Best invention ever?

I believe Albert Einstein said the bicycle was the best invention ever and it was invented by Leonardo Da Vinci ... but I could be wrong.

It was and probably still is one of the most efficient ways of getting from A to B. It also increased the gene pool...... Anyway enough of that.

We are cycling the Camino de Santiago and I am falling in love with the Bicycle again.

This one taken in Pontevedra south of Santiago on the road to Porto, Portugal
