These are bikes w/ an engine.

They don't belong on trails that are designated for non-motorized traffic.

Take them to an ATV trail and don't bother ppl w/ your obnoxiousness.

Personally I'm an engineer and custom builder of many things and have built MANY motorized bikes and such and I love them...tho not too big a fan of electric transport...just not loud enough or fast/powerful enough in general...and batteries  are a pain in the ass.

I know where my projects belong tho...and it's not on hiking trails.

...so if your ebikes are soooo badass take them where they belong.
