I have 450 miles on my Dmo2 on my Jamis Sequel S3 and so far I really like it. It is a little louder than my Tsdz2 with OSF but not anything I am bothered by. I am already planning a second one.
It feels more powerful than my Tsdz2b with osf. I need to get a programing cable to update the firmware though, The motor doesn't reengage fast enough after you stop and then start pedaling again and there is a run on after stopping.
Could be a hard tail version of the Luna eclipse hopefully with a rear rack and fenders. And I know they know how many people swap the stem and bars for BMX bars.
The bike has a gear shift sensor that cuts power when shifting up or down, I am sure that you could disconnect it pretty easy. It is located nest to the derailer.
My LBS was supposed to get some in in February but they haven't shown up yet. I am in the same boat as you as I have looked everywhere about the system and found very little info and only one review from a fee years ago.
I don't know about getting into the settings on that display but I haven't needed to change anything anyway. To me it is just right right out of the box.
