ABSTRACT:
A stable wheel assembly has wheels, a connector, a wheel stand with a bracket and a resilient body. Each wheel has a center. The connector has two spindles and two protrusions. Each protrusion has a free end and an upright step integrally formed with the free end of the protrusion. The upright steps on the protrusions are mated with each other. The bracket is pivotally mounted on two protrusions with a fastener. When the scooter or electric motorcycle mounted the stable wheel assembly run on an uneven surface, the wheels is raised up and the protrusion connected to the raised wheels is pivoted around the fastener mounted inside the protrusion and bracket. Therefore, a scooter or an electric motorcycle with the stable wheel assembly can be prevented from turning over.
