 ===== Early Mountain Bikes ===== ===== Early Mountain Bikes =====
-In 1977 Joe Breeze, Gary Fisher and Charles Kelley started to build the first modern mountain bicycles, defined by their gearing, light weight, strength, and fat tires. Designed to go fast both up and down steep dirt trails. As soon as people saw the possibilities, innovation exploded outwards from Marin around the world. The early origins, from geared clunkers in Marin ([[http://www.clunkers.net/|1974]]) to the Breezer ([[https://americanhistory.si.edu/collections/search/object/nmah_1419571|1977]]) to the Stumpjumper ([[https://www.amazon.com/exec/obidos/ASIN/1891369636/breakawaybooks|1981]]) are well documented(([[https://www.amazon.com/Birth-Dirt-Origins-Mountain-Biking/dp/1892495619|The Birth of Dirt (3rd ed.)]] by Frank J. Berto )). What isn't as well known are the nearly 100 builders during this early period creating their own species of mountain bikes. From 1980, mountain bike sales figures grew by an order of magnitude each year from 300 bikes in 1980 to an astounding 5,000,000 in 1985(([[https://www.amazon.com/Birth-Dirt-Origins-Mountain-Biking/dp/1892495619|The Birth of Dirt (3rd ed.)]] by Frank J. Berto, pages 12 & 83 )). By 1984 every major manufacturer was making a mountain bike and there were over 100 frame builders creating very different designs.+In 1977 Joe Breeze, Gary Fisher and Charles Kelly started to build the first modern mountain bicycles, defined by their gearing, light weight, strength, and fat tires.

-Most of these have been forgotten. This is an attempt to make a timeline of ALL manufacturers and models of mountain bikes from 1977 -> 1984. Some small builders with less than a dozen frames to their name have had huge influences.+Most of these have been forgotten.
