It was always my understanding that the AZT on the North Rim was open to bikes. According to the GC Backcountry management plan update bikes are not
officially allowed on this segment. So I guess that means we are unofficially allowed. The No Action Alternative A continues this policy. All three of the Action Alternatives B, C, and D change the policy to officially allow bikes on the North Rim segment of AZT.
I don't see any other major impacts except that Boundary Road on the South Rim would be officially open to bikes in Alternative B whereas it is currently classified as an unmaintained hiking trail. I presume that means bikes are currently not allowed.
There are a number of changes to backcountry use policies that may affect hikers, camping and guides. Take a look if you are interested.
See the management plan project pages. The executive summary has pretty good info, look at Arizona Tr, Bicycle Access and Trails and Routes

The Exec Summary in the link is easy to scan, and there is a good map on Page 35 of the full EIS document. Access for comments is on the left hand side when you follow the link.
