"Game changer" for me as well. When I decided to buy the RV, I knew that I needed a way to "cover ground" in many areas without extensive walking (the spirit is willing, but the flesh is weak). I thought about various solutions--motorbike, regular bicycles, even maybe a Segway? Not being a regular bike rider, I vaguely knew that e-bikes existed but they didn't surface initially. When they finally did, and I took a look, I knew I'd found the most logical solution to my quandary.
As I always do, when faced with a new arena and no expertise, I spent a lot of time online learning about e-bikes and the best options for me. Experience is by far the best teacher, but the internet is not too far behind!
I did opt for a step through model, and one with 20-inch wheels, because any "macho pride" I may have left these days has been well tempered with experience and pragmatism. As mentioned earlier in this thread, I decided a folding model would fit my needs best--as a single traveler most of the time, I can just pitch it in the back of the Jeep and have it in and out almost instantly without dealing with the bike rack questions. There are several good models--I went with the Blix Vika+ based on solid quality at an entry price ($1700). Partially due to careful research (and maybe partially due to beginner's luck), the bike turned out to be perfect for my needs. After a year and half of experience, I really can't think of a thing I'd want to change.
