As shown in fig. 2 and 3, the powertrain 16 includes a battery 161 and a motor controller 162, both of which are disposed below the cushion assembly 14, and the battery 161 and the motor controller 162 are at least partially disposed in an accommodation space formed between the cushion assembly 14 and the main frame 111. The motor controller 162 is disposed at the rear of the battery 161, and the distance between the motor controller 162 and the battery 161 is less than a preset value. On a transverse plane perpendicular to the longitudinal direction of the electric two-wheeled vehicle 100, the projection of the motor controller 162 on the transverse plane along the longitudinal direction of the electric two-wheeled vehicle 100 coincides with the projection of the battery 161 on the transverse plane along the longitudinal direction of the electric two-wheeled vehicle 100. The motor controller 162 is disposed on the support cross tube 1113. The support cross tube 1113 not only strengthens the main frame 111, but also provides a mounting frame for the motor controller 162.

The connection lines between the battery mounting frame 1118 and the mounting positions of the first support vertical pipe 1112a, the second support vertical pipe 1112b and the third support vertical pipe 1112c are formed in a triangle shape, so that the main frame 111 is more stable, and the battery 161 is placed on the battery mounting frame 1118 and limited by the first support vertical pipe 1112a, the second support vertical pipe 1112b and the third support vertical pipe 1112c, so that the mounting is more stable.

As an alternative embodiment, the motor controller 162 extends substantially in a preset plane, and an included angle α formed by intersecting the preset plane and the reference plane is greater than or equal to 9 ° and less than or equal to 15 °, and the motor controller 162 is obliquely disposed within the angle range, so that the motor controller 162 is more convenient to detach and maintain. The bottom surface of the motor controller 162 is inclined with respect to the reference plane, and after the electric two-wheeled vehicle 100 is waded, dust, water stain or other pollutants remained on the motor controller 162 can flow to the ground along the bottom surface of the motor controller 162, so that the accumulation of pollutants on the bottom surface of the motor controller 162 can be reduced. In addition, this arrangement is more convenient when assembling or inspecting the motor controller 162. When α is larger than this range, the line of sight is required to be squatted down or bent over for viewing the side mounting point during assembly, which is inconvenient. When α is smaller than this range, it is difficult to reduce the accumulation of contaminants on the bottom surface of the motor controller 162. As an alternative embodiment, the included angle α formed by the intersection of the preset plane and the reference plane may be greater than or equal to 10 ° and less than or equal to 14 °; as an alternative embodiment, the included angle α formed by the intersection of the preset plane and the reference plane may be greater than or equal to 12 ° and less than or equal to 13 °. The distance from the lowermost end of the motor controller 162 to the connection line of the front wheel 131 touchdown point and the rear wheel 132 touchdown point is H, i.e., the ground clearance of the lowermost end of the motor controller 162 when the driver is in the upright driving state. H is set to 540mm or more and 550mm or less. H is less than the above range motor controller 162 with the risk of water ingress; when H is greater than the above range, it is difficult to simultaneously satisfy the reinforcement of the vehicle frame 11 and the installation of the motor controller 162 by the support cross tube 1113, and the three-phase line increases with the increase of H, which increases the cost.
