How to Generate Electricity With a Bicycle

Updated February 21, 2017

Using a bicycle is a simple way to generate electricity and get exercise - once the set-up is complete. The amount of energy you produce will depend on the wattage of the inverter and generator you use, but a basic bike generator doesn't produce enough electricity to reduce a household's electric bill significantly. However, it is a great science experiment for a person of any age.

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.

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).

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

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.

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.

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.


Use a generator with a DC motor that produces 24 volts at 600rpm (See References).
