This past summer I was riding my 51 Schwinn straight bar Klunker. It has a frame bag on it. There was a kid probably 13-15 who called me out, said it was cool and asked if it was battery powered. I said no, it was just a frame bag. He studied the bike for a moment, I could see his gears turning. That’s cool he said. Thanks, and we went about our separate ways.
My neighbor’s son, 15, has also shown appreciation for my bikes, again the Klunkers with more relatable parts on them- forks, bars, saddles, ect. But it is the vintage frames that seem to grab the attention, force a double take. So there is interest there somewhere, maybe in the mixing of the old with the new.
