Reach out to other vintage bike enthusiasts in your area and just throw a ride together somewhere. I know it sounds simple, but it is. Once you do that, other rides, shows etc will just happen.
We formed our group in 2014 to do monthly rides, shows, parade rides etc.We are a vintage bicycle group but will not exclude anyone from riding with us if they don’t have a vintage bike. Here’s some pics of some of our past rides and events.
