2. What is E-KIT
The E-kit is a modified version of THE
COPENHAGEN WHEEL in which we have tried to
eliminate all its limitations.
E-kit is a kit which will transform any random
cycle into an electrified vehicle while keeping it
cheap and simple.
We are actually dealing with design parameters of
making this installation faster, sturdy and efficient.
The mechanism is basically a wheel which can be
affixed to any bicycle at any moment on users
demand, quickly.
3. Need of E-KIT
It can easily transform any common man cycle into an
electrically driven vehicle very easily.
Controllable assistance that can help the unfits start cycling
regularly.
Make it easer to travel further, regularly and carry more.
Gives extra help going up hills and cycling into headwinds.
Accelerating to cruising speed in a fraction of the time/ effort.
Costs a fraction of the price to buy and run compared to
bikes.

concerned about traffic.
5. What is Copenhagen Wheel?
The Copenhagen wheel is a
bicycle wheel that can easily
retrofitted into any ordinary
bike.
It’s sleek red hub not only
contains a motor, batteries
and an internal gear system,
but also includes
environmental and location
sensors which are powered
by the batteries in the wheel
and provide data for cycle
related mobile application.
7. Working principle
The Copenhagen Wheel uses a technology
similar to The KERS (Kinetic Energy Recovery
System), which has revolutionized Formula One
racing over the past couple of years.
When you brake, your kinetic energy is
recuperated by the electric motor and then stored
by batteries within the wheel.
It also occurs in exercise mode - where riders are
working a g a ins t the motor, thus giving themselves
a workout and in turn recharging the batteries in
the hub.
8. G o a l o f The Pro je c t
To reduce the rotating mass from the hub of the
Copenhagen wheel.
All components should be placed in a single hub.
The wheel must be easily retrofittable into any standard
bicycle.
The bike must harvest energy through braking and
pedaling by choosing one of three modes:-
i. off
ii. Motor Assist
iii. Pedal Assist (Regeneration/exercise mode)
The weight should be no more than a ‘heavy bike’ when
fitted into a regular bike.
9. Advantages
Environment friendly.
Easily adjustable to any bike.
Doesn’t create extra load on ride.
Can be controlled by mobile phone.
Ensures rider’s health safety.
Encourages people to use cycle as a transport.
10. Disadvantages
Have to use a mobile phone to get full
functionality.
Not available worldwide, specially in third
world country like us.
Not cheap for people having low income.
Not good for too much hilly areas.
12. Methodology
1. CAD design-we will try to give the local
population an alternative to the mainstream
cycles. This is to be done by designing from
scratch the kit on CAD software.
2. Prototype analysis-a prototype will be built
which will basically transform the ‘hero’ into a
electrified vehicle while keeping it cheap and
simple.
13. Requirements
Motor Type: 24 volt, 400 watt continuous / 800
watt peak power
Battery Type: Dual 12 volt, 10 amp/hour,
rechargeable battery pack
Recharge Time: 3-7 hrs (with outlet charger)
Top Speed: 15 MPH
14. Future prospects
Vehicle of future - Leading automobile
companies are keeping their eyes on it.
Versatile application - Can be install in bicycle
as well as in rickshaw and in other vehicles.
In mass production cost of manufacturing will
drastically reduce.
15. Ford e-bike Ford unveiled its new e-bike as a study on urban
mobility solutions.
16. The new Smart e-bike It will sell for under €2,900 in
Europe.
17. Conclusion
The Copenhagen Wheel project began by
asking the question: how can we improve the
cycling experience in order to encourage more
people to ride bikes.
The same spirit rides in our hearts and surely
it will fulfill the goal by attracting more people
for safe cycling.
