1. An electric vehicle, comprising:
a board including first and second deck portions each configured to receive a left or right foot of a rider oriented generally perpendicular to a direction of travel of the board;
a wheel assembly including a rotatable ground-contacting element disposed between and extending above the first and second deck portions;
a motor assembly mounted to the board and configured to rotate the ground-contacting element around an axle to propel the electric vehicle;
at least one sensor configured to measure orientation information of the board;
a motor controller configured to receive orientation information measured by the sensor and to cause the motor assembly to propel the electric vehicle based on the orientation information; and
a pair of side rails respectively disposed on each lateral side of the board, each side rail including a first end portion connected to the first deck portion, a second end portion connected to the second deck portion, and a central portion disposed between the first end portion and the second end portion;
wherein a top surface of each side rail defines a generally concave shape such that a plane connecting distal edges of the end portions of the side rail is spaced apart from the central portion of the side rail.
