Abstract
The motorized stroller apparatus features double wheels at all four corners for lesser rolling resistance over various surfaces. The front wheel sets are fully pivotal. The on/off switch provides more than one function. In the on position, the motor is connected with the axle. The motor thereby serves as an automatic brake until the spring biased throttle lever is actuated. Spring bias causes throttle shut off when released. In the off position, the switch disengages the axle from the motor, thereby allowing for stroller function in a non-powered mode. The optional dual rear wheel sets drive encourages the stroller to track straight, as opposed to single wheel set drive which would continually encourage angular propulsion.
