Abstract

An electric skateboard comprises a deck, a pair of rear wheels, and a front wheel having a front wheel diameter. A deck height is defined by the distance between the bottom side of the deck and the ground. The front wheel diameter is greater than the deck height. One or more motors is operable to drive the front wheel. A control module is in communication with the one or more motors, and is operable to effect acceleration and deceleration of the one or more motors. A rechargeable battery pack is configured to provide power to the one or more motors. A controller is in wireless communication with the control module. The controller is configured to receive user input and to transmit the user input to the control module.

Claims

1. A skateboard, comprising:

(a) a deck having a front end, a back end, a top side, and a bottom side;

(b) a pair of wheels secured to a truck assembly, wherein the truck assembly is secured to the deck;

(c) a front wheel having a front wheel diameter; and

(d) a deck height defined by the distance between the bottom side of the deck and the ground when the pair of wheels and the front wheel are in contact with the ground;

wherein the front wheel diameter is greater than the deck height.

2. The skateboard of claim 1, further comprising one or more motors, wherein the one or more motors are operable to drive one or more of the pair of wheels or the front wheel.

3. The skateboard of claim 2, wherein at least one of the one or more motors comprises a cone member, wherein the cone member is engaged with the front wheel of the skateboard, wherein the cone member is configured to transfer torque to the front wheel.

4. The skateboard of claim 3, wherein the cone member is configured to transfer torque to the front wheel through frictional engagement with the front wheel.

5. The skateboard of claim 3, wherein the cone member is configured to transfer torque to the front wheel through geared engagement with the front wheel.

6. The skateboard of claim 2, further comprising one or more belts, wherein each of the one or more belts is configured to transfer torque from the one or more motors to the front wheel.

7. The skateboard of claim 2, wherein at least one of the one or more motors comprises a hub motor located at least partially within the front wheel.

8. The skateboard of claim 2, further comprising a remote control, wherein the remote control is operable to variably control acceleration of the skateboard.

9. The skateboard of claim 8, further comprising a control module in communication with the one or more motors, wherein the remote control is in wireless communication with the control module.

10. The skateboard of claim 8, wherein the remote control is configured to receive deceleration input from a user, wherein the deceleration input is operable to cause a ramping deceleration followed by a plateau deceleration of the skateboard.

11. The skateboard of claim 8, further comprising a control module in communication with the controller and the one or more motors, wherein the controller further comprises a reset button, wherein the reset button is operable to reset one or more circuits within the control module.

12. The skateboard of claim 8, wherein the controller further comprises a visual display, wherein the visual display is configured to display information relating to the skateboard.

13. The skateboard of claim 12, wherein the displayed information relates to one or more of speed, distance traveled, or positioning of the skateboard.

14. The skateboard of claim 12, further comprising a battery pack, wherein the displayed information relates to voltage level in the battery pack.

15. The skateboard of claim 1, wherein the deck has a slot formed at the front end of the deck wherein at least a portion of the front wheel is positioned within the slot.

16. The skateboard of claim 1, further comprising a suspension system coupled with the front wheel.

17. The skateboard of claim 1, further comprising a pair of headlamps.

18. The skateboard of claim 1, further comprising a rechargeable battery pack.

19. An electric skateboard, comprising:

(a) a deck having a front end, a back end, a top side, and a bottom side;

(b) a pair of wheels secured to a truck assembly, wherein the truck assembly is secured to the deck;

(c) a front wheel having a front wheel diameter;

(d) a deck height defined by the distance between the bottom side of the deck and the ground when the pair of wheels and the front wheel are in contact with the ground, wherein the deck height is less than the front wheel diameter;

(e) one or more motors in mechanical communication with the front wheel, wherein the one or more motors are operable to drive the front wheel;

(f) a control module in communication with the one or more motors, wherein the control module is operable to effect acceleration and deceleration of the one or more motors;

(g) a battery pack, wherein the battery pack is configured to provide power to the one or more motors; and

(h) a controller in wireless communication with the control module, wherein the controller is configured to receive user input, wherein the controller is further configured to transmit user input to the control module.

20. A skateboard system, comprising:

(a) plurality of skateboards, each skateboard comprising;

(i) a deck,

(ii) a plurality of wheels,

(iii) at least one motor,

(iv) at least one battery configured to provide power to the at least one motor,

(v) a control module in communication with the at least one motor, wherein the control module is operable to effect acceleration of the at least one motor; and

(b) a plurality of controllers, wherein each controller of the plurality of controllers is associated with a skateboard of the plurality of skateboards to create an associated set, wherein each controller is in wireless communication with the control module of its associated skateboard, wherein the controller is not operable to control any of the skateboards outside of its associated set.
