I read with interest this thread yesterday. We got our Townie Electra e-bikes three years ago and were under the impression that we were able to use them anywhere a bike could be used. That was, until we rode the York Heritage Trail on May 21 this year. We live a couple of hours away so we planned to ride part of the trail one day, find a hotel to stay over, then ride another section the next day. We parked at Brillhart Station then had a great ride (loved the trail). When we got back to the parking lot, there was a park ranger waiting for us who said we were not allowed to use e-bikes on the trail. We tried to explain that they are pedal assist bikes and don’t have a throttle and the we usually go about 11mph. He said he would call his boss, just to make sure. He got back to us with a resounding “No e-bikes”. Needless to say, we packed up and left the York area. I didn’t even want to stop and get lunch. We’re both retired and love our e-bikes. I went online to the trail website and saw that all questions about e-bikes on the trail should sent to the parks department so I did send a letter to Tammy Klunk, asking that they reconsider their stance on e-bikes. I never received a response. I was so glad when I saw that this group is working to get e-bikes back on the trail. Because of the distance, we probably wouldn’t be able to attend the meeting, but let me know if there is any way we can help.
With the exception of the Heritage trail, Pennsylvania is an e-bike friendly state. With the same drive time, you can be in Cumberland, MD. and ride the Great Allegheny Passage (GAP) trail all the way into Pittsburgh, PA. The GAP is 150 miles of scenic, well maintained, e-bike friendly trail and definitely worth the drive.
From Cumberland, you can also access the western terminus of the C&O Canal trail. Although National Parks are technically off limits to e-bikes, I ride there frequently and haven't had a problem.
