[0023] As Figure 1 shown, an electric motorcycle 100 includes a frame 11, a body covering 12, a wheel assembly 13, a suspension assembly 14, a saddle assembly 15, and a lighting assembly 16. To clearly illustrate the technical solution of this application, the front side, rear side, left side, right side, upper side, and lower side as shown in Figure 1 are also defined.

The lighting assembly 16 is partially installed on the frame 11, and the lighting assembly 16 is used for providing lighting and warning functions.

[0024] As Figures 2 to 4As shown, as an implementation, the electric motorcycle 100 further includes a control system 18, a cooling assembly 19, an air intake assembly 24, and a power assembly 20. The power assembly 20 includes a motor 201, and the operation of the motor 201 can drive the rear wheel 132 to rotate, that is, drive the electric motorcycle 100 to travel. The cooling assembly 19 includes a radiator 191 and a water pump 192, and is used to cool the electric motorcycle 100. The control system 18 includes a motor controller 181, and the motor controller 181 can receive commands and issue commands to control the motor 201. The air intake assembly 24 is disposed on the lower side of the electric motorcycle 100. The air intake assembly 24 is connected to the frame 11 and the body cover 12. The air intake assembly 24 extends substantially along the front-rear direction of the electric motorcycle 100 and is used to cool the radiator 191, the motor controller 181, the water pump 192, and the motor 201. The air intake assembly 24 substantially wraps the lower side of the electric motorcycle 100, and the air intake assembly 24 forms an air intake duct 241. The air intake duct 241 extends substantially along the front-rear direction of the electric motorcycle 100, facilitating the cooling of the radiator 191, the motor controller 181, the water pump 192, and the motor 201 in the form of air cooling, which is beneficial to improving the heat dissipation effect of the electric motorcycle 100 and thus improving the service life of the electric motorcycle 100. Among them, the air intake duct 241 refers to the flow path through which air enters and exits the air intake assembly 24 during the driving process of the electric motorcycle 100.

[0025] As Figures 2 to 4As shown in the figure, specifically, the air intake assembly 24 includes an air inlet 242, a second air outlet 243, and a first air outlet 244. Along the front-rear direction of the electric motorcycle 100, the air inlet 242 is arranged on the front side of the body cover 12 and communicated with the air intake duct 241, and is used to allow air to enter the air intake assembly 24 during the running of the electric motorcycle 100, so as to cool the radiator 191, the motor controller 181, the water pump 192, and the motor 201 in the form of air cooling, which is beneficial to improving the heat dissipation effect of the electric motorcycle 100, and thus improving the service life of the electric motorcycle 100. Along the front-rear direction of the electric motorcycle 100, the first air outlet 244 is arranged near the motor 201 and is used to discharge air from the air intake assembly 24. Along the front-rear direction and the up-down direction of the electric motorcycle 100, the second air outlet 243 is located between the air inlet 242 and the first air outlet 244, that is, the second air outlet 243 is located at the rear side of the air inlet 242, the second air outlet 243 is located at the front side of the first air outlet 244, and the second air outlet 243 is located under the motor controller 181. Among them, the opening direction of the air inlet 242 faces forward, the opening direction of the second air outlet 243 faces downward, and the opening direction of the first air outlet 244 faces backward. Through the above settings, during the running of the electric motorcycle 100, air can enter the air inlet 242 better, so that the air can take away the heat of the radiator 191, the motor controller 181, the water pump 192, and the motor 201, and then the heat is discharged outside the electric motorcycle 100 through the second air outlet 243 and the first air outlet 244, improving the heat dissipation effect of the electric motorcycle 100. In addition, during the running of the electric motorcycle 100, mud and water will enter the air intake assembly 24 from the air inlet 242. By setting the opening of the second air outlet 243 downward, the mud and water can be discharged from the second air outlet 243, effectively preventing the pollution and blockage of the air intake assembly 24 by mud and water, which is beneficial to improving the air intake effect of the air intake assembly 24, and further improving the heat dissipation effect and service life of the electric motorcycle 100.

