Actually, it has been shown in the US that greater numbers of mountain bikers has, in the higher population density areas (like the UK), let to greater restrictions and reduced access. If you have an area that has no official mountain bike trails, if there are only a few mountain bikers then they can pretty much go where they like; if you suddenly get hundreds turning up then the areas available to them will get restricted – that seems to be how it goes.
Improved transport provision? Can you clarify that please?
Yes, I believe I made the point about the Dutch, but that’s cycling, not mountain biking. The thread is about mountain biking specifically, not cycling in general.
I still don’t see why mountain biking must be seen to be accessible?
More people mountain biking would not benefit me personally, no, so I’m quite ambivalent. I don’t care if anyone else rides a mountain bike or not. In fact, the recent swell in numbers simply seems to mean a greater number of thefts of high-end bikes as they are now more of a target, and greater numbers of people on the trails leading to less of a feeling of getting away from the world (which is mostly why I ride offroad as opposed to on the road). Why are either of those good things?
