Design and Fabrication of Solar Electric ScooterIJRES Journal
Electric motorcycles and scooters are plug-in electric vehicles with two or three wheels that can be recharged from any external source of electricity, and the electricity is stored in a rechargeable battery, which provides power to one or more electric motors to attain movement. Electric motorcycles, as differentiated from scooters, do not have a step-through frame. The electricity generated from an external source helps in acceleration of the motorcycle. The speed of this cycle is limited and the electricity is generated using a solar panel. The generated electricity is stored using a battery and the locomotion and movement of the vehicle is hence propelled using a motor. The cycle need not be continuously fed with solar energy in order to gain the capacity to run. It gets its energy from the batteries where the energy is stored. Conventionally, these types of vehicles are hard to use with the help of just mechanical energy. The energy we get from human effort. But when energy is converted using solar energy and a battery, it becomes more easy and helpful in the propulsion of the motorcycle. The motorcycle, not using an engine, becomes an effective way of road transport as it causes no pollution. It is eco-friendly and it definitely reduces human effort.

The Indian bicycle industry, the second largest in the world, produces around 10 to 14 mn units annually. China leads with a production of over 50 mn units. The total world market is estimated at close to 100 mn units. In value terms, the current market size is estimated at Rs. 22 bn and is growing at about 3.5% annually.The opening up of the economy in the wake of the overall liberalisation policies of the government, led to the spectre of cheap Chinese bikes entering into the Indian market. There was, however, no major threat emanating out of these imports according to the domestic cycle manufacturers. The entire market of bicycles can be divided into domestic and foreign markets.

Webinar: Can cycling and walking help release the longevity dividend?ILC- UK
If we are to maximise the longevity dividend, we all need to live healthier not just longer. Too many of us are being forced out of work too early due to poor health. And poor health results in lower consumer spending.
The Government’s recently published obesity policy paper recognised the importance of remaining active. And COVID-19 has inspired cities across the world to invest in cycle infrastructure. Places like Paris, Milan, and New York, historically hostile to cycling have created hundreds of miles of temporary infrastructure.
Yet in the UK, as we get older, we cycle less.
The picture with walking isn’t much better, In England, men aged between 30 and 69 actually walk slightly more as they age while women walk considerably less. As we hit our 70s there is a significant drop-off in miles walked by men and women.
But we know that whatever our age, active travel works. We also know that supporting people to get to and around our town centres is vital if we are to begin to see an economic rebound. New and improved E-bikes and Scooters could play their part.
We have a relatively short window to deliver policy changes which could better support more of us to cycle and walk.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

3. Urban transport
Actual situation in the EU.
At present, the European cities are living each day an accumulation of
excessive traffic and noise. Approximately one quarter of the population of the UE
live within 500 m from a road with more than three million vehicles annually.
Although the 50 % of the journeys by car doesn’t reach the 5 Km and the 30 %
don’t even reach 3 Km, the 75% of the mobility in the European cities are done by
car.
Other aspects that are being seriously harmed by the city traffic are the air quality
and the health. The traffic is the main source of many air pollutants such as carbon
monoxide and suspended particulates. In addition, the air pollution is the mainmonoxide and suspended particulates. In addition, the air pollution is the main
cause of environmental disease in Europe. Because of this air pollution, the citizens
have many possibilities to suffer some cardiovascular and respiratory problems.
The most important reasons of this air pollution are the traffic increase, also the
increase of cars with diesel engines that are more pollutant than cars with gasoline
engine. Another reason that explains the air pollution in the cities is the fact that
vehicles pollute more in urban environments because of the traffic.
Adding to the list of problems suffered by the European cities and therefore by the
citizens is the noise caused by the traffic. There are 210 million Europeans exposed
to noise levels potentially hazardous to health. This problem is more and more
increasing because of the traffic. According to a German study, 4000 heart attacks
annually are due to traffic noise (UBA, 2006). Other possible consequences are the
lack of sleep, discomfort, and mental effects.
Finally, and no less important, the climate change is quickly growing because of the
air pollution in the cities. Urban traffic accounts for more than 40% of CO2
emissions generated by vehicles and 10% of total CO2 emissions in the EU.
3
emissions generated by vehicles and 10% of total CO2 emissions in the EU.
To improve this situation, it is necessary to change the culture and the costumes for
urban mobility. Institutions and citizens must make an effort and try to solve this
problem as soon as possible. The following are some aims that would help to solve
the problem:
•Reconciling the economic development in cities with the quality of life and
environmental protection.
•Developing lifestyles less dependent on cars.
•Developing new clean an efficient ways of transport.
•Minimize the environmental and health damage.
•Reduce the energy use and the economic and social cost.
•Ensuring access for all the citizens.
4. The electric bicycle
The future of the urban transport.
The e-bike is a human electric hybrid vehicle. Basically, these bikes are for people
who want an alternative to a car, get exercise, go fast without increased effort, and
get you where you want to be. The e-bike is made not to leave the rider
completely idle but to assist in the movement over hills as well as flat ground.
Peddling on the part of the rider can be used both to move the bicycle and to
recharge the batteries. It’s an amazing, fast and efficient vehicle that respects the
environment. With this vehicle, it is possible to enjoy a leisurely and relaxing cruise
and arrive at destinations (such as work) at the same time.
Amazingly, the price of a e-bike is the same as a standard one. This means thatAmazingly, the price of a e-bike is the same as a standard one. This means that
acquiring this vehicle, the purchaser get the regular bike functions plus the
additional power from the battery to propel him faster than he could by himself
for a longer period of time. The electricity of the bike is not to increase the speed
or move without effort, it is to assist to the rider to ride at a regular safe speed on
or off road.
In addition, this vehicle is regarded by the same as a traditional bicycle by the law.
That is to say that riding an electric bicycle does not requires having a license to
the user.
The e-bikes are becoming the best way of transport in urban environments.
Bicycles are more agile and fast than cars because they are more maneuverable
and can easily bypass obstacles that would greatly slow down cars. Bicycles are
also easier to park because they are so portable. It is possible to park them almost
anywhere. To top it all off, most electric bikes have sufficient range to handle day-
to-day life in a city. Most traditional electric bikes still include the pedal assembly
as well as the electrical one, so you can simply turn off your throttle if you want to

