That fact has been lost on many. A pet gripe of mine....

Roshan sent me the metal gears on his dime and I never used them.

Did pushkar ever come through with the nylon ones he was proposing?
I also would gladly run one in my M620 that isn't over watted and would like it to be quieter. Problem is that if it is made then over watters will run them and melt them but that is their problem. At 1500w an Ultra equipped bike can feel like a small motorcycle and the need to go beyond that truly does exceed the spirit of a bicycle.
I use my speed unrestricted Yamaha PW-X (80Nm 250 W) powered eMTB for commute and I really struggle to keep up with traffic even in 25 mph zone even on the flat ground even in no wing condition. It requires to push really hard to keep the bicycle at that speed and the best speed I can reach on it going uphill or against the wind is 20 mph. This is quite dangerous and annoying for drivers even in 25 mph zone (I occupy the whole lane because of eMTB has wide bar). And there are unavoidable 35 mph zones (including 35 mph uphill) on my commute route without dedicated bicycle lanes where commuting becomes really dangerous, even there are signs post to watch drivers for bicycles.
And this is the motor limitation, not the transmission limitation (my bicycle has high speed ratio Kindernay XIV gearhub allows to keep the motor at low RPM high torque zone even at 30 mph. I can set the gear at which my Yamaha PW-X still shows close to maximum torque level on display at 30 mph but struggles to go any faster even downhill).
Would I be able to make 35 mph uphill against the wind with ease on Bafang m620 powered bicycle?

I don't know about 35, but thinking it should crack 30 easy enough.
You need to keep 2 things in mind though. 1st, you're going to be eating your battery charge big time when using a lot of power. Your range will go right into the toilet.
2nd, is about heat. As good as it is, it is NOT going to run indefinitely without over heating. The motor is totally buried inside the gear case, with no air circulation.

No, probably not even on flat ground against a headwind or it would be alot of work. If I can average 20mph on the uphill paved roads by me I think I'm at my limit both motor and physically. I usually just ride up hills at about 15mph which is 3 times faster than I can do the same hills on my push bike. But I'm in no hurry to get there either anymore.

There is huge difference between the Ultra and any 250W bike.

This comment is an aweful lot like the guy bragging up his Ford in a Chevy topic.
That's how fast my Yamaha can go if I push it really hard. But I can not believe 80Nm 250W can go as fast as 160Nm 1000W. That's probably mostly because of gearing ratios. You probably use derailleur and Bafang m620 motor even at highest derailleur gear spins like crazy at 30 mph and losses enough torque to not overcome that speed while I use Kindernay XIV gear hub with significantly higher top speed gear ratio which allows my Yamaha motor still provides enough torque to compete with Bafang m620.
Now I'm wondering how fast Bafang m620 could go with Kindernay XIV at higher gear ratio.

I have a word - PASS! As in I'll pass on that bike!

If you never watched the video in the OP, go back and watch it, pay attention to time stamp at 4:15 which ranks all the times for all the different motors, I think the video answers your question.

i posted a video demo on page one and i have to agree, this is a very odd bike.
i admit i do like the wheels! wonder how heavy they are...
Yes, 160Nm 1500W outperforms 80Nm 250W on climbing because of the motor is at lower gear and does nor spin too fast and provides more power at the same gear ratio. What I'm saying is 160Nm 1500W at lower gear ratio can not reach higher speed than 80Nm 250W at higher gear ratio (which is low gear ratio derailleur vs high gear ratio gear hub). In order to reach higher speed with 160Nm 1500W motor you need higher gear ratio. So I'm wondering if somebody uses Bafang m620 with big front chainring and small rear sprocket combined with Kindernay XIV gear hub and how fast this setup can go.

I am pretty sure some members here on EBR have that Ebike because Watt Wagons sold them

62 lbs.
There's a new model with a smaller hub motor, the basic Ebike is 48 lbs. with full suspension and at only 2K, it the most affordable carbon fiber Ebike
It's called the
NIREEKA HOMIE V23
They have created a new market segment, the low end carbon fiber Ebike, it's pretty unique in "Pearlized Red" and it's strange styling it's bound to turn heads on the road.
Actually EBR has already reviewed and tested this Ebike in their forum here.
