Design And Construction Of An Electric Bicycle

The design and construction of an electric bicycle involve integrating various components to create a reliable and efficient mode of transportation. First, the frame, typically made of lightweight materials such as aluminum or carbon fiber, is engineered to support the weight of the rider and the electric components while ensuring stability and maneuverability. The electric motor, often mounted in the hub of the wheel or integrated into the crankset, provides propulsion, with its power output determined by factors like wattage and voltage. A rechargeable battery pack, usually lithium-ion, stores the energy needed to power the motor and is securely mounted to the frame. The electrical system, including controllers and sensors, regulates the flow of power from the battery to the motor, ensuring smooth acceleration and responsive braking. Additional features such as regenerative braking, which recaptures energy during deceleration, and onboard displays for monitoring speed and battery life, enhance the functionality and user experience of the electric bicycle. Finally, considerations for ergonomics, aesthetics, and safety are incorporated into the design to create a cohesive and appealing product that meets the needs of the modern commuter while promoting sustainability and reducing reliance on fossil fuels.

ABSTRACT

The main aim of this review paper is to present the idea of harnessing the various energy and use it in today’s existence of human life .Now-a-days there are so many vehicles on road, conventional bicycle which is pedal operated requires much human effort to operate it. Taking this into consideration it is our small step towards reducing the use of more human strength and attract the eye of people towards its alternatives i.e. Electric bicycle. So we intend to design a cycle which would run on an alternative source and also reducing human efforts called as Battery Operated Cycle. In this paper we design an alternative mode of transport for betterment of social and environment.

1.0 INTRODUCTION

1.1 BACKGROUND OF THE PROJECT

The electric bicycle is an electrical-assisted device that is designed to deliver the electromagnetic momentums to a present bicycle therefore relieving the user of producing the energy essential to run the bicycle. It contains a strong motor and enough battery power that just needs charging to help in hill climbing, generate greater motoring speeds and provide completely free electric transportation. Electric vehicles price more and perform poorer than their gasoline counterparts. The aim is that mainly because gasoline cars have promoted from a century of intensive development; electric cars have been virtually overlooked for several years. Even today, gasoline cars profit from billions of dollars of research every year while electric vehicles receive a small fraction of that quantity of money. The primary principle for the Universities‟ support of the electric- powered over the petrol powered has been towards improving air quality, though air quality alone is not a satisfactory justification to mandate electric bicycles. The single biggest advantage of electric bicycle is that it is cost operative as it mainly only entails building cost as running cost would only require the charging of the battery. An Electric bicycle would, however offer other solid benefits that are overlooked by the marketplace. These include the intense reduction in oil consumption that its widespread use would bring about. Much less oil would be needed because only a tiny proportion of electricity is generated from oil. The further major non-market benefit would be lower greenhouse gas emissions.

1.2 PROBLEM STATEMENT

In today’s modernized world travelling is very essential for human beings in order to protract in this world. And to do so his travelling should be done in minimum possible way. This project details about the electric bicycle which runs on the battery thereby providing voltage to the motor. This project compromises with design and fabrication of Electric bicycle which makes use of Electric energy as the primary source. The electrical power generated which is used to run the bicycle can give better movement compared to conventional vehicle.

1.3 AIM OF THE PROJECT

The main aim of this study is to build a bicycle which runs on the battery thereby providing voltage to the motor that moves the wheel using sprocket and chain.

1.4 SIGNIFICANCE OF THE PROJECT

E-bikes use rechargeable batteries that can travel up to 25 to 45 km/h, much faster than most people would cycle, getting you to your destination quicker and in better shape. In a nutshell they offer low cost, energy efficient, and emission-free transportation which also has physical and health benefits.

1.5 LIMITATION OF THE PROJECT

The autonomy of the lithium batteries (lead batteries are hardly used any longer because of their weight and contamination) is around 35 to 60 km, although this can vary depending on how the motor is used, rider weight, etc. Some batteries can last for up to 140 km.

1.6 SCOPE OF THE PROJECT

The system which we innovated is the electric bicycle. This project has various benefits both to the members of the team and also external benefits thereby making awareness of using alternative modes of transport. The Electric Bike which works on the battery that is powered by the motor is the general mode of transport for a local trip. The Electric bicycle which will be running on battery, the power is supplied by the motor, thereby supplying this power to drive the other gear components.

1.7 PURPOSE OF THE PROJECT

The main purpose of using this electric bicycle is that it is user friendly, economical and relatively cheap. The efficiency of this system undeniable compared to conventional modes of transport. Electric bicycle comprises the features like high mobility efficiency, compact, electrically powered, comfortable riding experience, light weight vehicle.

1.8 RESEARCH METHODOLOGY

In the course of carrying this study, numerous sources were used which most of them are by visiting libraries, consulting journal and news papers and online research which Google was the major source that was used.

1.9 PROJECT ORGANIZATION

The work is organized as follows: chapter one discuses the introductory part of the work, chapter two presents the literature review of the study, chapter three describes the methods applied, chapter four discusses the results of the work, chapter five summarizes the research outcomes and the recommendations.
