Actually, many mountain bikers are against lumping ebikes in with "analog" mountain bikes because mountain bikers have fought so hard for access in a lot of places and access and funding is often tied to non motorized use.The Butte BLM recently released their final plan for the Scratchgravel Hills recreation area. Within it, they outlined that ebikes are motorized and therefore only allowed on motorized trails. The local outrage from bike shops and mtn bikers was significant.
This is an issue that will continually rear its ugly head, particularly by the ever growing industrialized recreation contingent.
My stance on the issue is that they are a completely different user group and should be accessed and allowed or disallowed as such.
That said, they aren't motorcycles and don't have the same impacts as "dirt bikes", assuming they are unaltered from their original classes.
For one, they are dead silent. Quieter than a regular mountain bike, usually. Second, they don't have the power to spin and do the trail and landscape damage that motorcycles can. They are heavier and probably can do more damage than a regular mountain bike, but its not significantly more.
My first concern with allowing blanket access is that difficulty in access increases solitude. Some places should be hard to get to.
Second, on heavily trafficked mixed use trail systems where mountain bike use is heavy it works well for hikers, joggers and mountain bikers to share climbing trails because mountain bikes cant go very fast uphill. The sort of trails mountain bikers want to go down arent very fun to walk down, so the bikes have their own down trails. This is the model in a lot of places, and it works pretty well.
And if you want a lot of trails built fast, invite the mountain bikers.
Allowing blanket access to ebikes ups the potential for conflict and the mountain bike community has worked really hard on making it a community ethic to be considerate to other trail users.
Giving some jack ass a battery that let's him power all over the mountain is a recipe for disaster especially since there really isn't a good way to monitor users and if/when modification kits start coming out that do make ebikes function more like motorcycles all hell will break loose. As we know, there are electric motorcycles, too.
I have no problem with ebikes on roads, even most closed roads, and I do think they could/should be allowed in some places motocycles are not but it should be on a case to case basis.
They work great for transportation for doing trailwork, SAR activities and enforcement because they can go pretty far, pretty fast and their impact is pretty minimal.
