I know this problem all too well.... sometimes it is easier to lift the bike than to do the whole dance with unlocking the gate/cable and re-locking it.
And that age, is exactly why a bike is great: still have to do quite some muscle work, so that hopefully when we get to that age, we can still ride
Separately to that quote: having a too heavy bike has another disadvantage: transport by car. Quite a few cars have weight limits of only a silly 45kg on the ball of the hitch, which means, with a bike rack, you got 40kg if lucky, and thus only 20kg if you want to take 2 bikes, which means with a bike sub 25kg, if you remove the battery (~3kg) and the front wheel, you barely get around those limits.
Roof rack options are not much better, as then you really need to be popeye to put the bikes on the roof, and if you ride EV car, big bikes on the roof are no good for battery range.... (if you think ebike battery range anxiety is real, try driving a car that won't move an inch when the battery is flat, at least bike you can still peddle further, then again... most EVs do 400km+++)
