First of all: congrats Houston!
I bought an Olympus OMD EM5 mk2 and sold it. I never got used to the menus and there were features I liked a lot (say Live Composite) that didn't work when I needed them. Maybe I was used to Nikons and wasn't able to make the leap to a smaller and more comfortable to carry system.
On the other hand, nice quality, compact size, sealed body and lenses... Now I'm only using the iPhone camera and some time on Lightroom.

not so off topic, but aside from iphone, what camera phones are you guys digging?
If you like canon menus, get the new mirrorless canon m5 with the 22mm lens. Great little but powerful package.
If you're indifferent about canon menus, then the recently released fuji x-t20 is a great small package as well.
Go hold them in the store, or better yet as some have suggested, rent them out to try. I couldn't get used to the physical or sw ergonomics of the Oly emd5 mkii either...
There is also an M6 body that uses the same lens system. It does not have a built in finder. Instead it uses a hot-shoe connected external finder.
The Canon EOS M must have had some parts of the Canon aristocracy who were not totally convinced they needed it. So the first iteration came out and sat on the shelves for a long time before any development occurred. In the last year though, they've been convinced, and the line has gotten more lenses and better bodies. They are still just good cameras. They aren't (as far as I've heard and read) amazing. If Canon ever devoted its full energy to the line, then the camera might be great but Canon is a giant amoeba of a company and it has an internal calendar for product development that sometimes seems like it forgets that it even makes cameras at all - even their pro SLR's & lenses. They took forever to rejigger their 24mm L lens. But when they did, the new one is evidently stellar. So maybe they get most things right, but I know pros who get a little tired sometimes waiting for things to happen.
But back to the OP, none of these alternative suggestions for cameras are going to make Houston's photos any better, and in terms of form factor, it sounds to me like the way he works almost demands something like the Sony RX100 camera with its combination of high quality sensor and retractable lens. Once he goes to a protruding non-retractable lens, the portability aspect shifts to an alternative form (like a strap worn bandoleer-style) and juggling lens protection (okay, maybe install a protective filter but then a hood to cut glare?) Seems like Houston figured out a good match to begin with, and if there isn't a lot of pressure otherwise, might be the wisest choice to stick with it.
Two contrasting quotes on cameras from famous photographers (courtesy of Tokyo Camera Style.)
If you want to change your photographs, you need to change cameras. Changing cameras means that your photographs will change. A really good camera has something I suppose you might describe as its own distinctive aura.

I don’t think about what camera I should use that much. I just pick up the one that looks nicest on the day.

in that case I would go for the expensive full frame Sony Alpha (mentioned here already) + a 24mm fixed lens. or the new Fuji XT2 with the Fuji 16mm, also top quality.
if you want a heavy BRICK, get a Leica M body.
also bike on curved roads in landscape gives not much a story...;)
my name is Houston
not many come home with portraits of people they met on the road, places they saw beside the road...
i apologise, thats my personal opinion.
