A collapsible electric vehicle includes a front vehicle member, a vehicle frame pivotally coupled to the front vehicle member, a seat disposed at the vehicle frame, a power supply, a set of wheels disposed at the front vehicle member and the vehicle frame respectively, and a drive motor eclectically connected to the power supply. The drive motor is connected to at least one of the wheels to drive the wheel to rotate. The collapsible electric vehicle has an expanded state and a collapsed state. In the expanded state, a first supporting frame is expanded and maintained upright to support the seat to be at a suitable position while the front vehicle member is expanded to be positioned apart from the vehicle frame. In the collapsed state, the first supporting frame is collapsed to a main frame, and the front vehicle member is collapsed to the first supporting frame.

A folding vehicle is adjustable between an unfolded position and a folded position. In the unfolded position, the wheels of the vehicle are in a leading and trailing relationship. In the folded position, the components of the folding vehicle have a minimal footprint allowing for compact storage. In the folded position, the wheels may be in a side-by-side relationship with the majority of the vehicle components positioned between the wheels.

A light folding scooter having a bottom plate, and two sides of the bottom plate respectively provided with a lifting handle at a center of gravity of the sides of the scooter after the scooter is folded, and a scooter head and scooter tail of the bottom plate provided with a scooter head lifting handle and a scooter tail groove matched with the scooter head lifting handle for carrying the scooter, wherein the location of the two lifting handles on the sides of the bottom plate at the center of gravity of the scooter after the scooter is folded, allows lifting of the scooter using the two bottom plate lifting handles after being folded by hand can keep balance of a scooter body, which is convenient for carrying the scooter after being folded. When two people lift the scooter, one can locate at the scooter head position to hold the scooter head lifting handle and the other can locate at the scooter tail position to hold the scooter tail groove, so that the scooter can be easily carried. After the product is folded, the occupied space of the scooter body is greatly reduced, and the scooter is convenient to be accommodated on a transportation tool.
