Abstract
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 method for controlling the device for an electrically motorized wheel includes controlling an amount of assistance from the device of the electrically motorized wheel while travelling uphill to result in a user input requirement about equivalent to that required to propel the vehicle on a level surface.
