However, it is expensive for such systems to be built. But the population living in metropolis area are increasing. Hence the need for electric energy is increasing too. Therefore, small portable greener electricity power generating systems are necessary for supplying high populated area and the area lacking infrastructure. The electric generating device, a small electric generator built on a man powered bicycle, is designed according to the green environment protection codes. However, recent reports indicate that the deficient capacity of batteries and slow charging rate are encountered. An electric generator attached on a general man powered bicycle is proposed in this study. While the bicycle is running, the electric generator generates electricity and charges the battery. That is, the man powered energy is converted to electric energy. In the need of a electrical assisted vehicle, this study is focused on the properties of the output of the generator. Furthermore, an optimal gear ratio and a better control unit are to be found. The output voltage and current are measured in different speeds and loadings. With the study, an efficient power supply system is to be found.
