Adding a motor is a motorized advantage. That is, the person riding the bike is not doing all of the work. Being either an E-bike or E-assist. If the motor is not powerful enough for the job, modify it, or replace with another which generates more power. If the range is not enough, find a way to get more miles out of it, by either taking more fuel or ways to easily refuel the motor. You begin to focus on how to improve the motor-aspect of the bike and not the human-aspect of the bike.

Riding a bicycle is a very rewarding experience to me; knowing I was able to travel distances at some speed solely powered by myself. There are times where I fail riding and need to walk, change the route, or lighten the load (either being gear or my belly). But I never thought of adding a motor to a touring bike as a solution.

There may come a time when that may change, however, if 50-miles a day is too much, then I would gladly shorten the distance per day over a longer period time before considering a motorized-bicycle. If the hill is too steep, I will gladly consider walking for a bit or changing the route before considering adding a motor to the bicycle.
