Abstract: The Electric Bicycle System is a systems project that incorporates three different parts like 12 volt battery, alternator, DC motor. DC motor which is used to power an electric hub motor runs a bicycle. The purpose of the project is to show that it is possible and relatively simple, to build an electric bicycle by oneself. This project can be broken down into three separate categories: the lithium-ion battery, the alternator, the motor, and the motor controller. Each of these will be built upon and improved further by future students, one category at a time. The hope is that this design can become very efficient, cost-effective, and one day mass-produced, especially in developing countries where automotive transportation is an impossibility.
