The challenges of the global climate as well as the increasing needs of transportation and shipping logistics have forced various manufacturers to start transforming the transportation technology from fossil fuel-based to electric vehicles (EVs). The problem is that currently most companies still have a lot of assets in the form of trucks that run on diesel fuel. The conversion process of conventional trucks to electric trucks is solution for the needs of logistics delivery and the limited funds. The conversion process requires a comprehensive analysis of various market aspects before it is truly commercialized. This research focuses on analyzing market aspect in the feasibility study of converting diesel trucks into electric trucks. The purpose of the market aspect analysis in this study is to determine market conditions, market acceptances, and the position of competitors in the electric truck business. Based on the analysis of market aspects on the feasibility, it is concluded that the potential customers of electric truck from the conversion of diesel truck users are quite promising. So far not many direct competitors have played in the electric truck conversion area. The next step is an analysis of the technological aspect.
