[0054] Furthermore, a rear seat support assembly 117 is provided on the rear mounting portion 115. The rear seat support assembly 117 includes a rear seat connecting bracket 1171, which is a basically U-shaped plate structure. It includes a first region 1171a and a second region 1171b. This is mainly because the rear seat cushion 142 is relatively large. Therefore, the first region 1171a is used to connect with the rear mounting portion 115, and the second region 1171b is suspended relative to the rear mounting portion 115. In this embodiment, the first region 171a refers to the two sides of the "U-shaped" structure of the rear connecting bracket 1171; the second region 1171b refers to the bottom edge of the "U-shaped" structure of the rear connecting bracket 1171.

[0055] Furthermore, a weight-reducing groove 1171c is formed on the first region 1171a of the rear seat connecting bracket 1171. In this embodiment, the weight-reducing groove 1171c is the middle part of the "U-shaped" structure. The opening of the weight-reducing groove 1171c is set towards the front of the electric two-wheeled vehicle 100, which can reduce the weight of the rear seat connecting bracket 1171 and facilitate its installation on the rear mounting part 115.

[0056] Furthermore, a hook 1172 is provided on the second region 1171b of the rear seat connecting bracket 1171. The hook 1172 is used for positioning and connecting with the rear seat cushion 142.

[0060] The seat bucket 121 includes a seat bucket body 1211, on which a long seat cushion connecting bracket 1212 is provided. The long seat cushion connecting bracket 1212 can be plate-shaped, and its shape matches the long seat cushion 143. When viewed along the length direction of the electric two-wheeled vehicle 100, the length of the long seat cushion connecting bracket 1212 is greater than the length of the seat bucket body 1211. This makes part of the long seat cushion connecting bracket 1212 located above the seat bucket body 1211, and part of it extends from the rear end of the seat bucket body 1211 to the rear end of the electric two-wheeled vehicle 100.

[0061] The long seat cushion connecting bracket 1212 can rotate relative to the seat bucket body 1211. For example, the pivot can be set at the front end of the seat bucket body 1211, so that the long seat cushion connecting bracket 1212 can rotate relative to the seat bucket body 1211 towards the front of the vehicle to open.

[0062] Furthermore, the side end of the seat bucket body 1211 in the seat bucket 121 is connected to the front mounting part 114, for example, the side end of the seat bucket body 1211 and the front mounting part 114 can be connected by fasteners; the rear part of the long seat cushion connecting bracket 1212 in the seat bucket 121 is connected to the rear mounting part 115, so that the seat bucket 121 can be mounted on the main frame 111 through the two mounting points of the front mounting part 114 and the rear mounting part 115.

[0063] Furthermore, considering that the position of the rear mounting part 115 is relatively lower than the position of the long seat cushion connecting bracket 1212, the end of the long seat cushion connecting bracket 1212 is connected to the rear mounting part 115 through the rear mounting part connecting bracket. Here, the rear mounting part connecting bracket has a boss-shaped structure and is set on the rear mounting part 115. In order to ensure that the long seat cushion 143 is set as horizontally as possible, the size of the rear mounting part connecting bracket can be determined according to the height of the long seat cushion 143.

[0064] This embodiment enables the installation of different types of seat cushions 14 through the front mounting part 114 and the rear mounting part 115 on the main frame 111 of the electric two-wheeler 100, thereby matching different types of electric two-wheelers 100 and different styles of vehicle appearance design, realizing the vehicle frame platformization, reducing frame design and development costs and shortening the verification cycle.
