ABSTRACT
This paper presents the development of an associate degree “Electric Bicycle System” with an
innovative approach. An electric motor bicycle is such type of modified bicycle which is
eligible for the input and output of power in integrated within a single bicycle. It is also known
as an e-bike or booster bike, is a bicycle with an integrated electric motor which can be used
for propulsion. The first electric motor bicycle was introduced in the late 19th Century. An
electric motor bicycle is widely chosen than the conventional bicycle, so that less human effort
is given. It is more adventurous where human can’t be go by a conventional bicycle like hilly
and mountainous areas. An e-bike do not pollute the environment, as it runs on the complete
green energy. It is completely eco-friendly. It is used for long distances and used by the peoples
who is having difficulties to pedal the mechanical bicycle. It is also great for the ill peoples, so
that they can roam around easily and can go to the places. Pedaling an e-bike is easier due to
its electric motor which gives an e-bike the speed of 25 - 32 Km/hr. The Higher motor gives
up to the speed of 44Km/hr. It comes cheap and easy to maintain. An e-bike owner can go with
it anywhere, it takes you out fast from the traffic and even from the busiest road and streets. It
does not create sound, battery can be charge easily and fast. It replaces the more uses of motor
vehicles which produces smoke and sound as its exhaust. Some of the countries we have to be
above the age limit to ride an e-bike, like UK dictates a minimum rider age of 14 for anyone
using an electric bicycle.
It is costlier than the conventional bicycle, sometimes it costs like a motorbike. When the
battery drains out or at the end pedaling is difficult at that time, the engine, battery pack, and
associated controls all add significantly to the weight of an electric bike. That's not a problem
so long as the battery is charged up and ready to help you pedal, but if all you're dealing with

Chapter - 1 INTRODUCTION
An electric bicycle, also known as an e-bike or booster bike, is a bicycle with an integrated
electric motor which can be used for propulsion. There is a great variety of electronic bikes
available worldwide, from electronic bikes that only have a small motor to assist the rider's
pedal power (i.e., pedals) to somewhat more powerful electronic bikes which tend closer to
mope style functionality: all, however, retain the ability to be pedaled by the rider and are
therefore not electric motorcycles. E bikes use rechargeable batteries and the lighter varieties
can travel up to 25 to 32 km/h (16 to 20 mph), depending on the laws of the country in which
they are sold, while the more high powered varieties can often do in excess of 45 km/h (28
mph). In some markets, such as Germany, they are gaining in popularity and taking some
market share away from conventional bicycles, while in others, such as China, they are
replacing fossil fuel powered mopeds and small motorcycles.
Depending on local laws, many e bikes (e.g., pedals) are legally classified as bicycles rather
than mopeds or motorcycles, so they are not subject to the more stringent laws regarding their
certification and operation, unlike the more powerful two wheelers which are often classed as
electric motorcycles. E bikes can also be defined separately and treated as a specific vehicle
type in many areas of legal jurisdiction.

The electrical bicycle offers a cleaner various to travel short-to-moderate distances instead of
driving a patrol/diesel-powered automotive. The value of crude has multiplied consider over
the past few years and it looks to be no turning back. The electrical bicycle could be a project
which will promote each cleaner technology also as a lesser dependence on oil. It’ll run on
clean power with the flexibility to recharge the battery three separate ways: through the 120V
AC wall supply, by generating power through the pedals of the bicycle, dynamo and by solar-
cell generative power. Fashionable electrical bicycles integrate many inventions from
technology and style, significantly within the past year.

