A resilient anti-tip wheel suspension includes a wheel coupled to a first mounting bracket. A second mounting bracket is adapted to be rigidly mounted to a wheelchair. Upper and lower bars each have front and rear ends that are pivotally connected to the second mounting bracket and the first mounting bracket, respectively, so as to form a parallelogram configuration.