[0026] In this embodiment, the opening of the first air outlet 244 is arranged to face backward and towards the motor 201, so that the motor 201 can be better cooled and the heat dissipation effect of the motor 201 can be improved. The opening of the second air outlet 243 is smaller than that of the first air outlet 244. By the above method, the air volume discharged from the second air outlet 243 can be reduced, so that more air can be delivered to the first air outlet 244, and further the heat dissipation effects of the motor controller 181, the water pump 192 and the motor 201 can be better. Specifically, along the front-rear direction of the electric motorcycle 100, the motor controller 181 is arranged on the front side of the motor 201, the water pump 192 is arranged on the rear side of the motor controller 181, and the water pump 192 is arranged on the front side of the motor 201. The smaller opening of the second air outlet 243 can make the air better delivered to the water pump 192 and the motor 201 located at the rear side of the motor controller 181, so as to improve the heat dissipation effects of the water pump 192 and the motor 201, and further improve the heat dissipation effect and service life of the electric motorcycle 100.

[0027] In this embodiment, along the up-down direction of the electric motorcycle 100, the position of the second air outlet 243 is at the lowest point of the body cover 12, so that mud and water can flow out of the air intake assembly 24 better, effectively preventing the pollution and blockage of the air intake assembly 24 by mud and water, which is beneficial to improving the air intake effect of the air intake assembly 24, and further improving the heat dissipation effect and service life of the electric motorcycle 100.

[0028] As Figures 3 to 4 shown, as an implementation method, the electric motorcycle 100 includes a first projection plane 101 perpendicular to the up-down direction and a second projection plane 102 perpendicular to the left-right direction, and the second projection plane 102 is perpendicular to the first projection plane 101. Specifically, the air intake duct 241 is arranged substantially parallel to the first projection plane 101.

[0029] As an implementation, the air inlet 242 is provided with a plurality of air inlet inclined surfaces 245. Along the up-down direction and left-right direction of the electric motorcycle 100, the plurality of air inlet inclined surfaces 245 are distributed along the up-down direction and left-right direction. The air inlet inclined surface 245 can prevent some mud and water from entering the air inlet assembly 24, thereby effectively preventing the pollution and blockage of the air inlet assembly 24 by mud and water, which is beneficial to improving the air inlet effect of the air inlet assembly 24, and further improving the heat dissipation effect and service life of the electric motorcycle 100. Specifically, the air inlet inclined surface 245 is substantially perpendicular to the second projection plane 102. Along the left-right direction of the electric motorcycle 100, the projection of the air inlet inclined surface 245 on the second projection plane 102 is the first projection line, and the projection of the first projection plane 101 on the second projection plane 102 is the second projection line. The acute angle & formed by the first projection line and the second projection line is greater than or equal to 30° and less than or equal to 50°. At this time, the air inlet inclined surface 245 can effectively prevent some mud and water from entering the air inlet assembly 24, thereby effectively preventing the pollution and blockage of the air inlet assembly 24 by mud and water, which is beneficial to improving the air inlet effect of the air inlet assembly 24, and further improving the heat dissipation effect and service life of the electric motorcycle 100.

[0030] In this embodiment, along the up-down direction of the electric motorcycle 100, from top to bottom, the acute angle between the first projection line and the second projection line gradually decreases, that is, the slope of the air inlet inclined surface 245 in the upper part is larger than that of the air inlet inclined surface 245 in the lower part. Specifically, along the up-down direction of the electric motorcycle 100, the slopes of the plurality of air inlet inclined surfaces 245 gradually decrease from top to bottom. Also, since the trajectory of mud and water entering the air inlet assembly 24 is basically a parabola, through the above settings, it can effectively block mud and water from entering the air inlet assembly 24, thereby being beneficial to improving the air inlet effect of the air inlet assembly 24, and improving the heat dissipation effect and service life of the electric motorcycle 100.

[0031] As an implementation, the air inlet assembly 24 and the vehicle frame 11 can be fixedly connected by bolts or the like, and the air inlet assembly 24 and the body covering 12 can be fixedly connected by bolts or buckles or the like, so as to realize a stable connection between the air inlet assembly 24 and the vehicle frame 11, and realize a stable connection between the air inlet assembly 24 and the body covering 12, improve the air inlet effect of the air inlet assembly 24 during the driving process of the electric motorcycle 100, and further improve the heat dissipation effect and service life of the electric motorcycle 100.

[0032] As an implementation, the air intake assembly 24 further includes a first side plate 246, a second side plate, and a bottom plate 248. The first side plate 246 is disposed on the left side of the electric motorcycle 100, the second side plate is disposed on the right side of the electric motorcycle 100, and the bottom plate 248 is disposed on the lower side of the electric motorcycle. One side of the bottom plate 248 is connected to the first side plate 246, and the other side of the bottom plate 248 is connected to the second side plate. The first side plate 246, the second side plate, and the bottom plate 248 together form an air intake duct 241. The first side plate 246, the second side plate, and the bottom plate 248 can be integrally formed, thereby improving the sealing performance of the air intake assembly 24, improving the air intake effect of the air intake assembly 24 during the driving process of the electric motorcycle 100, and improving the heat dissipation effect and service life of the electric motorcycle 100. The first side plate 246, the second side plate, and the bottom plate 248 can also be fixedly connected, which is convenient for processing the air intake assembly 24 and replacing the air intake assembly 24.

