I have personally worked at state parks to help this along, as well as ridden at Lackawanna and Rattling Creek with E bikes! There was great interest. Going forward I have seen more riders on E bikes. Everyone has been respectful.
A job well done! I like PA's Delaware and Lehigh Canal Trail, that basically follows the Delaware River from Bristol PA all the way up to the Lehigh River at Easton and points north. Just a great run, water level style with easy gradients, a well maintained path and support facilities for those not inclined to grind up and float down mountain trails. You folks in PA are doing things right!
