I've seen these here and there for years. This new Schwinn looks like it gets a lot of things right. Saw one at a LBS for $1650 the other day, where they said sales have been strong.
This is the type of product that reflects the aging of the Baby Boomers. Nicer than what was out before, pricier as today's retirees have far more disposable income, and enabling for someone to continue to be active. I could see this being attractive to say couples where one is in better health than the other but both would like to go on bike rides together.
Schwinn claims that the battery can assist pedaling for up to 60 miles. My LBS said that under most conditions it can work for at least 40 miles.
The weight is high, in the mid-40s, but still much lower than most electric or gas assisted bikes have been in the past. And it isn't immediately obvious that it has a motor, so one could ride it without drawing attention. The motor is in the front hub, battery pack under the rack.
If my wife told me that this would get her out on the trails with me, at least on a semi-regular basis, I'd pop for one.
