An electric vehicle with partitionable frame includes a chassis assembly, a head tube, a front wheel, left and right rear wheels, and a seat. The front wheel is assembled at the base of the head tube through a fork, and the bottom part of the head tube is pivoted and located in the shaft sleeve lying on the front end of the oblique bracket. The seat is assembled on a vertical seat tube lying on the rear section of the chassis assembly. The chassis assembly includes front and rear assemblies that are partitionable. Connecting ends of the two assemblies are set with at least two groups of opposite jacks and opposite punch pins, which appear to be horizontally opposite and mutually embedded and mounted when assemblies are aligned. At least one set of positioning pieces controls the fixed or partitioned state of the two assemblies after they are aligned.