[0033] As an implementation, the air inlet 242 includes a plurality of air intake holes 2421. There is a hole wall between adjacent air intake holes 2421, and adjacent air intake holes 2421 are spaced apart by the hole wall, which is convenient for air to enter the air intake assembly 24 through the plurality of air intake holes 2421 during the driving process of the electric motorcycle 100, thereby improving the heat dissipation effect and service life of the electric motorcycle 100. Specifically, along the front-rear direction of the electric motorcycle 100, the openings of the air intake holes 2421 face forward. Through the above settings, during the driving process of the electric motorcycle 100, air can better enter the air intake assembly 24 through the air intake holes 2421, so that the air can take away the heat of the radiator 191, the motor controller 181, the water pump 192, and the motor 201, and then the heat is discharged outside the electric motorcycle 100 through the second air outlet 243 and the first air outlet 244, improving the heat dissipation effect and service life of the electric motorcycle 100. Specifically, the size and shape of the air intake holes 2421 can be adjusted according to requirements or the external structure of the electric motorcycle 100, so that without changing the external structure of the electric motorcycle 100 when the air volume entering the air intake assembly 24 is sufficient, the space utilization rate and resource utilization rate of the electric motorcycle 100 are improved.

[0034] In this embodiment, an air intake inclined surface 245 is provided in each air intake hole 2421. The air intake inclined surface 245 can provide a buffering effect when air enters the air intake hole 2421, so that the resistance of the air intake assembly 24 during the driving process of the electric motorcycle 100 is smaller, and the driving speed of the electric motorcycle 100 is improved. In addition, the air intake inclined surface 245 can effectively prevent some muddy water, etc. from entering the air intake assembly 24 through the air intake holes 2421, thereby effectively preventing the pollution and blockage of the air intake assembly 24 by muddy water, etc., which is beneficial to improving the air intake effect of the air intake assembly 24, and further improving the heat dissipation effect and service life of the electric motorcycle 100.

[0035] Specifically, along the up-and-down direction of the electric motorcycle 100, from top to bottom, the acute angle between the first projection line and the second projection line gradually decreases. That is, the slope of the air inlet slope 245 of the upper air inlet hole 2421 is larger than that of the air inlet slope 245 of the lower air inlet hole 2421. Also, since the trajectory of mud and water entering the air inlet assembly 24 is basically parabolic, through the above settings, mud and water can be effectively blocked from entering the air inlet assembly 24, which is beneficial to improving the air inlet effect of the air inlet assembly 24, and enhancing the heat dissipation effect and service life of the electric motorcycle 100.

[0036] As an implementation method, a first air inlet is provided on the left side of the electric motorcycle 100, and a second air inlet is provided on the right side, facilitating air to enter the air inlet assembly 24 through the first air inlet and the second air inlet during the driving process of the electric motorcycle 100. Through the above setting method, the air intake volume can be increased, thereby cooling the radiator 191, the motor controller 181, the water pump 192, and the motor 201 in the form of air cooling, which is beneficial to improving the heat dissipation effect of the electric motorcycle 100 and thus enhancing the service life of the electric motorcycle 100.

[0037] In this embodiment, the first air inlet includes a plurality of first air inlet holes, and a hole wall is provided between adjacent first air inlet holes. The adjacent first air inlet holes are spaced apart by the hole wall, facilitating air to enter the air inlet assembly 24 through the plurality of first air inlet holes during the driving process of the electric motorcycle 100, thereby improving the heat dissipation effect and service life of the electric motorcycle 100. Specifically, along the front-back direction of the electric motorcycle 100, the openings of the first air inlet holes face forward. Through the above settings, during the driving process of the electric motorcycle 100, air can better enter the air inlet assembly 24 through the first air inlet holes, so that the air takes away the heat of the radiator 191, the motor controller 181, the water pump 192, and the motor 201, and then the heat is discharged outside the electric motorcycle 100 through the second air outlet 243 and the first air outlet 244, improving the heat dissipation effect and service life of the electric motorcycle 100. Specifically, the size and shape of the first air inlet holes can be adjusted according to requirements or the external structure of the electric motorcycle 100, so that without changing the external structure of the electric motorcycle 100 when the air volume entering the air inlet assembly 24 is sufficient, the space utilization rate and resource utilization rate of the electric motorcycle 100 are improved.

