Why do we see them so rarely today?
Today, these dynamos have almost disappeared. They’ve been replaced by rechargeable LED lights, much more powerful and practical. Modern dynamos integrated into wheels still exist, but the old dynamos with the small roller have become rare.
Yet they remain a symbol of ingenuity: they produce light simply by pedaling, without external energy, just by movement.
At the time, there was no talk of ecology or renewable energy, but ultimately, this system was already an example of clean and autonomous energy.
