June 3 is "World Bicycle Day".
In addition to road bicycles, racing bicycles and the brand new e-bikes, the bicycle has always aroused interest and curiosity, stimulating inventiveness.
In 1905 Karl Lange patented a "Double bicycle for looping the loop", perfect for those days when you feel upset.
Thanks to Elena Genito and Mariavittoria Versaci.
