You made up the 30 - 70% figure and suggested it covered all cases.
30-70% push is around what our club prez uses on his electric steed. He gets home with <10% left.
But in any case I was thinking about the figures given in the article: 8.something km on the eBike vs 5.something on a normal bike does not imply that the eBike rider is getting more exercise, it means he's doing more kilometres.
Oh, and tell me where I made something up.
If the rider can't keep up with the club on an ordinary bike, he won't go out with them at all. If he goes out on his e-bike limited to 15.5mph motor help, he is likely to be working quite hard when above that speed (heavier bike, for a start) and still working below a lot below 15.5mph, as the motor won't push if you don't.
It's impossible to know if an e-bike rider does more or less work than when riding an ordinary bike. Work is effort X time doing it. There are many factors that influence both (speed, bike weight, terrain) including the psychological factor of, "Shall I go out cycling at all when I don't quite feel up to doing so on an ordinary bike".
Why not try a significant ride on one yourself? At least you'll then have some direct experience-based understanding of what they offer in help, how hard you still have to push yourself, what the extra weight of an e-bike does, etcetera.
The eBikes I know of (sample of 2) have n levels of assistance: 30-70 is more or less representative, particularly of the one ridden by the chum in question. 0% on his 22-kilo steed is available but not realistically.
Another couple of my chums switched to eBikes because most of their club had, and the rides had become too fast for them to keep up. I no longer go on my own club's group rides because our prez sets up the routes - his latest was 92 km with just shy of 2000 metres of climbing, which I can't handle. Because of his bloody battery they're never longer than that, whereas I like doing long rides. When I go out just with him he dozes along on the flat at around 20 kph to conserve power, so that I have to stop & wait every ten minutes, but on hills he goes droning on past and hangs about at the top. It's irritating.
I dare say that in a year or two I'll have to succumb myself, but if I do I'll try and adapt my current bike and use minimal extra oomph. I'll still want to do 200k rides, though.
It sounds like a human problem rather than an e-bike problem. Why can't you all in the club adapt to each other and go for a ride (on whatever type of bike you choose) in a fashion allowing you all to stay together, up hill, down dale and on the flat? After all, that's the general idea of riding together. There can still be a pace at which some find it easier than others - as long as you all stay together and occasionally allow the lad dropping off the back to catch up via a slowing of the pace. Just club good manners, really.
If you want to go at your own "natural" pace at all times then rides alone are going to be appropriate, e-bike or otherwise.
It does surprise me, though, that your club has so many members with e-bikes. No one in the club I was in had one as they regarded themselves as a racing club, primarily, even though they do slower rides (than race pace) of various kinds for various sub-groups, especially we olepharts. Even the 80 year old doesn't have an e-bike.
But when I went out on my single e-bike ride with them aboard the ladywife's e-bike, as a one-off experiment, it did mean that I could keep up with the fast lads on the steeper hills so they didn't have to wait (for me at least) at the top. I didn't go storming ahead, though. What would be the point? If I were to ride an e-bike all the time in a club I'd be using it to come up to the general pace of the group. not to exceed it.
Club riding does seem to vary across different clubs, though. This club I rode in (until I moved to Wales) generally stayed together but did allow members a "natural" pace up the steep hills with a wait at the top for the slower lads & lasses. And there was always a sprint for the village signs of note. I was aware of another local club (who never raced, with just a few doing the odd sportive) in which the various rides were often scattered over half a mile, with stragglers abandoned on occasion. That was due to poor organisation and too many infantile egos, not the types of bike being ridden.
