October 12, 2025, Marin Museum of Bicycling

An absolute must-see for cycling enthusiasts! This museum in Fairfax tells the story of nearly 200 years of cycling history, from 19th-century velocipedes to modern racing bikes. It's also home to the Mountain Bike Hall of Fame, featuring unique specimens and stories about the pioneers of mountain biking. The collection is impressive and authentic—no replicas, but real bicycles that showcase the evolution of technology and design. An inspiring place where you can truly feel the passion for cycling.
