David has a collection of vintage bicycles that he has been assembling for over ten years. His favorite bike is a 1970s model that he restored himself. Each bicycle in his collection has its own unique history. David often shares the stories of these bikes with his friends during weekend gatherings. He believes that every bicycle represents not just a mode of transport but also personal memories and cultural significance. Recently, he attended a vintage bicycle fair, where he learned more about the history of cycling and met other enthusiasts who share his passion.
