Oxforddictionaries.com definition:
mountain bike
(noun)
"a bicycle with a light sturdy frame, broad deep-treaded tyres, and multiple gears, originally designed for riding on mountainous terrain".
Or...
the Definition of mountain bike noun from the Oxford Advanced American Dictionary
mountain bike
(noun)
"a bicycle with a strong frame, wide tires, and many gears, designed for riding on rough ground"
So apparently single-speeds aren't real mountain bikes. :facepalm:
Neither are Clunkers as they are too heavy and the Raleigh Bomber as its frame is not lightweight or strongly constructed and its three speed does not constitute "many gears".
What about bikes using NuVinci hubs with their step-less gearboxes?
In order to tighten up these definitions a minimum tyre width and gearing ratio needs to be stated.
i.e. 1.75" (44.45mm) minimum tyre width. (the width of the tyre fitted to narrowest mainstream mountain bikes pre 1985. And minimum 3:1 highest to lowest gearing ratio.
The above does demonstrate that the invention of the mountain bike was not a giant technological leap forwards. But happened when someone put fatter tyres and lower ratio gears on a lightweight bicycle frame. The Geoff Apps bikes also included trials motorbike geometry and components combined with the biggest diameter tyres that could be sensibly fitted.
