What the Expert Says:

Hi -
don't know what class 10 means, 10th grade? Do all of the themes have to be addressed, or only one of those? It would help if your question was clearer. Do you have any interests among the sub-themes?

How to Generate Electricity With a Bicycle

1
Position the bike where you want and remove the front tire. Keep the bike stable and safe to sit on by placing the bike frame between cylinder blocks. Make certain the back tire is elevated enough so it will spin freely.

2
Remove the tire inner tube from the back wheel. Wrap the belt around the wheel and attach it to a pulley. A size B V-belt and 2.5i pulley will work with a 10-speed bike (See References).


3
Hook the pulley to the generator. The bike should now be able to start the generator.

4
Connect the generator to the diode using copper wire, making certain the positive and negative leads are attached to the appropriate terminals. The generator and diode both have positive and negative terminals.

5
Connect the diode to the battery (again aligning the positives and negatives). While doing so, install a 25 amp fuse on the wire between the positive terminal of the diode and the positive terminal of the battery.

6
Connect the inverter into one of the generator's sockets. The inverter is used to convert direct current into alternating current. You can now generate electricity while riding the bicycle.