as well as the electrical one, so you can simply turn off your throttle if you want to
ride for a while on your own power.
5. Can the electric bicycle solve the problem
of the urban traffic?
In this page I will compare the aims proposed before to solve the problem with the
features and benefits of the electric bicycle.
These were the aims proposed:
1. Reconciling the economic development in cities with the quality of life
and environmental protection.
2. Developing lifestyles less dependent on cars.2. Developing lifestyles less dependent on cars.
3. Developing new clean an efficient ways of transport.
4. Minimize the environmental and health damage.
5. Reduce the energy use and the economic and social cost.
6. Ensuring access for all the citizens.
We can see that introducing the use of the electric bike in the urban environment
of the Swedish cities is possible to achieve all these aims.
The electric bike does not harm the environment, minimize the energy usage
because it is a human electric hybrid vehicle. Riding a bike is healthy and fun at the
same time. Bikes are so much cheaper than cars, this means that is easier to
purchase and maintain an electric bike than a car. Bicycles are more agile and fast
than cars because they are more maneuverable and can easily bypass obstacles
that would greatly slow down cars. Bicycles are also easier to park because they are
so portable. It is possible to park them almost anywhere.
All of these features make the electric bicycle a very interesting vehicle that could
become the most important way of transport in the Swedish cities in a few years,
and later in all Europe.
5
and later in all Europe.
6. Brief
• The electric bike aspires to be the most seen vehicle in the Swedish cities, and later also in
the European cities.
• The main function of the electric bike is to reduce or even remove the fatigue from riding a
conventional bike. This objective must be met without changing the concept and the
message that the bike transmits to the people.
These are the features that the electric bike should have:
• The e-bike must have a Swedish look.
• The main target of this bike are workers. It is necessary to think about the profile and the
habits of this group of people.
• The electric bike is an eco-product and this feature should be visible to purchasers and
users.
• The maintenance and the starting of the electric bike should be fast and easy, reducing the
necessity of tools. The insertion and removing of the battery must be easy and fast. One of
the key considerations during the design of the bike will be the study of the possible places
to keep the battery and how to insert and extract the battery in the bike as well.
• The electric bike must have lights to see and to be seen in the darkness.
• The bike will contain as much standard parts as possible.
• The price of the e-bike should be between a bike and a motorcycle price.
6
• The price of the e-bike should be between a bike and a motorcycle price.
• The autonomy of the battery should be between 30 and 50 Km.
• The time necessary to charge de battery shouldn’t be more than 5 or 6 hours.
• The electric engine must work only if the user is pedaling.
• The e-bike should give to the user the possibility to choose the engine help level.
• The effort realized when riding the bike shouldn’t depend on the inclination of the
ground.
• The e-bike should be produced in Sweden.

Conclusion
Between all the kind of bicycles, the most popular are the city bikes because the
majority of the displacements occur within the cities. The lady city bike (kind of
bike 1,2,3) is the most popular bike in the Swedish cities. Studying the features of
all these kind of bicycles we realized that this three bikes are the best prepared for
this kind of displacement. This means that our bike should have similar technical
and ergonomic benefits to make it appropriate for the urban displacement.
20. Target: the Swedish working population
Swedish citizen profile:
• Age and gender: The average city worker is 35 years old.
• Marital status: About the 45 % (women and men) are married.
• Hour of working: 8 hours a day
• Education: They are educated people with a career or some other professional
degree.
• Occupation: business, education, engineering, …
• Income: around 28000 SEK per month• Income: around 28000 SEK per month
• Way of transport: At the moment, the 90 % of the population use the car to go to
work. The rest of the people use the public transport, the bike or walk.
Conclusions: For this group of people, the electric bike is the best way of transport.
With this vehicle they will be able to go faster and moreover, they will do some exercise
that will improve their health. Using the electric bike they won’t have to do any extra
effort and they will get to arrive at their jobs in a shorter period of time.
Moreover, they will spend less money and they will help to save the environment.
We are convinced that they will love this fantastic vehicle.

