Make sure people aren't getting confused between ebikes and pedelecs, there is a difference. Our bikes are allowed in the national parks,almost all trails permit them with exception of a few.I think traditional mountain bike riders are just being snobs. If you are young and work hard at staying fit, having someone who is perhaps older, or just in questionable physical shape riding the same trails as you would raise your hackles. When these younger riders age like many of us already have, they will wish they could return to their favorite trails on an eMTB. SO, predictably, a critical mass of future older riders will demand eMTB's are permitted on all trails. Sadly for many of us who have one or two decades of riding left in us, we are denied what some may consider a certainty for all riders in the future. I fail to see how eMTB's cause more damage to trails in areas where riders are trucked to the top, and blast down the hills with a full tank of energy. The beauty of eMTB's is being able to enjoy climbing hills with support, and reading the top without being exhausted. Who wouldn't prefer that to chucking your bike in the back of a pickup and squeezing into a cab for a dusty ride uphill?
I live in the Canadian Rockies and so far, Banff National Park has banned all motorized vehicles including e-Bikes. Alberta has as well at the Nordic center in Canmore. There are only a few trails that permit e-bikes. And they are not the sort of trails our eMTB's were designed for. The e-bike permitted trails are typically flat, gravel and asphalt paved paths. SO, do you take a chance and ride on the trails that our bikes are banned from? The fine in the Banff National park is steep including a mandatory appearance before a judge.