[0038] Specifically, a first air inlet slope is provided in each first air inlet hole. The first air inlet slope can provide a buffering effect when air enters the first air inlet hole, so that the resistance of the air inlet assembly 24 during the running of the electric motorcycle 100 is smaller, and the running speed of the electric motorcycle 100 is increased. In addition, the first air inlet slope can effectively prevent part of the mud and water from entering the air inlet assembly 24 through the first air inlet hole, thereby effectively preventing the pollution and blockage of the air inlet assembly 24 by the mud and water, which is beneficial to improving the air inlet effect of the air inlet assembly 24, and further improving the heat dissipation effect and service life of the electric motorcycle 100.

[0039] In this embodiment, the second air inlet includes a plurality of second air inlet holes, and a hole wall is provided between adjacent second air inlet holes. The adjacent second air inlet holes are spaced apart by the hole wall, which is convenient for air to enter the air inlet assembly 24 through the plurality of second air inlet holes during the running of the electric motorcycle 100, thereby improving the heat dissipation effect and service life of the electric motorcycle 100. Specifically, along the front-back direction of the electric motorcycle 100, the openings of the second air inlet holes are arranged forward. Through the above settings, during the running of the electric motorcycle 100, air can better enter the air inlet assembly 24 through the second air inlet holes, so that the air takes away the heat of the radiator 191, the motor controller 181, the water pump 192 and the motor 201, and then the heat is discharged outside the electric motorcycle 100 through the first air outlet 244 and the first air outlet 244, improving the heat dissipation effect and service life of the electric motorcycle 100. Specifically, the size and shape of the second air inlet holes can be adjusted according to requirements or the external structure of the electric motorcycle 100, so that without changing the external structure of the electric motorcycle 100 when the air volume entering the air inlet assembly 24 is sufficient, the space utilization rate and resource utilization rate of the electric motorcycle 100 are improved.

[0040] Specifically, a second air inlet slope is provided in each second air inlet hole. The second air inlet slope can provide a buffering effect when air enters the second air inlet hole, so that the resistance of the air inlet assembly 24 during the running of the electric motorcycle 100 is smaller, and the running speed of the electric motorcycle 100 is increased. In addition, the second air inlet slope can effectively prevent part of the mud and water from entering the air inlet assembly 24 through the second air inlet hole, thereby effectively preventing the pollution and blockage of the air inlet assembly 24 by the mud and water, which is beneficial to improving the air inlet effect of the air inlet assembly 24, and further improving the heat dissipation effect and service life of the electric motorcycle 100.

[0041] Such as Figure 5As shown, as an implementation, the electric motorcycle 100 further includes a footrest assembly 25 and a steering assembly 26. The steering assembly 26 is connected to the suspension assembly 14, and the steering assembly 26 is disposed on the frame 11 for controlling the moving direction of the electric motorcycle 100. Specifically, the steering assembly 26 is connected to the front suspension 141, so as to control the steering of the front wheel 131 through the front suspension 141, and further control the moving direction of the electric motorcycle 100. The footrest assembly 25 is at least partially disposed on the frame 11 for placing the driver's feet and providing support for the driver's feet. Specifically, the footrest assembly 25 is connected to the frame 11 by fixing means such as bolts, so as to achieve a stable connection between the footrest assembly 25 and the frame 11. In this embodiment, the footrest assembly 25 is at least partially disposed between the steering assembly 26 and the saddle assembly 15, and the footrest assembly 25 extends substantially along the front-rear direction of the electric motorcycle 100.

[0042] As an implementation, in a first projection plane 101 perpendicular to the up-down direction of the electric motorcycle 100, the axis line of the front wheel 131 has a first projection line in the first projection plane 101 along the up-down direction, and the axis line of the rear wheel 132 has a second projection line in the first projection plane 101 along the up-down direction of the electric motorcycle 100; the front end of the footrest assembly 25 has a third projection line in the first projection plane 101 along the up-down direction of the electric motorcycle 100; the rear end of the footrest assembly 25 has a fourth projection line in the first projection plane 101 along the up-down direction of the electric motorcycle 100. The footrest assembly 25 is disposed substantially parallel to the first projection plane 101.

