Using eBikes to get the unexercised moving is a great idea.
After considerable experience on an electric-assisted bike, and watching the people who stop me to talk about cycling or even getting an e-bike, I don't know that I agree.
In my small town the only successful electric bike is mine. And I was already an experienced and committed cyclist (gave up the car altogether in 1992) when I electrified for health and geographic reasons (two heart surgeries, then moved up the steepest hill in town). The rest fall into two categories of failure:
The unfit, who don't hear when I tell them the pedelec they can buy ready-built only
assists their pedaling. They hear "electric motor bike". Their e-bikes have the same fate as standard pedal bikes bought by such people: after a few rides they end up in the garage, unused and unloved. Some of my pedalpals never service their bikes: they just buy a hardly-used expensive bike out of such a person's garage for a maximum of fifty euro -- many will pay you to take the
thing away -- and ride it into the ground.
The hopelessly untechnical, who don't hear when I tell them to buy the biggest battery they can afford (and this is an affluent area, Range Rover heartland, so they can all afford a humongous battery) and that they should treat the battery like a venerable object in their religion, recharging it after even the shortest ride. They complain that the dealer promised them x miles, when I know bloody well that the mickey mouse battery they bought because the dealer said it would be lighter is only good for one-third x, and then they rode it flat, repeatedly, and grudgingly recharged it, and in short order ruined it.
To operate an e-bike successfully (success being defined as adding to your fitness and longevity), you need to be informed about what it can do for you, and how it does it. It does the e-biker no harm to know what a coulomb is and how it affects what is possible on his e-bike and what he can and should demand of it if he is not to wreck the battery and burn out the motor. Secondly, discipline is required, as in any sport; it's a hard thing to be forced to learn late in life, and most falter at this high bar; it helps to have been an athlete of some kind earlier in life, again in order to have reasonable expectations. Third, there's a lot to learn: not only about electronics but about physiology (how will you measure the effects and results?); some people just can't help getting a migraine when one brings up gear ratios. Fourth, but not finally, it actually helps to have considerable experience of unassisted cycling, because that inculcates the right attitude; without it, in my experience, failure through overblown expectations is just about guaranteed. There are other contributory factors to failure, but these mainly intangibles are, I think, the main causes of e-bikes -- in fact, bikes in general -- ending up unused and unloved in garages, and their owners dying before their time.
I think the OP is fortunate in that he at least has from general cycling experience a yardstick against which to measure e-bike outcomes so definitively.
Interesting thread: it forces one to clarify vague suspicions.
