A collapsible electric vehicle, comprising: a front vehicle member; a vehicle frame, wherein the front vehicle member is pivotally coupled to the vehicle frame; a seat, wherein the seat is supported by the vehicle frame; a power supply; a plurality of wheels provided at the front vehicle member and the vehicle frame respectively; and a driving mechanism, wherein the power supply is electrically connected to the driving mechanism for providing power to the driving mechanism, wherein the driving mechanism is operatively connected to at least one of the wheels to drive the said at least one wheel to rotate, wherein the vehicle frame comprises a main frame and a first supporting frame, wherein the first supporting frame is coupled at the main frame to move the collapsible electric vehicle between an expanded state and a collapsed state, wherein when the collapsible electric vehicle is in the expanded state, the first supporting frame of the vehicle frame is unfolded and retained at an upright manner while the front vehicle member is unfolded and moved away from the vehicle frame, wherein when the collapsible electric vehicle is in the collapsed state, the first supporting frame of the vehicle frame is folded on the main frame while the front vehicle member is folded on the first supporting frame; the collapsible electric vehicle further comprises a vehicle frame lock which comprises a first positioning member and a second positioning member, wherein the first supporting frame has a lower end portion and an upper end portion, wherein the upper end portion of the first supporting frame is pivotally coupled at the lower end portion thereof, wherein the first positioning member of the vehicle frame lock is coupled at the upper end portion of the first supporting frame, wherein the second positioning member is coupled at the lower end portion of the first supporting frame, wherein the first and second positioning members (81, 82) are engaged with each other when the first supporting frame is unfolded and are disengaged with each other when the first supporting frame is folded; characterized in that: the first positioning member of the vehicle frame lock has a pivot portion pivotally coupled at the upper end portion of the first supporting frame and a limiting portion extended from the pivot portion, wherein the second positioning member is movably coupled at the lower end portion of the first supporting frame in a reciprocating manner, wherein the second positioning member has a limiting end, wherein the limiting portion of the first positioning member and the limiting end of the second positioning member are arranged to be engaged with each other. a front vehicle member; a vehicle frame, wherein the front vehicle member is pivotally coupled to the vehicle frame; a seat, wherein the seat is supported by the vehicle frame; a power supply; a plurality of wheels provided at the front vehicle member and the vehicle frame respectively;
