IN ir.... (57) : A self-balancing board is provided, comprising a platfoiin having a first foot deck portion to substantially support a 0 ---- first foot of a rider, and a second foot deck portion to substantially support a second foot of the rider. A wheel assembly is positioned IN between the first foot deck portion and the second foot deck portion along a longitudinal axis of the platform, and comprises a wheel c:::, having a rotation axis that is generally orthogonal to the longitudinal axis of the platfoiin, and a motor unit driving the wheel. An ei orientation sensor senses the orientation of the platform. A controller receives data from the orientation sensor and controls the mo - 0 tor unit in response to the received data. At least one suspension interface between the platform and the wheel assembly has a single degree of freedom generally orthogonal to the rotation axis of the wheel and to the longitudinal axis of the platform, and biases the platfoiin towards a rest position.
