A lightweight folding motorized chair with mechanical traction steering and braking. A folding frame supports the traction wheels and the drive system with hinged frame members configured to mechanically fold the control levers, wheels and periphery components into a substantially flat configuration for easy storage in small spaces. A mix of weight saving choices including: structural materials； mechanical traction control system； lithium ion battery； and overall lightweight design keeps the folding motorized chair at a size and weight that a person can lift into the trunk of a car.
