Best bike design for getting old

[buddybikes]

Yes I am getting old, and have had 4 back surgeries as well as knee. I have just gone through loss of my beloved parrot, Buddy 28 years old. Week later and I still glance into his corner. Great bird that was friendly to everyone. Anyways, why not, let's get a nice bike made that will handle me into my 70s. Main concern with current Alchemy custom e-Ronin is feeling "high" on the bike rather than close to the road. Also drives like a truck, nimble is not what it is. I am riding 100% pavement, if I lived closer to some pack gravel probably be doing that but unless we move or get a second home (our daughter moved to Ft Collins so guess that would be possibility).

I put my deposit with who I know and trust, three horsemen at Firefly. (yes I know they have few more but these are "the" guys.

Kevin will certainly dial me in, but as I start to think suggestions for my next dream machine? It will use the newest/lightest/smallest Bosch drive. I want to feel safer on it, not pound my wrists, shoulders and neck. (thinking of suspension stem or a light front suspension).
