Mt. Hood's First Mountain Bike

On August 17, 1947, Mazamas Ty Kearney and Marianne Sinclair recruited nine friends to go for a climb. Their plan? To carry a bicycle to the summit of Mt. Hood and take it for a ride!

They bought a used 1938 World Traveler bicycle and transported it to Government Camp.

They then dissembled the bike and carried the pieces up the South Side route of Mt. Hood.

On the summit, they reassembled the bike and rode it around.

The Oregonian ran an article commemorating the event a few days later.

Their stunt garnered national attention, even reaching the desk of cartoonist Robert Ripley. Ripley commemorated the event in his syndicated column Ripley's Believe it or NOT!

Years later the Kearney's donated the 1928 World Traveler bicycle to the Mazama Library.
