Life cycle environmental evaluation of a new lightweight electric-assist bicycle has been discussed in terms of materials supply, production, use and the recycling/disposal stages. The effectiveness of such a novel bicycle is compared with existing transportation from the viewpoint of environmental impact. In the life cycle environmental evaluation, photovoltaic and in-vehicle fuel cell power generations are applied as an energy source for the electric-assist bicycle. The environmental impact of the lightweight electric-assist bicycle, given its photovoltaic power supply, has a minimal environmental impact in this study. Its transportation by light truck, passenger car and the well-known two-wheel electric-assist bicycle is chosen here for comparison. The loadage and service life distance traveled proved to be very large influencing factors. As a result, our novel lightweight electric-assist bicycle was found to be effective for short-distance transport of a small amount of lightweight materials, as in a factory.
