As shown in fig. 2 to 7, the frame 11 includes a main frame 111 for supporting the entire vehicle structure and an auxiliary frame 112, and the auxiliary frame 112 is at least partially disposed behind the main frame 111 and is detachably connected to the main frame 111. The main frame 111 includes a first side pipe 1111, a second side pipe 1112, a head pipe 1113, a third side pipe 1114 and a fourth side pipe 1115, wherein the first side pipe 1111 and the second side pipe 1112 are disposed on one side of the electric two-wheeled vehicle 100, and the third side pipe 1114 and the fourth side pipe 1115 are disposed on the other side of the electric two-wheeled vehicle 100. A longitudinal center plane 101 perpendicular to the width direction of the electric motorcycle 100 and passing through the width center of the electric motorcycle 100 is defined, and since the main frame 111 of the electric motorcycle 100 is disposed substantially symmetrically with respect to the longitudinal center plane 101, only the first side pipe 1111 and the second side pipe 1112 on one side will be described below for the symmetrical structure.

As an alternative embodiment, the first side pipe 1111 and the second side pipe 1112 are disposed substantially along the longitudinal direction of the electric bicycle 100, and the first side pipe 1111 is disposed above the second side pipe 1112. The main frame 111 further includes a head pipe 1113, and the first side pipe 1111 and the second side pipe 1112 are fixedly connected to the head pipe 1113. The rear end of the first side pipe 1111 is fixedly connected to the second side pipe 1112. A receiving gap 1118 is formed between the first side tube 1111 and the second side tube 1112. The frame 11 further includes a pedal bracket 113, and the pedal bracket 113 is distributed along the width direction of the electric bicycle 100 and is at least partially disposed in the accommodation gap 1118. The first side pipe 1111, the second side pipe 1112, the head pipe 1113, the third side pipe 1114, and the fourth side pipe 1115 may be provided as any one of round pipes, rectangular pipes, or oval pipes. Under this kind of setting, first side pipe 1111 and second side pipe 1112 constitute upper and lower double-deck side pipe, and third side pipe 1114 and fourth side pipe 1115 constitute upper and lower double-deck side pipe, have strengthened the bulk strength of frame 11, still provide the installation position for pedal support 113, and frame 11 arranges compacter, and space utilization is higher.

As an alternative embodiment, the first side tube 1111 includes a straight section 1111a and an extension section 1111b extending substantially upward, and the front end of the second side tube 1112 is connected to the extension section 1111 b. The second side pipe 1112 includes a horizontal section 1112a and an extension section 1112b extending substantially upward, the front end of the first side pipe 1111 is connected to the head pipe 1113, and the rear end of the first side pipe 1111 is connected to the extension section 1112 a. A plurality of reinforcing members 1117 are further arranged between the first side tube 1111 and the second side tube 1112, and the reinforcing members 1117 are connected between the first side tube 1111 and the second side tube 1112, so that the strength of the double-layer side tube formed by the first side tube 1111 and the second side tube 1112 is enhanced, and the installation position is provided for the wire harness on the electric two-wheel vehicle 100. The flat section 1111a and the second side tube 1112 form a substantially triangular structure around the rear end, enhancing the overall strength of the rear end of the frame 11.

The upper end surface of the front battery mounting plate 114 is substantially parallel to the reference plane 102. The distance H from the highest point of the connection of the first side pipe 1111 to the extension 1111b to the reference plane 102 in the height direction of the electric two-wheeled vehicle 100 affects both the installation space of the power unit 16 and the foot position of the driver. When the distance H from the highest point of the connection of the first side pipe 1111 and the extension 1111b to the reference plane 102 in the height direction of the electric two-wheeled vehicle 100 is greater than 100mm, the middle and rear sections of the first side pipe 1111 are higher, and since the front battery mounting plate 114 is disposed on the first side pipe 1111, the position of the front battery mounting plate 114 is higher, the mounting space of the power assembly 16 is reduced, and the arrangement of the power assembly 16 is not facilitated. When the distance H from the highest point of the connection of the first side pipe 1111 and the extension section 1111b to the reference plane 102 along the height direction of the electric two-wheeled vehicle 100 is less than 80mm, the pedal position of the electric two-wheeled vehicle 100 is low, which does not meet the riding requirement of the driver; and because the vehicle body panel 15 is arranged outside the first side pipe 1111 and the second side pipe 1112, the vehicle body panel 15 is positioned at a lower position and is easily damaged by road surface foreign matters. As an alternative embodiment, the distance H from the highest point at which the first side pipe 1111 connects with the extension 1111b to the reference plane 102 in the height direction of the electric two-wheeled vehicle 100 may also be 84mm or more and 96mm or less; as an alternative embodiment, the distance H from the highest point at which the first side pipe 1111 connects to the extension 1111b to the reference plane 102 in the height direction of the electric two-wheeled vehicle 100 may be 88mm or more and 92mm or less. Through the above arrangement, not only the strength of the frame 11 is ensured, but also the installation space requirements of the front battery installation plate 114 and the pedal bracket 113 are satisfied.
