Well, this post may be missing some details vs the long version I just lost when Jelly pawed the back button on the keyboard trying to let me know she's very neglected.
Let's try again now that she's happier:

It will be on flat terrain, which can be bumpy,
What does "bumpy" mean in this case, exactly? If it's a paved road with multi-inch deep potholes and/or asphalt waves inches high from the cars/trucks braking and accelerating, it's going to need a much better suspension than a few small rocks or sticks laying in the road or on a paved or even gravel bike path.
I'd like the battery inside the frame, it will be a triangle battery. I don't mind mounting the controller outside of the frame.
I haven't seen many good-suspension bikes that have a useful triangle space--most of them use the triangle, or a significant part of it, for some of the suspension components (or they just use a narrow-shaped frame, or curved, etc).
Range required, 10-15 miles at most.
At what speed, and riding style/conditions? It takes more power to go faster, or to acclerate quickly, climb hills, repeatedly stop/start in traffic, etc. A battery that may get you 15 miles with typical pedal speeds and bike path conditions may only get you 5 miles at car speeds in traffic.
Speed - 30mph average. With the ability to reach high 40's.
With a heavy hubmotor wheel instead of a light bicycle wheel, many (most? all?) bicycle suspensions won't react nearly as fast, so faster speeds are going to be a harsher ride. Tunable suspensions will help, it might require replacing the shock(s) that come with the bike to make it good. MadRhino would be the one to help with that.
Any frame suggestions with wide rear dropouts? If you can link me to any threads etc where someone has mounted a MXUS 3kw into a full suspension frame that would also be appreciated.
If you only want bicycle-looking bicycles, its' a tougher look. Even tougher since the wider stuff is probably not using the typical 10mm axle that hubmotors need dropouts for to mount in, so you end up having to make torque plates to bolt to the existing dropouts to actually hold the axle. (the actual dropouts are likely for thru-axles and the like, which wont' work with the average hubmotor).

My hub bike is a specialized big hit with a mxus 3kw motor and 2" of wheelbase extension in the custom dropouts.
so there's one frame it will fit in...but I dont' know what year he used, or what his custom dropouts look like so you can make some.
Edit: would a Giant Trance / Giant Anthem fit a mxus 3k?
There's some stuff about the anthem in these posts

If I was to use the Mac 4kg motor or a 2-3 kg motor I would look for a Anthem,
However
If I had the DD MXUS 3000 I would get a Giant Trance / Glory / Reign , instead of the Anthem.
Do you have the MXUS laced into a 26 inch rim ?
Other options are the Specialized Enduro , Big Hit , Demo 8 , FSR .
This thread talks about a pretty old anthem

Difficult to find axle spacing online...
If it helps, the official term is OLD (Over Locknut Dimension); sometimes called dropout spacing.
Oh, and here's the big MXUS 3kw thread if it helps any