Chapter - 2 HISTORY
2.1 Previous Electric Bicycle
The idea of a motorized bicycle isn't a recent conception and has been around for over a century.
Until 1895, the electrical bicycle created its place in history. That year, Ogden Bolton was
granted U.S. Patent 552,271 for a powered bicycle with a six-pole brush and commentator DC
hub motor mounted within the rear wheel. The bike itself had no gears and therefore the motor
may draw up to 100A with a 10V battery. Since then, the conception of the electrical bike
became possible and sensible. Because the years progress, additional and additional electrical
bikes were made with varied driving mechanisms.
The electric bike may seem like a new technology, but in fact, it is nearly 120 years old. Some
patents for the electric bike were publish in the late 1800s, dating this technology back further
than many assume. The technological improvements on the electric bicycle have been vast,
making it an extremely interesting piece of transportation history. Around 1870, two inventors
created what is believed to be a predecessor for the electric bike. This motorized bicycle used
a steam engine and an internal combustion engine.
At the end of 1895, one of the first patents for an electric bike was issued to Ogden Bolton Jr.
His patent was mostly centered on an improvement for the bike, rather than a unique invention,
so it is not believed to be his original idea. Shortly after, Hosea W. Libbey invented an e - bike
that used two motors and two batteries. Nearly 50 years later, Jesse D. Tucker got a patent for
a motor that used internal gearing and offered the ability to freewheel. This mean the rider
could choose whether or not to use the pedals in combination with the electric motor.
2.2 Modern Electric Bicycle
The history of electric bikes may date over a hundred years, but we have not given up on the
technology. Inventors continue to develop new patents for the electric bike, improving on the
original idea more and more. There are millions of electric bicycles sold in the USA and the
numbers only continue to grow. More consumers are starting to realize the great benefits of
electric bike and the ease of transport that it brings. With energy saving abilities, the e – bike

will continue to grow in popularity over the years. The latest inventions that have improved the
technology include the following equipment.
Torque sensors
Power controls
Advanced batteries
Better hub motors
2.3 Modifications
The electric motor used in this e – bike works as both the medium for charging the battery and
run the bicycle during the required time. It is well known that the electric motor functions as
both the equipment as follows:-
Converting the mechanical energy into electric energy.
Converting the electric energy into mechanical energy.
When the rider runs this bicycle with pedal, the electric motor will charge the battery as it is
connected to the tire of the bicycle by converting the mechanical energy into electric energy.
Similarly when the rider feels tired, he/she can enjoy the ride by using electric energy as the
Page | 7
battery is charged earlier. There is a switch for this purpose to connect it to the proper situation
as the single electric motor is functioning in dual ways.
Similarly the high ratio gearing is used in this bicycle for racing purpose. It benefits the rider
in two ways. With less effort the amount of battery charged is more which will enhance the
rider to enjoy the ride for long distance without pedaling by riding the bicycle with pedal for
short distance. In the same way the rider can enjoy the fast drive by applying less effort.
Therefore this bicycle is full of comfort and joy in affordable price.
The tire used in this bicycle is tube less tire. Therefore there is no risk of puncture in rocky and
thorny areas. In the same way it also benefits in summer season where the temperature reaches
quite high. The tire with tube is generally blasted after long drive in summer season in the
country like India as the temperature becomes very high during May and June. In this way this
bicycle is fully adventurous by all point of view.

Chapter – 3 COMPONENTS DESIGN
3.1 Designing Software
All the components of this electric bicycle is designed in “CATIA V5 R21” which is developed
by Dassault Systems. This designing software is basically made for surface modeling which
incorporates CAD, CAM and CAE. It has module for working from drafting module to the
analyzing module. Since the analyzing module is not quite effective in this software, a
professional analyzing software is used to analyze the stress and strain. In most cases, Ansys
is preferred for this purpose.
3.2 Introduction to Software
CATIA stands for “Computer Aided Three – dimensional Interactive Application.” It is
developed by the German company, The Dassault Systems. It is Microsoft windows based
application and highly user friendly. All the commands are operated by the single click of
mouse. Therefore there is no need of high professional course of it as all the modules have
guidelines for it and the online help is available from the official website of the Dassault
Systems.
The Version 5 Part Design application makes it possible to design precise 3D mechanical parts
with an intuitive and flexible user interface, from sketching in an assembly context to iterative
detailed design. Version 5 Part Design application will enable you to accommodate design
requirements for parts of various complexities, from simple to advance.
This application, which combines the power of feature-based design with the flexibility of a
Boolean approach, offers a highly productive and intuitive design environment with multiple
design methodologies, such as post-design and local 3D parameterization.
As a scalable product, Part Design can be used in cooperation with other current or future
companion products such as Assembly Design and Generative Drafting. The widest application
portfolio in the industry is also accessible through interoperability with CATIA Solutions
Version 4 to enable support of the full product development process from initial concept to
