The NPS understands that there are potential impacts from mountain biking,
as well as other activities that are permitted in national park units. In
2012, the NPS published regulations for bicycle use in NPS units. The
attached Federal Register notice covers issues relating to bicycle use on
Thanks, but there are serious problems with that document:
1. "For existing trails, the final rule prohibits bicycle use where
significant impacts would
occur." Significant impacts always occur! That is the nature of mountain
biking, which is an inappropriate use of natural areas.
2. The fact that it may be "popular" is irrelevant. Many destructive
activities (e.g. ATV use) are popular.
3. The laws of physics and biology are identical in all areas. There is no
reason to have different rules in different parks. Having to fight each new
trail is an unfair burden on people who want to protect the parks.
4. Bicycles are prohibited in wilderness, but wildlife are not restricted to
wilderness! If they deserve protection in wilderness, they deserve
5. History shows that mountain bikers have no respect for habitat, wildlife,
or other trail users. Possession of a bicycle gives one too much power
(threat of injury and disturbance of the nature experience) over wildlife
and other trail users.
6. Mountain bikers always ride through creeks, rather than carrying their
bikes. That shows that they don't care about protecting habitat.
7. There is no such thing as a "sustainable" trail. This is pure fantasy.
Eroded soil doesn't return to life nor to its position on the trail.
8. It is well known that a helmet doesn't protect one from serious injury or
death. An activity that requires a helmet is obviously inappropriate in a
9. "Generally, impacts to soils, vegetation, and wildlife from bicycles are
similar to impacts from hiking". This indicates that the NPS hasn't
understood the research on this topic, and is relying on poor "science"
written by mountain bikers. For a review refuting those studies, see
10. "Bicycling is a family-oriented activity that contributes to the health
and well being of those that enjoy it". You have really drunk the mountain
bikers' Kool-Aid! Your Final Bicycle Rule reads like mountain biking
propaganda! See http://mjvande.info/mtb_dangerous.htm
for why mountain
biking is decidedly not "a family-oriented activity that contributes to the
health and well being of those that enjoy it".
11. The Rule sounds reasonable, but is not, because it relies on poor
science. It reads exactly like mountain biker propaganda. In fact, many
statements were lifted directly from such propaganda. Apparently, the Rule
was written by a mountain biker."
