A wheel suspension system including a wheel support pivotally attached to a vehicle frame at two, laterally-spaced locations, the wheel support being pivotal between an uppermost and a lowermost position. The wheel support is biased to a position intermediate of the uppermost and lowermost positions by a spring. The spring urges apart a spring support of the wheel support from the vehicle frame, the spring support being below the rotational axis of the wheel. The pivotal axes of the pivotal attachments are located below the rotational axis of the wheel.
