Join us for the Boulder Old Bike Swap—an open-air gathering for bicycle enthusiasts, collectors, and casual riders alike. Buy, sell, and trade all types of bicycles and bike parts, from vintage gems to everyday commuters. There’s no space limit in our large parking area and lawn, so bring as much as you like!
Buyers attend free. Vendors pay $20 to set up, or just $5 to bring one or two bikes.