[0043] In the front-rear direction of the electric motorcycle 100, the distance between the first projection line and the second projection line is a first distance D1, the distance between the third projection line and the fourth projection line is a second distance D2, and the ratio of the first distance D1 to the second distance D2 is greater than or equal to 4.4 and less than or equal to 6.7. Wherein, the first distance D1 is the shortest distance between the first projection line and the second projection line, and the second distance D2 is the shortest distance between the third projection line and the fourth projection line. Within this distance range, the footrest assembly 25 can provide more comfortable support for the driver's feet, thereby improving the driving comfort of the electric motorcycle 100, and further improving the human-machine interaction of the electric motorcycle 100. In addition, when meeting the requirement of providing comfortable support for the driver's feet, the structure of the electric motorcycle 100 is more compact, which can improve the overall compactness of the electric motorcycle 100, so that the electric motorcycle 100 has better mobility during driving and improves the driving operability of the driver.

[0044] In this embodiment, the ratio of the first distance D1 to the second distance D2 is greater than or equal to 5 and less than or equal to 6. When the ratio of the first distance D1 to the second distance D2 is greater than or equal to 5 and less than or equal to 6, the footrest assembly 25 can provide more comfortable support for the driver's feet, thereby improving the driving comfort of the electric motorcycle 100, and further improving the human-machine interaction of the electric motorcycle 100. In addition, when meeting the requirement of providing comfortable support for the driver's feet, the structure of the electric motorcycle 100 is more compact, which can improve the overall compactness of the electric motorcycle 100, so that the electric motorcycle 100 has better maneuverability during driving and improves the driving operability of the driver.

[0045] In this embodiment, the ratio of the first distance D1 to the second distance D2 is 5.4. When the ratio of the first distance D1 to the second distance D2 is 5.4, the footrest assembly 25 can provide more comfortable support for the driver's feet, thereby improving the driving comfort of the electric motorcycle 100, and further improving the human-machine interaction of the electric motorcycle 100. In addition, when meeting the requirement of providing comfortable support for the driver's feet, the structure of the electric motorcycle 100 is more compact, which can improve the overall compactness of the electric motorcycle 100, so that the electric motorcycle 100 has better maneuverability during driving and improves the driving operability of the driver.

[0046] As an implementation, the electric motorcycle 100 further includes a saddle assembly 15. The saddle assembly 15 includes a saddle 151 and a saddle cover 152, and the saddle 151 and the saddle cover 152 are rotatably connected. A seating point 1521 is provided on the saddle cover 152. Herein, the seating point 1521 refers to the point where the driver sits on the saddle cover 152. The steering assembly 26 includes a grip mechanism 261. The grip mechanism 261 can be a steering handle 2611, and the steering handle 2611 is arranged on both sides of the electric motorcycle 100. The steering handle 2611 is substantially a cylinder. When the electric motorcycle 100 is going straight, the steering handle 2611 is in a balanced state. At this time, the steering handle 2611 extends substantially along the left-right direction of the electric motorcycle 100. Along the up-down direction of the electric motorcycle 100, the projection of the axis line of the steering handle 2611 on the first projection plane 101 is the fifth projection line, and the projection of the seating point 1521 on the first projection plane 101 is the first projection point. Along the front-back direction of the electric motorcycle 100, the distance between the fifth projection line and the first projection line is the third distance D3, and the shortest distance between the first projection point and the first projection line is the fourth distance D4. Herein, the third distance D3 is the shortest distance between the fifth projection line and the first projection line.

[0047] Specifically, the ratio of the first distance D1 to the third distance D3 is greater than or equal to 2.4 and less than or equal to 3.7. At this time, the steering assembly 26 can provide a relatively comfortable grip for the driver's hand, thereby improving the driving comfort of the electric motorcycle 100 and further enhancing the human-machine interaction of the electric motorcycle 100. The ratio of the first distance D1 to the fourth distance D4 is greater than or equal to 1.2 and less than or equal to 1.9. At this time, the saddle assembly 15 can provide a relatively comfortable support for the driver, thereby improving the driving comfort of the electric motorcycle 100 and further enhancing the human-machine interaction of the electric motorcycle 100.

[0048] Specifically, the ratio of the first distance D1 to the third distance D3 is greater than or equal to 2.8 and less than or equal to 3.3. At this time, the steering assembly 26 can provide a relatively comfortable grip for the driver's hand, thereby improving the driving comfort of the electric motorcycle 100 and further enhancing the human-machine interaction of the electric motorcycle 100. The ratio of the first distance D1 to the fourth distance D4 is greater than or equal to 1.4 and less than or equal to 1.7. At this time, the saddle assembly 15 can provide a relatively comfortable support for the driver, thereby improving the driving comfort of the electric motorcycle 100 and further enhancing the human-machine interaction of the electric motorcycle 100.

