Hope I'm not duplicating. The Swamp Rabbit Trail in SC. Travelers Rest to Greenville. 22mi. Goes into the citys river district then down to the zoo. Very well maintained but crowded on weekends. I also saw the Creeper Trail (VCT) in SW Va. Last I heard, no eBikes. This is still worth it on an acoustic bike. You take a shuttle to the mountaintop and coast back to Damascus. Really scenic.
The last time I rode the Virginia Creeper Trail, I saw a few ebikes. They may not be permitted but enforcement is almost non existent. If you're doing the trail one way downhill, you really don't need an ebike anyway, just good brakes due to the steep downhill slope in spots. Any way you go, it's a good ride.
I added the Swamp Rabbit Trail as #51 on the list.
Thanks for your input!
