I have a geared Dapu in the BH, I like to pedal without power on it. I can stretch the battery from 30 miles to over 50 with out power
Just read Court's reviews for the St5 Abs version and now went back here to reread some stuff.
Regards to Nitro : I was amazed at how ezee it is to peadal it w/o PAS , only did a few x during my almost 15,000 miles and everytime it was like wow this is a completely new bike and it is so easy to pedal it and by the way I had the motor cable broken and I fixed it , it was amazing because I wasn't sure if it could be done.
And while fixing the motor I learned something new about the torque sensor and this might completely fix your Nitro( i still want to buy it from u though
) so basically the tighter or less tight you have the thruaxle screwed in , the less/more responsive the torque sensor becomes ( anything below 0.8V makes the TQ sensor responding a bit slow or maybe very slow depending on each person sensitivity...)
You can find the current value for the TMM4 TQ sensor in the settings when you keep pressing the two buttons at same time (top button and bottom) and you should have the TQ @ or above 0.8 if it is above 1v , the ride or response will become quite jerky or very fast ( the way u were describing it) so that means that the thruaxle it's not tight enough.
Mine's set @0.78 right now and b/c i use a single ring upfront -48T - the response from PAS is not as slow as it should be but this way i know that the wheel is also very tight in the drop outs and won't spin out like it did for me recently, see below.
There is also a big risk involving the rear wheel : that is when the TQ vlue is @1v or higher that also implies that the thru axle it's not tight enough and that can actually create a big problem with the motor wheel spinning out and breaking the cable ;
that's exactly what happened in my case but that's also because I was changing the tire/tubes quite a few times so the dropouts got worn out(I actually had those changed too they can easily be changed -2 small parts that can be ordered , i changed those one time but it looks like they need to be changed every 6-7k miles or just need a lot of care when moving the rear wheel in/out.
I would highly recommend the thorn proof tubes from specialized.
And also a torque arm, i just installed the Grin tech one, this way the wheel would never spin out.

The problem I see with the Stromers again is the support (for myself I could probably fix them although that would take about six months of learning especially for the ST5 ) also the big battery it's problematic because if you need to do a long ride need two of them b/c of the inbalance created; and then they become too heavy , cannot carry only one because say i put in inside the left pannier than the balance is not that good and yeah this bike is too heavy(75lbs maybe 80lbs with the Wren fork)
I'm Very excited for the Vanmoof V and until that one comes out we don't have that many options.... I also like the Sonders LX ( But it would need a lot of parts upgrades ) because it is very fast 35 mile-per-hour top speed. There is also the Zen with the Shakti but since it's v. new it would need some testing 1st , I would rather let others be the beta testers and then I can evaluate it. But so far looks like a very professional project.
