There has been considerable controversy around trail access for mountain bikes, both in terms of environmental impact and the safety of other trail users. As a result, bicycles are generally restricted from narrow, single-track trails, though bicycles are allowed on most fire roads. However, mountain bikers in the United States generally have access to multi-use trails.
