Abstract: The Era of the eco-friendly technologies is emerging rapidly; bicycles are the most dependent modes of transportation. The environmental factors and the increase in fuel price make it clear that it is far better to use a bicycle over a motor vehicle for traveling. This project 'Design and implementation of Electric Bicycle with battery monitoring system and speed control mechanism, is designed to provide two modes of travel, such as a power- on-demand mode for long distances and pedaling mode for short distances. This electric bicycle is provided with ease to switch between these two modes of operation. The electric vehicle depends on the battery for energy. Provision for monitoring the state of charge of the battery using lot techniques is provided in the project. The speed controlling mechanism enables the user to ride the electric bicycle in different ranges of speed IOT based speed monitoring system is provided. The monitored values of battery state of charge and the speed are displayed so that the rider gets the information about the status of the battery and the speed. Each circuit is designed separately and assembled to form an electric bicycle which can make the long distance cycling easier with many user-friendly features.

Keywords: Electric bicycle, Speed Controlling, Speed Monitoring, Battery Monitoring.
