I too am of the opinion "whatever it takes to allow someone to enjoy cycling". That said, I'm seeing way to many e-assist bikes ridden by what appear to be inexperienced cyclists at much too fast a speed.
My dad is 91 and still riding his 50 year old CCM bike. I bought him a new bike two years ago with step thru frame, larger tires for a softer ride and a suspension seat post. He tried it and said he liked his old bike better. Go figure. I've suggested an e-assist to which he replied "the day I can't ride my bike is the day I stop riding". So much for trying.
