Abstract

A gear drive balancing scooter is provided that has a left side, a right side, and a center section located between the left and right side. The center section is coupled to the right and left sides through a gear. As the left side moves with respect to the center section, the right side moves in an opposite direction with respect to the center section. Both sides have a respective wheel motor assembly that is used to balance the scooter. To steer the scooter, the user angles one side differently than the other side. The angle of each side determines the rate and direction that each wheel motor assembly rotates. An optional staff extends upwardly from the center section to provide stability.
