Abstract

The paper develops the conceptual design of a lightweight electric scooter with high pliability and portability characteristics. Primarily, the paper focuses on the development and virtual representation of the scooter concept through iterative improvements and the elimination of the weaknesses of design of the previous solution. After three successive iterations a final version is obtained that fully meets the requirements list. Secondly, during concept development, an evaluation of these concept variants is proposed, based on technical and economic criteria. Finally, a positioning matrix of the proposed product is obtained in relation to existing products on the market. A discussion of solutions based on the requirements list is offered also. Several conclusions distinguish the main points and results of the paper.
