ABSTRACT:
An improved wheelchair having electrically powered drive motors in which a battery support tray is secured within an opening in a side frame of the wheelchair. Two batteries can be supported, one on each side frame, whereupon the conventional undercarriage battery support rack may be eliminated. Each side frame of the wheelchair contains a drive motor and battery support tray and forms a self-contained assembly such that left and right hand side assemblies can be joined together by foldable links having any desired length to provide a correspondingly desired seat width.
