Abstract
For the elderly people, it is developed the caring type ultra-lightweight electric tricycle: pico-EV using the bamboo with engineering examination. The EV is easy for shopping and movement, and it runs in low velocity. In order to raise the rigidity and strength of parts, the angle ply laminated plates which carried out for a thin bamboo fiber sheet to arbitrary angles was developed uniquely. Since the newest EV is a decomposition type, it can be carried as baggage in the airplane of an international airline and a domestic one. In this paper, the pico-EV which developed by students in about ten months, it makes a reference with the past circumstances.
