A system, method, and device for operations of an electrically motorized vehicle. The vehicle can utilize an electrically motorized wheel to convert a non-motorized wheeled vehicle to an electrically motorized wheeled vehicle. One system to facilitate user safety when using an electrically motorized wheel includes a proximity sensor on the electrically motorized wheel in communication with a user mobile device and a proximity alert module on the mobile device enabled to alert a user when a sensed proximity crosses a threshold.
