A method, system and apparatus for carrying a user including a board for supporting the user, a ground-contacting member coupled with the board, a motorized drive assembly coupled with the ground-contacting member and one or more sensors coupled with the drive assembly. In operation, the drive assembly adjusts the velocity of the ground-contacting member based on one or more distances of the board from a surface below the board as detected by the sensors. As a result, the system is able to maintain a desired velocity when ascending, descending or traversing uneven ground without the need for excessive and sometimes impossible tilting of the board.

1. A vehicle for carrying a user comprising: a board having a plurality of detached sections coupled together by one or more hinges such that the sections are able to pivot about the hinges;a single ground-contacting member coupled with the board; anda motorized drive assembly coupled with the ground-contacting member, wherein the drive assembly adjusts the velocity of the ground-contacting member, wherein the ground-contacting member rotates about an axle and the axle acts as a pin of the hinges such that the sections pivot about the axle. 2. The vehicle of claim 1, wherein the ground-contacting member rotates about a hollow axle having an exposed channel that extends though the hollow axle. 3. The vehicle of claim 1, wherein the board has one or more additional hinges that with the one or more hinges rotatably couple together three of the sections of the board. 4. The vehicle of claim 1, wherein the board comprises one or more handles that are each defined by one of the group consisting of a hole that extends through the board or a channel that extends only partially into the bottom of the board. 5. A vehicle for carrying a user comprising: a board having a plurality of detached sections coupled together by one or more hinges such that the sections are able to pivot about the hinges;a single ground-contacting member coupled with the board; anda motorized drive assembly coupled with the ground-contacting member, wherein the drive assembly adjusts the velocity of the ground-contacting member, wherein two or more of the sections of the board house at least one electronic component of the drive assembly and the board further comprises one or more interfaces that electrically couple together two or more of the electronic components from different ones of the two or more of the sections when the board is in an unfolded position. 6. The vehicle of claim 1, further comprising one or more sensors coupled with the drive assembly, wherein the drive assembly adjusts the velocity of the ground-contacting member based on one or more distances of the board from a surface below the board as detected by the sensors. 7. The vehicle of claim 6, wherein the board is elongated along a dimension in a fore-aft plane that aligns with the forward and reverse directions of travel of the vehicle. 8. The vehicle of claim 7, wherein one or more fore sensors of the sensors are positioned at the fore end of the elongated dimension of the board and one or more aft sensors of the sensors are positioned at the aft end of the elongated dimension of the board. 9. The vehicle of claim 7, wherein the board as balanced by the ground-contacting member is unstable with respect to tipping along the fore-aft plane when the motorized drive assembly is not in operation, and the motorized drive assembly is configured to automatically balance the board with respect to tipping along the fore-aft plane when the motorized drive assembly is in operation. 10. The vehicle of claim 6, wherein the drive assembly adjusts the velocity of the ground-contacting member based on the one or more distances by using the distances to calculate a pitch of the board with respect to the surface and applying a force to the ground-contacting member in order to achieve a predefined velocity of the ground-contacting member that corresponds to the pitch. 11. The vehicle of claim 10, wherein the pitch is calculated by determining a difference between the one or more distances and an average of two or more of the distances such that the drive assembly adjusts for unevenness in the surface. 12. A method of operating a vehicle having an elongated board, the method comprising: providing a vehicle comprising: a board having a plurality of detached sections coupled together by one or more hinges such that the sections are able to pivot about the hinges;a single ground-contacting member coupled with the board; anda motorized drive assembly coupled with the ground-contacting member, wherein the drive assembly adjusts the velocity of the ground-contacting member;moving the board between an unfolded position into a folded position by pivoting the sections about the hinges, wherein ends of two of the sections that are on opposite sides of the board in the unfolded position are closer together in the folded position, wherein the ground-contacting member rotates about an axle and the axle acts as a pin of the hinges such that the sections pivot about the axle. 13. The method of claim 12, wherein the ground-contacting member rotates about a hollow axle having an exposed channel that extends though the hollow axle. 14. The method of claim 12, wherein the board has one or more additional hinges that with the one or more hinges rotatably couple together three of the sections of the board. 15. The method of claim 12, wherein the board comprises one or more handles that are each defined by one of the group consisting of a hole that extends through the board or a channel that extends only partially into the bottom of the board. 16. The method of claim 12, wherein the vehicle further comprises one or more sensors coupled with the drive assembly, wherein the drive assembly adjusts the velocity of the ground-contacting member based on one or more distances of the board from a surface below the board as detected by the sensors. 17. The method of claim 16, wherein the board is elongated along a dimension in a fore-aft plane that aligns with the forward and reverse directions of travel of the vehicle. 18. The method of claim 17, wherein one or more fore sensors of the sensors are positioned at the fore end of the elongated dimension of the board and one or more aft sensors of the sensors are positioned at the aft end of the elongated dimension of the board. 19. The method of claim 17, wherein the board as balanced by the ground-contacting member is unstable with respect to tipping along the fore-aft plane when the motorized drive assembly is not in operation, and the motorized drive assembly is configured to automatically balance the board with respect to tipping along the fore-aft plane when the motorized drive assembly is in operation. 20. The method of claim 16, wherein the drive assembly adjusts the velocity of the ground-contacting member based on the one or more distances by using the distances to calculate a pitch of the board with respect to the surface and applying a force to the ground-contacting member in order to achieve a predefined velocity of the ground-contacting member that corresponds to the pitch. 21. The method of claim 20, wherein the pitch is calculated by determining a difference between the one or more distances and an average of two or more of the distances such that the drive assembly adjusts for unevenness in the surface. 22.
