Instead of adding a motor, maybe upgrading to a simple light robust bike might be effective, Cugel could downgrade to a cheap heavy bike to slow him going uphill to level the playing field
The ladywife's bike weighs just under 15Kg with all the bits on, including not just the motor/battery/BB gearbox but also the mudguards, bottle cages, bottle & tool bottle and the pump. It can be ridden sans motor & battery which drops out of the frame with a push of a button. This loses just over 4k so the bike becomes as light as a typical steel tourer - although it's configured as a CF framed endurance road bike.
Perhaps you haven't cycled the hills of West Wales? For an ex-racing fellow they are do-able ..... although I do, these days, need at least a 1:1 bottom gear, preferably lower on the worst ones. I have an FTP of about 230 watts and can probably hold 260 for a minute or three for the short & sharps. The ladywife probably generates an FTP of about 130 watts, not being an experienced cyclist (yet) so would be walking up a lot of those hills, even with a 7kg bike. A low enough gear would be so low to twiddle, she'd likely fall off sideways!
She weighs 8st 8llbs to my 13st 1llb (according to the scales).
In practice, she goes up the steepest long climbs in the middle power setting, pedalling as hard as she can to get the motor to give the maximum help for that setting. She drops me (trying my utmost) at a differential of 0.5 - 1mph. That means both of us get proper exercise, with plenty of aerobic threshold stuff. Such exercise is part of our intent, since not using it will only lose it. We old gimmers (well, me) have to keep at it or wither!
I feel you don't really understand electric bikes, in all their variety, nor the nature of riding a-one such as that of the ladywife. It still takes a lot of effort, as the BB gearbox strain gauges won't let the motor work hard unless they feel the pedaller also working hard. Perhaps you need the experience of riding such a bike before emitting opinions, suggestions and other ponderings?
The Focus Paralane2 and similar road bike-style e-bikes are a pleasure to ride in the usual fashion of road bike riding. One clips along quite fast, enjoying the high heart rate, technical road management and all the usual pleasures. Why, man, we even sprint for the village signs! And up the hills, naturally.
