Long before the mountain bike entered our global consciousness, the cycling enthusiasts of Northern California's Marin County rode modified pre-WWII bicycles down the slopes of Mount Tamalpais. They developed their bikes through rigorous field-testing, often risking life and limb to do so. Some of these cyclists were Category-1 road racers looking for a new way to train during the off-season. Others were simply fun-loving hippies looking for a new way to commune with nature. Their early bikes were scavenged from dumpsters and junkyards. It was from these humble beginnings that a multi-billion dollar industry, a form of recreation for the masses, and an Olympic event, were born. These hefty steeds were affectionately known as Klunkerz.
Unfortunately the movie Klunkerz is not yet available on Disney Plus.
