population density, speeds (in suburbs near the big metro areas, you are still going to be at a much higher speed) which mean not so safe riding speeds, weather (main reason why car is needed for delivery), lack of low cost 2-wheelers are the supporting infra (for maintenance or sales). I think e-bikes + delivery can make a dent, but only in the super dense cities where ebikes/escooters are popular/available.
