The invention relates to an axial barehanded quick dismountable battery wheel. The axial barehanded quick dismountable battery wheel comprises a wheel axle, batteries, a wheel hub, a wheel and vehicle forks, wherein an axle section, from the right end to a middle-right part, of a right wheel axle is provided with an axial through hole and a lower axial groove, an axle section at the left end of the right wheel axle is provided with an axial axle connecting hole, an axle section at the right end of a left wheel axle is a small-diameter section with the diameter and length which are equal to those of the axle connecting hole, the small-diameter section is arranged in the axle connecting hole, a middle section of the wheel axle, formed in a manner that the right wheel axle is connected with the left wheel axle, is nested in a middle-hole battery pack, an axle section at the right side of the battery pack is fixedly nested in a bearing of a wheel hub disc, an axle section at the left side of the battery pack is movably nested in an axle sleeving slit tube, the right section of the axle sleeving slit tube is fixedly nested in a bearing of a wheel hub cover, the left section of the axle sleeving slit tube is nested in a quick release, the wheel is mounted at the outer edge of the wheel hub disc, the left side edge of the wheel hub disc is provided with an annular inner concave port, the right side edge of the wheel hub cover is provided with an inner convex port matched with the inner concave port, an axle section at the right of the bearing of the wheel hub disc is sequentially nested in an axle sleeving tube and fastened to a right vehicle fork from left to right, and an axle section at the left of axle sleeving slit tube is provided with a quick-released left vehicle fork or a screwed left vehicle fork. Thus, batteries can be dismounted from the axial direction in seconds in a barehanded manner, so that a vehicle can be miniaturized and folded.
