3. Introduction: This talk will begin by explaining the concept
,the development of bicycle to be result of self charged moving
vehicle .
4. Working principle It is based upon the principle of
mechanical energy converted into electrical energy by frictional
method . The Rotary motion is converted into friction in between
coil and magnets.
5. Competencies:TECHNICAL KNOWLEDGE, DESIGN.

9. BICYCLE
10. GEAR MECHANISM
11. Basically gears are made of two circular discs of different
sizes. Both of them are cut in the end to form numerous teeth like
structures. When the smaller disc rotates, the tooth touches teeths
the bigger disc making both to rotate. The smaller disc has to
rotate many times to make the bigger disc rotate once. For example
say the smaller disc has to rotate 30 times to make the bigger disc
rotate 1 time the ratio is 30:1. This is known as Gear ratio. The
speed of the bicycle depends mainly on this gear ratio.
12. Alternator alternator is an electrical generator that
converts mechanical energy to electrical energy in the form of
alternating current.
13. the alternator is connected to the front tire and generate
the power and stored in to the battery
14. Control systems Handle Brake system
15. Control system The control systems are one of the most
important component of the vehicle . The controls consistof handle
system and brake system. The function of the handle system is to
change the directionof vehicle . The function of the brake system
is to slow down or stop the running vehicle.
16. AUXILIARIES Start circuit Horn circuit Indicator circuit
Light circuit charging circuits The above circuits perform their
functions with its ancillary devices.
17. STEP UP TRANSFORMER
18. Step up transformer On a step-up transformer there are more
turns on the secondary coil than the primary coil. The induced
voltage across the secondary coil is greater than the applied
voltage across the primary coil or in other words the voltage has
been stepped-u p A step down transformer has less turns on the
secondary coil that the primary coil. The induced voltage across
the secondary coil is less the applied voltage across the primary
coil or in other words the voltage is stepped-down.
19. BATTERIES
20. Battery Battery is a device which converts chemical energy
in to electrical energy It is made up of no of cells
21. Battery is placed on the cycle At first the battery is
charged by the power source This battery is connected to the dc
brushless motor
22. Charging of batteries The charged is connected to an
external electrical energy source. The source should be able to
supply dc to the battery put to charging. When the electrical
current passes through the battery, the chemical reactions which
takes place inside the battery would convert the electrical energy
into chemical energy.
23. ACCESORIES Speed meter Volt meter
24. How does it work? It consists of several parts: cycling
system (part of the traditional bicycle), battery, controller
(sends power to the motor with the help of a twisting mechanism),
electric motor . The motor is supplied with power from the battery,
which is rechargeable by the help of alternator (which is used in
the car to produce electricity ). Although a solar panel can also
be used. Certain modern motors can be charged while riding down
hill. When the motor receive power from battery through the twister
it starts the motion which helps to vehicle to run on road for
motion for long distances. When the rider stops pedal it doesnt
rotate because the sprockets is rotate same direction of vehicle
movement.
25. How to stop the vehicle To stop the vehicle we need to
release the twister in order to stop the motion of the motor then
apply the brake for stop.
26. Procedure It is utilized the stored power to push the
vehicle. The powered motor is located at rear side and used to move
the bicycle. Alternator is fixed at front side and generate the
power, when the front wheel is rotated. These alternator are
utilized to produce the power and stored the power in battery .This
battery will store the energy and supply power to the rear motor .
Here we use a device called as step up transformer for increase
rate of flow of power to the battery as per battery requirement to
charge, the voltage in battery.
27. The vehicle contains two gears with their respective
positions ,In that one gear is used for peddling and another gear
is used for dc brushless motor. These two gears are interlinked
with chain by method of mechanism. When the vehicle is switch on
then the process of mechanism is directed towards vehicle start
moving by accelerator. We can used control system as our
requirement. We can also providing auxiliaries for betterment. The
speed of the vehicle is shown in speedometer. The power is produced
can be shown in the battery
28. Merits: It is a self charging vehicle .It does not require
fuel ,current repetitively. Sitting capacity is two . Performance
of self charging vehicle is 100 KMPH. There is no harm full to
nature . It does not causes air pollution. Suitable for middle
class. Performance of the vehicle is good.
29. Conclusion: We are conclude this project as much as our
knowledge and possibilities.
