Thats because the added weight and power tears up trails, and the stewards hate that shit.
But that’s not actually enforceable?
According to federal law, I mean?
I’m guessing each state and county can make their own laws
A “no motor vehicles” sign would not prohibit e-bikes. However, I see no reason why a trail couldn’t enforce prohibition of a list of categories that includes both motor vehicles and e-bikes as separate items.
The federal law applies to the public roads. Trails are NOT public roads. They can have any restrictions their management wants. Just like private roads at supermarkets - they’re not public roads and supermarket can say no Ford cars here and you have no recourse there.
By not public, trails are private because they belong to the state, you mean?
