摘要
A skateboard is disclosed that includes a rear wheel system and a front wheel system. The rear wheel system includes a pair of rear wheels that are mounted on a rear axle that is coupled to a rear truck that is attached to an underside of a rear portion of a board. The rear wheel system permits each of the pair of rear wheels to alternately move toward a front portion of the board responsive to a force alternately urging each of the pair of rear wheels toward the underside of the board. The front wheel system includes a pair of front wheels that are mounted on a front axle that is rotatably attached to a mid-truck such that the front axle is movable about a first axis of rotation. The mid-truck is rotatably attached to an attachment base that is secured to an underside of the front portion of the board such that the mid-truck is rotatable about a second axis of rotation. The movement of the front axle about the first axis and the rotation of the mid-truck about the second axis provides that each of the pair of front wheels maintains substantially equal force against the ground during turning even when the rear truck is stationary with respect to the ground.
