I'm 28 and into old bikes in the same way I like any other tool or machine designed, drawn, or made by hand. Most modern bikes don't appeal to me, largely because the old ones are easier to work on and cheaper to buy, and they have actual paint colors and the good uns were made with some longevity in mind, and steel will last with care. They usually have some history and connection to the people who built them too. That said, more people riding is the most important part imo. In the end, we all end up in the landfill. Yet, passing on this hobby means fewer new disposable bikes will be bought. Things already made will remain useful. Otherwise see to it that they are recycled. I'm expecting cheaper prices for the bicycles that interest me in the years to come.
