Electrically Assisted Bicycle for Urban Micro-Mobility Solution

Abstract

The present work intends to build and study a prototype of an electrically assisted cycle for urban micro-mobility solution. The bi-cycle has been redesigned and modified from an urban commuter diamond frame design bi-cycle. As because the frame is solely responsible for the load distribution [1]. Electric batteries acquire enough space and also changes the vehicle dynamics of the bi-cycle. Diamond frame allow designers to easily integrates batteries [2]. The components of bicycles and electrical bicycles were studied and compared, this way we could do a correct and wise choice of components to be used in the project. Since the market already presents several different solutions in terms of this concept, it was made a study regarding some of the market available models, considering its advantages and disadvantages. The project focused on improving market existing bi-cycle more ergonomically in affordable cost keeping the facility as much as possible. Also for future mass production, components are sourced from domestic market for existing supply chain. The project has been built for single person ride so that required parameters were calculated as per single rider weight. Later the prototype has been built with the available electric conversion kit in the domestic market. The entire frame has been designed using CAD software. Modified part was entirely built in local workshop such as seat and chain stay. The prototype has been tested physically and the result of the physical model has been analyzed and discussed. Also future scope of work has been discussed with some of this projects limitations.
