it is possible to use piezoelectric semiconductors to generate electrical energy from the mechanical motion of a bicycle. Piezoelectric semiconductors generate electricity when subjected to mechanical stress or vibrations. When a piezoelectric material is placed in the bicycle's downtube, it will generate electrical energy as the frame vibrates during normal use.
However, the amount of power generated by piezoelectric semiconductors is typically low, so it may not be sufficient to power all the devices you mentioned, especially if they require a lot of energy like a GPS computer. Additionally, the piezoelectric semiconductors will only generate power while the bike is in motion, so the power output may not be consistent or reliable.
To overcome these limitations, it may be necessary to use a battery pack to store the generated energy and power the devices when the bike is not in motion or when the piezoelectric semiconductors are not generating enough power. The battery pack can be placed inside the downtube or elsewhere on the bicycle.
Overall, while it is possible to use piezoelectric semiconductors to generate electrical energy from a bicycle's mechanical motion, it may not be the most practical solution for powering all of the bicycle's devices. Other power sources, such as a dynamo hub or solar panels, may be more suitable for certain devices.
