Repack Rider
Senior Retro Guru
People rode bicycles on dirt roads since the inception of the bicycle. There were groups like the Rough-Stuff Fellowship (Gary Fisher and I were members) who rode on bridle paths and trails. Cyclocrossers rode all kinds of rough terrain. Post-war kids in France and England had versions of off-road bicycles, some even jumped them.Reading the history it sounds more like it evolved in a few places. You chaps in the US were just better at marketing!
The difference maker was downhill racing. I didn't "invent the mountain bike." I invented downhill racing. The mountain bike invented itself in response.
All of the off-road groups that preceded mountain bikers stayed within the limits of their machinery. Downhill racing exceeded those limits by so much that new bikes had to be designed and built to handle that stress. In response to the new bikes, the courses evolved too. Now no one would attempt to ride a World Cup downhill course on anything but a full suspension bike with disc brakes.
It came as a surprise to me that anyone else would pay big money for a bike with fat tires.
In the last 40 years, hundreds of people have told me that they themselves "invented the mountain bike," long before I took up cycling, which is the primary reason I don't make that claim. AFAIK, no one has claimed that they invented the downhill off-road time trial before I did.
