Abstract: A two-wheeled vehicle is provided. The two-wheeled vehicle includes a chassis having a height, a length, a width, a front and a back, a first wheel rotatably connected to the chassis, the first wheel having a perimeter, a diameter and a geometric center, and the diameter of the first wheel being at least 75% of the height of the chassis, a second wheel rotatably connected to the chassis, the second wheel having a perimeter, a diameter and a geometric center, and the diameter of the second wheel being at least 75% of the height of the chassis, and a counterweight coupled to the chassis such that the counterweight can adjust an orientation of the chassis in response to a change in pitch of the chassis about an axis passing through the geometric centers of the first and second wheels.

Abstract: A two-wheeled vehicle is provided. The two-wheeled vehicle includes a chassis having a height, a length and a width, in a first wheel rotatably connected to the chassis, the first wheel having a perimeter, a diameter and a geometric center, and the diameter of the first wheel being at least 75% of the height of the chassis, a motor for providing a drive energy to the first wheel, an axle rotated by the motor, a drive gear connected with the axle such that the drive gear rotates with a rotation of the axle, and a plurality of teeth disposed about the first wheel and mechanically engaged with the drive gear at a location closer to the perimeter of the first wheel than to the geometric center of the first wheel.
