The utility model provides an electric vehicle frame and a unique folding method, wherein the electric vehicle frame with a large-capacity battery concealed in a circular arc convex vehicle pipe is combined with a rear vehicle frame to be in a simple, fashionable and special shape, can avoid shock and can be folded, and can also be manufactured into a common folding bicycle. When an electric vehicle is mounted, the electric vehicle can be used only by arranging the battery (16) into an arc-shaped battery box (1). When the electric vehicle frame is folded, a mortise lock (10) on a spring is pulled out, then a handlebar (4) is lifted upwards by means of gripping, and a rear wheel (8) with downward gravity is folded together with a front wheel (3), so that the electric vehicle frame is easy in folding.