[0049] In this embodiment, the ratio of the first distance D1 to the third distance D3 is 3. At this time, the steering assembly 26 can provide a more comfortable grip for the driver's hand, thereby improving the driving comfort of the electric motorcycle 100 and further enhancing the human-machine interaction of the electric motorcycle 100. The ratio of the first distance D1 to the fourth distance D4 is 1.5. At this time, the saddle assembly 15 can provide a more comfortable support for the driver, thereby improving the driving comfort of the electric motorcycle 100 and further enhancing the human-machine interaction of the electric motorcycle 100.

[0050] Specifically, when the ratio of the first distance D1 to the third distance D3 is 3 and the ratio of the first distance D1 to the fourth distance D4 is 1.5, the structure of the electric motorcycle 100 is more stable and compact, thereby improving the overall stability and compactness of the electric motorcycle 100 and further enhancing the service life and driving operability of the electric motorcycle 100.

[0051] As an implementation, a foot guard plate 121 is provided on one side of the body cover 12 close to the driver's feet, and the foot guard plate 121 extends substantially along the up and down direction of the electric motorcycle. Along the front and rear direction of the electric motorcycle 100, the front side of the saddle assembly 15, the rear side of the foot guard plate, and the upper side of the footrest assembly 25 together form an accommodation space 27.

[0052] Along the left - right direction of the electric motorcycle 100, within a second projection plane 102 perpendicular to the left - right direction of the electric motorcycle 100, the accommodation space 27 has a first projection plane in the second projection plane 102, and the area of the first projection plane is greater than or equal to 0.09 square meters and less than or equal to 0.13 square meters. When the area of the first projection plane is greater than or equal to 0.09 square meters and less than or equal to 0.13 square meters, the accommodation space 27 can provide a relatively comfortable placement space for the driver's feet, thereby improving the driving comfort of the electric motorcycle 100 and further improving the human - machine interaction of the electric motorcycle 100.

[0053] Specifically, the area of the first projection plane is greater than or equal to 0.1 square meters and less than or equal to 0.12 square meters. When the area of the first projection plane is greater than or equal to 0.1 square meters and less than or equal to 0.12 square meters, the accommodation space 27 can provide a relatively comfortable placement space for the driver's feet, thereby improving the driving comfort of the electric motorcycle 100 and further improving the human - machine interaction of the electric motorcycle 100.

[0054] In this embodiment, the area of the first projection plane is 0.11 square meters. At this time, the accommodation space 27 can provide a more comfortable placement space for the driver's feet, thereby improving the driving comfort of the electric motorcycle 100 and further improving the human - machine interaction of the electric motorcycle 100. In addition, when the area of the fifth projection plane is 0.11 square meters, while meeting the requirement of providing a comfortable placement space for the driver's feet, the structure of the electric motorcycle 100 is more compact, which can improve the overall compactness of the electric motorcycle 100, so that the electric motorcycle 100 has better maneuverability during driving and improves the driver's driving operability.

Specifically, along the up-down direction of the electric motorcycle 100, the motor controller 181 is arranged below the footrest assembly 25, and the motor controller 181 is wrapped by the first space, the footrest assembly 25, and the air intake assembly 24, so as to ensure the stability of the motor controller 181 and enable the motor controller 181 to better control the motor 201. The power supply device 17 includes a power storage element 171. The power storage element 171 is installed on the vehicle frame 11 and is located in the saddle 151, and is used to provide power for the electric motorcycle 100.

Along the front-back direction of the electric motorcycle 100, the distance between the ninth projection line and the eighth projection line is L3. The difference between L3 and L1 is greater than or equal to 270 mm and less than or equal to 510 mm. At this time, in the electric motorcycle 100, since the weights of the motor controller 181 and the motor 201 are relatively heavy, through the above settings, the positions of the motor controller 181 and the motor 201 can be reasonably arranged, so that the motor controller 181 and the motor 201 are arranged along the front-back direction of the electric motorcycle 100, thereby enabling the electric motorcycle 100 to maintain a relatively stable state, improving the stability and balance of the electric motorcycle 100, and further keeping stable when the electric motorcycle 100 is stationary and driving, and improving driving safety.
