As we all know, fuel prices, especially petrol, are rising steadily day by day. Again,
the pollution due to vehicles in metro cities & urban areas is increasing continuously.
To overcome these problems, an effort is being made to search for some other alternative
sources of energy for the vehicles.

Again, it is also not affordable to purchase vehicles (mopeds, scooters or motorcycles)
for all the classes of society. Keeping this in mind, a search for some way to cater these
economically poor people as well as to provide a solution for the environmental pollution
was in progress.

The solar assisted bicycle developed is driven by a DC motor fitted in front or rear axle
housing & operated by solar energy. The solar panels mounted on the carriage will charge
the battery & which in turn drive the hub motor. When the bicycle is idle, the solar panel
will charge the battery.

This arrangement will replace the petrol engine, the gear box & the fuel tank in case of
a two wheeler or a chain sprocket, chain & gear shifting arrangement of a conventional
bicycle being used by most common man. [9]

As a part of dissertation work, the solar assisted bicycle is fitted with a dc hub motor
on the front axle of a bicycle with power rating of 250W and with a travelling speed of
around 25–30 kmph. It is provided with a pair of lead acid batteries of 35 Ah each, a
photovoltaic solar panel with capacity of 20 watt, a voltage regulator of 24v 10 Amp,
accelerator and motor controller of 24v 25Amp.

There is also a provision for charging the battery with 220–240V AC wall outlet supply,
in case of poor solar supply due to cloudy weather.

As what had been mentioned earlier, there are several types of bicycle that can be
categorized: paddle bicycle, motorized bicycle, and electric bicycle. The weakness of
the bicycle makes people not like to use bicycles.

First, paddle bicycles need a lot of energy to paddle the bicycle. The user will surely
be tired after using the bicycle. This will not be suitable for students to use to go to
the class because they will be tired when they are in the class and will lose their
concentration while hearing the lecture.

Next, motorize a bicycle that uses fuel as its prime mover. The bicycle uses fuel that is
costly. As a student, their allowance is limited and only can be used for their study
material and for their food to survive at the campus.

Besides that, motorized bicycles will make pollution that can be very bad for our
environment especially in this period that global warming happens to the earth.

Lastly, electric bicycles that are generated by batteries can only be sufficient for
about an hour. The user needs to find power supply to
