My son found this in our garden… and now we’re wondering what this strange thing is. Do you know what’s in the photo?

When the bicycle became a spaceship

Having a dynamo on a bicycle was a real privilege. Only one boy in the entire neighborhood had one. We eagerly awaited him as if it were an event. When he arrived, his headlight lit up the street, and we all held our breath. To us, it was like a futuristic device.

For months, I dreamed of owning one. Riding my bike at night, seeing the road ahead illuminated, feeling grown up, almost adult. The Dynamo wasn’t just an accessory: it was a ticket to adventure, a promise of independence and self-confidence.

Simple… but great technology

In retrospect, this invention was incredibly brilliant. A small generator attached to a bicycle and converted kinetic energy into light. Nothing superfluous, nothing complicated. Just a solid mechanism, often noisy, sometimes a bit sluggish in the rain, but incredibly effective.

She also learned something essential: to have light, you had to move forward. To stop meant returning to darkness. A beautiful metaphor, when you think about it.

Why did these Dynamos disappear?

Today, they have been replaced by powerful, lightweight, battery-powered, and quiet LED lights. More practical and reliable, certainly. But also significantly less emotionally charged.

Newer generations haven’t experienced this distinctive sum, nor the pride of creating their own light. Yet this object still evokes nostalgic feelings among those who used it.

What does this object really tell us?

This everyday technology found in the garden is more than just a forgotten piece of metal. It tells the story of a time when technology was tangible, understandable, and almost instructive. A time when people repaired and created things, and every object had a soul and a story.

As I held it in my hands, I realized that my son had just discovered more than just a piece of bicycle accessories: he had discovered a piece of collective memory.

And you, do you remember the exact moment when your bike first lit up, simply because you were pedaling?
