Electric powered two-wheelers (e-bikes): a welcome game-changer? - Chris Cherry - University of Tennessee, Knoxville - Transforming Transportation 2015
Chris Cherry presented on the future of ebikes at the Transforming Transformation 2015.
Transforming Transportation 2015: Smart Cities for Shared Prosperity is the annual conference co-organized by the World Resources Institute and the World Bank.
We started with various kind of frictional forces which are projected to bicycle during the run. Then after we calculate approx motor power t which needed to drive the bicycle. We used BLDC motor as a hub drive and connect it in the front wheel of the bicycle. We use lithium-ion battery cells and by connecting them in series-parallel, we made a 36V, 13.2 Ah battery pack. We also connect BMS(Battery Management System) which protects the battery pack from over-charging and over-discharging kind of faults. Top speed of the bicycle is 35kmph and the distance traveled on a single charge is up to 35 to 40km.
I have been working independently in manufacturing electric vehicles from quite a time, the market is still evolving in India for electric vehicles with an aim to reach a mark of around 90% electric vehicles running on road in proportion to total vehicles. A lot of advancements have been made regarding the same and i have compiled some of my observations in this presentation. Hope you like it and do discuss what you feel about the new evolving market in India.
This is a business plan for the newly developed electric motorcycle prototype. The PPT gives details about the idea, the motorcycle, the making, specs, advantages etc.
Transport Thursday is an initiative of the TU Delft Transport Institute. Satish Beella gave a presentation on the "Present and Future of the Electric Bicycle". Enjoy!

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.
Electric cars are automobiles, which are powered by the electric engine and electric energy. The development of the electric vehicles is a very perspective and important process. Scientists and engineers managed to create electric engines which are no less effective than the ordinary engines used today. It is obvious that electric cars are more ecologically safe and require less energy for work. EVs provide fast acceleration by delivering power instantly to the wheels by providing high torque at low speeds; they give a feel of smooth and quick responsiveness (Technology).
All types of engine-driven vehicles from automobiles, airplanes, aircraft carriers, and agricultural equipment to Zambonis may have electric motors to perform a variety of functions. In electric vehicles, diesel-electric vehicles, and hybrid vehicles, electric motors are used to propel the vehicle. The motor controllers in-vehicle applications are integrated into the vehicle.
The machine is very much advance and simple to construct. The working of machine is easy and eco friendly . Its is the most economical vehicle as there is no fuel consumption. The cost of all the component is less and the component should be easily available in the market.so presently it is common to use in developing countries.

6.design fabrication and analysis of tri wheeled electric vehicle (2)EditorJST
In daily life we can observe the difficulties of carrying the patients, old people, physically handicapped in public places like airports, railway stations, bus stands, hospitals, college campuses etc. To aid such people we prepared an electric tri-car to ease the task of carrying them. Moreover, it is a multipurpose vehicle to carry pilgrims in pilgrim places, to carry inspection teams in industries, estates or campuses etc. The seating arrangement of this tri-car is such a way that the disabled can easily get into the vehicle and also get down. This tri-car is designed and analyzed with the help of the soft ware called PROE. Then analysis is done in Statistical and Modal Analysis. We modeled and fabricated a tri-car into a three wheeled electric powered vehicle with three seats and can accommodate two pillions and a driver. We designed the vehicle to be propelled by an electric hub motor mounted in the front wheel and powered by 48V Lithium-ion battery.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

7. E-bike riders as future car owners
Kunming: ~40% of e-bike riders have car in household, now more
than bicycles and relatively large fraction plan to purchase
In Kunming: Household vehicle ownership and purchase plans.
8. E-bike riders as future car owners
Is Kunming representative?
We conducted a national telephone survey and found similar
results: HH car ownership (19-40%), purchase plans (8-30%).
Hierarchical logit for car purchase: HH variables matter most,
some city/regional-level data.
9. So what’s not to love?
E-bikes have an image problem
11. E-bikes unsafe or vulnerable?
Recent studies on e-bikes find:
– e-bike riders behave poorly
– e-bike fatalities up a little less than e-bike growth
12. What about the batteries?
Battery production loss rates
hover around 20-30% of the
battery weight…
Multiplied by tens of millions of
batteries a year
15. Bikesharing as externality control
Bikeshare/Scooter share
– Beijing stated preference mode switch model of e-
bike sharing vs. bicycle sharing
– E-bike: bad air days, hot days, longer trips, compete
with transit
– E-bikes pull from “sheltered” modes
– Young- and middle-aged male respondents more
likely to use e-bikes and bikeshare in general
