（1）Constitute：1. Frame: The frame is the main part of the entire vehicle, and its structural strength and stability directly affect the overall quality of the vehicle. According to market analysis, aluminum alloy is commonly used for the main body of the frame. Aluminum alloy is a quite suitable material for vehicle frames due to its high strength and light weight.

2. Front Frame: The interior of the front frame is used to house the battery and controller. The exterior connects to the front wheel and handlebars, interfaces with the rear frame, and includes the placement of the front headlight.

3. Rear Frame: As a key component of the vehicle, the rear frame must not only have a sturdy design, but also accommodate internal routing of power cables, brake lines, and other control wiring. Externally, it must connect to the rear wheel. Its design should also follow the principles of material conservation and weight reduction.

4. Wheelbase: This refers to the distance between the front and rear wheels. The wheelbase of modern electric scooters is typically around 80 cm. The wheelbase length affects the overall feel of the scooter's deck: a longer wheelbase provides a better riding experience, but may result in a slightly slower speed.

5. Deck: A usable skateboard deck is typically formed through compression molding. Some decks have a smooth layer made of special chemical substances on their bottom surface.

6. Wheels: Tire sizes are mostly in the range ofBetween 8 to 10 inches, generally speaking, the larger the scooter wheels, the faster the speed and the better the shock absorption. The front wheel primarily handles steering and is usually equipped with air tires that are wear-resistant and highly stable. The rear wheel mainly provides propulsion, has a more complex structure, and typically uses vacuum explosion-proof tires with hub motors, offering excellent wear resistance, safety, comfort, and stability.
