I have two older brothers, one “closer to 80”, and the other not far behind. Neither of them is capable of riding at all, let alone walking without difficulty. I’ve been blessed with good fortune in that regard. My body may hurt, but it’s still functional….and riding makes me hurt less.
I haven’t yet tested my Creo with the absolute worst of hills to determine what it’s capable of, but in my case I suspect the rider would shut down first.

On the other hand, my previous bike, with 85nm of torque, would climb anything. However, it sometimes felt like instead of riding it, it was taking me for a ride, and it had no motor tuning options. I find the Creo, with Mission Control and BLEvo, and it’s lower weight and more nimble handling, to be much more fun overall.