Concept 4
This model is basically the initial idea that was developed in the first creative
session. In this design, the battery is located inside two special profiles that join
the front and the back part of the bicycle.
It is characterized by the use of the straight line. Its esthetic and style is totally
functional.

Concept 5
This concept is quite similar to the first one, but we have changed the style of the
top stay of the frame and the special profiles. Now, the top stay is completely
curved and is joined to the seat tube in the same point as the top special profile.
The special profiles have changed from a continuous and smooth shape to a new
shape with more stress and personality.

35. Component description
Frame
The frame is the most important component in our electric bicycle. Its innovative
geometry is different from the actual bicycle frames because we locate the battery
inside it, just between the seat and the fork tube, thus avoiding the need for extra
support to accommodate the battery, such as e-bicycles today do.
The hole which houses the battery is formed by a cross cut that passes through
the Top and Down Tubes. During the development of the frame, we realized that this
hole could make the frame weaker. To solve this strength problem, we designed a
special profile (number of the picture) reinforced with two walls that divided it into
three sections. This special profile allow us to make the hole of the battery assuring thethree sections. This special profile allow us to make the hole of the battery assuring the
strength of the bike.
To develop this frame we also considered the question of style. We wanted this
bike to be Swedish-styled, innovate and unique. This aim was achieved with the
combination of two kind of profiles (circular and elliptic), that makes the frame more
aerodynamic and esthetic. Also a noteworthy point is the special use of the curve that
makes the frame more continuous and uniform.

Fork
The fork is the component that joins the front wheel and the handlebar with the
rest of the bicycle. For the design of this component the aim was to maintain the main
character and aesthetics achieved with the frame. We want to emphasize the use of the
curve and the combination of circular and elliptical profiles as we did before with the
frame.
Putting the fork and the frame together, it can be seen that the two form a
uniform set, with the same esthetic design and style.
Technically, as the frame, the fork is manufactured with aluminum profile, colored
with Pantone Black and finished by anodizing.with Pantone Black and finished by anodizing.

Battery
The kind of battery selected for this bike is a lithium-ion battery. We changed the
dimensions and shape of the original one to make it easier to carry, insert/extract and
recharge.
This battery has a saddle that can be hidden inside it to make the bicycle more
esthetic.
Because it is not a standard battery, it is necessary to find a Li-ion Battery
manufacturer that help us to find the way to be able to manufacture this battery
design.
The next pictures show the main dimensions and the appearance of our battery.The next pictures show the main dimensions and the appearance of our battery.16825

Battery Support
This component serves to attach the battery to the bike and to connect the
battery to the electrical circuit.
With this battery support, the process of connecting the battery to the bike is
considerably reduced because the user doesn’t have to connect cables. All the
connectors between the battery and the bike are located in this component.
As the pictures below show, the battery support is assembled to the bike just with two
screws .

Handlebar
The handlebar is made by steel circular profile with a 18 mm diameter. To make it more
ergonomic and to continue with the style and appearance of the bicycle we decided to
bend the extremes like the pictures below show.
The innovative support of the handlebar has been also bent in such a way to give the
bicycle a more unique look.

43. Cables distribution
Thank to the new location of the battery, all the connections between the battery
and the rest of the electric circuit are placed inside the frame. The only cable that will
be seen is the one that goes from the engine to the battery support. As the picture
bellow shows, this cable goes out from the fork and gets into the frame through the
extreme of the Down Tube.
With regards to the mechanical cables, there are only two cables that will be seen.
One of these cables belong to the gear control and the other one belongs to the front
brake. As the picture below shows, the cable of the gear control goes into the framebrake. As the picture below shows, the cable of the gear control goes into the frame
through the extreme of the Down Tube, and the cable of the front brake goes out from
the fork and is connected directly to the brake lever.

50. Looking for a manufacturer
Taking a look at the brief (page 3) and analyzing the situation of the market, we conclude that
VOLVO would be interested in making our bike. These are some of the reasons that make us to
conclude this:
• VOLVO is a Swedish brand that manufactures vehicles.
• As we said in the brief, our bike must have a Swedish style and philosophy, like the
VOLVO´s products have.
• This brand could easily manufacture the bike because they have the technology and
resources to make it possible.
• VOLVO is a brand interested in eco friendly vehicles and they are already manufacturing• VOLVO is a brand interested in eco friendly vehicles and they are already manufacturing
some eco friendly cars, so producing this bike they will be seen as a brand that respect the
environment, improving their projected image to the customers.
The brand will be shown in the front of the bicycle as the picture below shows.
50
51. Volvo has recently developed eco friendly car models supported by the
logo “Drive”. These cars achieve emissions figures as low as 104g/km and
72mpg.
We have redesigned this logotype (“Drive”) that are used with the eco-
friendly cars to be used on our electric bicycle. The new logo uses the
same typography and colors as the original, but uses the word “Ride”
instead of the word “Drive”. This logo will be seen in the front face of the
battery as the picture below shows.
