I have a lot of mixed emotions & thoughts about how we get /use our public lands. I am 75 and when I was young I hiked & backpacked all over the High Sierras in California. I spent 2 months backpacking the John Muir trail when I was in school with a couple of friends. Back then the only way into the backcountry was hike or ride horses. It is so different today with so many different types of assisted travel (bikes, motorcycles, atvs, etc) that it is hard to keep up with everything new that is used.
I can't do what I could when I was a kid, but still hike the trail system around my home. I still can't get used to having to deal with bicycles and motorcycles on the trails. Just doesn't seem right to me. But things change and everyone pushes the envelope using all this equipment. I use an atv, but stay on approved 2 tracks & routes. Our NF rules allow game retrieval off these routes which is a blessing for sure, at least for me.
I know I got off the post's subject, but to me if it has an electric motor to assist pedaling, it is motorized.....period. If it has a battery that is used for anything other than lights, it is motorized. Pretty simple, no splitting hairs for me.
