Mountain biking The original mountain bikes were modified heavy cruiser bicycles used for freewheeling down mountain trails. The sport became popular in the 1970s in Northern California, USA with riders using older single speed balloon tire bicycles to ride down rugged hillsides.[1] Joe Breeze, a bicycle frame builder, used this idea and developed what is considered the first mountain bike.[2] The 2006 documentary film, Klunkerz: A Film About Mountain Bikes, looks at this period of off-road cycling in detail. However, it was not until the late 1970s and early 1980s that road bicycle companies started to manufacture mountain bicycles using high-tech lightweight materials, such as M4 aluminium. The first production Mountain bike available was the 1979 Lawwill Pro Cruiser.[3] One of the bikes that bridged the gap between BMX bikes and mountain bikes. The frame design was based on a frame that Don Koski fabricated from electrical conduit and a Schwinn Varsity frame. Mert Lawwill had Terry Knight of Oakland build the frames. The bikes sold for about $500 new and were made from 1979 though 1980 (approximate run of 600 bikes).The first mass production mountain bike was the Specialized Stumpjumper, first produced in 1981.[4] Throughout the 1990s and 2000s, mountain biking moved from a little-known sport to a mainstream activity complete with an international racing circuit and a world championship, in addition to various freeride competitions, such as the FMB World Tour and the infamous Red Bull Rampage. ++++++++++ Best Network wins more money with your youtube channel CPM of $ 3 to $ 30, and in my channel I've seen higher of $ 30 per 1000 views :) and pays 70% more than other networks Las mejores Network Gana Mas dinero con tu canal de youtube CPM de $ 3 a $ 30, y en mi canal lo he visto mas alto de $30 por cada 1000 vistas :) y paga 70% mas que en otras networks 1st) Zoomin TV 70%: Of the five networks Zoomin TV is the best CPM Very high 1º) Zoomin TV 70%: De las cinco networks Zoomin TV es la mejor CPM Muy altos https://goo.gl/kvPEji 2st) Scalelab 70%: I readily accept 2ª) Scalelab : Te aceptan con facilidad https://goo.gl/pV0WDN 3nd) GT Channel 70%: You accept easily 3ª) GT Channel : Te aceptan con facilidad https://goo.gl/yykieF 4rd) Freedom 60%: You accept easily 4ª) Freedom : Te aceptan con facilidad https://goo.gl/ZX2Ze3 5th) Recstudios 70%: You have to have 200 daily views on your channel for you to accept 5ª) Recstudios : Tienes que tener 200 vistas diarias en tu canal para que te acepten https://goo.gl/YmMB5h +++++++++++ Give Like and comment on video costs nothing, and yet it does not seem, is helpful;) and not forget subscribe THANK YOU!
