Abstract: A power supply assembly is provided for a Personalized Motorized Vehicle (PMV) including a detachable mounting assembly therefor which facilitates the ease of attachment of a Power Supply Unit (PSU) to a main structural frame of the PMV, provides a positive electrical and structural connection therebetween, and integrates the power supply assembly with the external geometry of the PMV to provide an aesthetically pleasing external appearance. The power supply assembly includes a pair of PSUs, each unit having a housing structure which includes at least one segment projecting from a center body portion thereof. A segment of one PSU unit overlaps a segment of another PSU unit and another segment of one PSU overlaps a portion of the main structural frame. Electrical connectors are disposed in combination with the overlapping housing segments for electrically coupling the PSUs and at least one PSU to the PMV.

Abstract: A personal mobility vehicle is steered by handlebars. A lever is mounted on the handlebars and rotatable in either of two opposite directions by the hands holding the handlebars. A potentiometer connected to the lever comprises a wiper on a resistive track, centered by a spring. The track has a central null area formed by material of lower resistance, so that the output voltage is constant. When the lever is moved away from the centered position, the wiper moves along the track and the output voltage rises or falls. A controller controls the speed and direction of the vehicle in response to the output voltage of the potentiometer. When the wiper is on the null area, the controller stops the vehicle. The size of the null area facilitates ensuring the centered position coincides with the null area, so the vehicle stops when the lever is released.
