rear wheel, a cross beam, a bracket and a forward/backward movable saddle, wherein a pin is arranged at a junction between a lower end of the bracket and the main beam, a supporting post is arranged at the lower end of the bracket, the bracket and the supporting post are rotatably arranged about the pin, an included angle of less than 180° is formed between the supporting post and the bracket, and a towing wheel is arranged at a lower end of the supporting post. When the vehicle is folded, the saddle slides forward from a rear part of the cross beam and drives the bracket and the supporting post to rotate counterclockwise about the pin, the towing wheel moves downward and backward and gradually touches the ground, and after the towing wheel touches the ground, the rear wheel leaves the ground and the saddle moves to a front part of the cross beam to complete the folding action, thus the vehicle is in a towed or flat state. When the vehicle is towed, the towing wheel is positioned at a middle-rear part of a vehicle body, and when a human body stands upright, the vehicle body tilts, its center of gravity naturally shifts backward, the vehicle body has less pressure on the human body and towing is performed with less effort. When the vehicle is folded, the saddle moves forward without moving backward and the rear space of the vehicle body can be saved. When the vehicle is folded and laid flat, the towing wheel touches the ground and the vehicle body does not tip over easily.
