Compared to electric automobile, electric motorcycle is small and efficient vehicle for bringing single person or two people. However, to use electric motorcycle, there are few problems ; running distance of the motorcycle is not very long, its output is not very powerful. In this study, in order to extend running distance, we applied solar cells on the rooftop of the motorcycle. Solar cells are connected to the lead-acid storage battery. Running experiment on the flat ground was done at the speed of 20 km/h, under the fine weather in winter. As a result, the motorcycle with solar cells ran 42.8km. Running distance was achieved 27% longer than that of the motorcycle without solar cells. Moreover, we designed and made a prototype of the regeneration brake system for the motorcycle with EDLC. The electric power collected from the motor at the braking time was able to be stored electricity into EDLC, and the load of the lead-acid storage battery at the acceleration time was able to be reduced re-utilizing the electric power.
