Love them as well. About as easy to ride as anything imaginable. The issues start, in my experience, when you talk big hills and big riders. Sure the geared hubs provide plenty of performance - but they do have limits - and those limits are going to be pushed with big hills, big riders, and my concern regarding our OP, a big rider trying to climb a big hill! Because I haven't seen what he's going to be running into regarding hills, I would feel bad recommending a geared hub that gets hot and overheats climbing a hill he needs to climb regularly. A mid drive is pretty easy to recommend when somebody is talking hills. Noteworthy maybe, is the fact my wife, who weighs less than half of what I weigh, rides a geared hub bike, and can go anywhere I can (within reason) with one of the most powerful mid drives available...
Worth mentioning here I think, is that I'm 6'1"/300 and 71 years old. I have, and ride, both geared hub and mid drive bikes regularly. One area I ride frequently is smack dab in the middle of an area surrounded by big rolling coastal hills. The geared hubs don't do well with me on them.... -Al
