It could be around the existing architecture of their brushless DC motors and controllers for their larger scale drones.

Guys, I dont understand. This test, steep uphill only in boost 8 times 30s in row with 115kg rider is not enough for you to proof Avinox overheating? Just want to understand your thoughts.

How capabel ist the DJI Avinox motor in our derating test and how long will the 800 wh battery last? We reviewed the whole system.

Backs up my post that I really don't understand how this motor got through any tests that classified it as 250w nominal, it can clearly sustain 1000W for an extended period. Not complaining, I love the fact it's obviously a very fast and strong motor, but if this can get a 250W label, why don't Bosch/Shimano produce more powerful motors that they do currently?Guys, I dont understand.

Also keeps the weight down, if they can get the performance they want with 36V, why go to 48?

Article suggests it's a 48V system.
The article is wrong, the official dji specification docs states it is 36v.
For me as an user mentioned test shows that with way I use my ebike I will not overheat Avinox motor, will do more then 2000m ascent and 60+km. All with bike about 20 kg. I really dont care if there is AAA battery 1.5V or 48V another one.
If I am involved in next gen ebike motor development, then I will care...

How does it keep the weight down? Watt hours are watt hours. Whether you use 36v or 48v, to get a battery to be 800wh it's still storing the same amount of energy. You would theoretically have a similar number of cells, just one pack with more in series to achieve the higher voltage and the other pack with more in parallel to achieve higher current discharge rates at the lower voltage. Am I missing something?
No, I'm missing something - had a brain fade.
Although, say you are using Samsung 21700 cells with a 5000ma capacity 40 cells in a 10S4P configuration gives you 36v 720Wh you cant get exactly the same with a 48v pack, you'd have a 39 cell 13S3P configuration which gives you 48v 702Wh

I agree, which is why I said theoretically, because the cells probably won't work out exactly as you want them. But as you stated, that 48v pack is lower capacity overall. If you could find cells the right size it should work out pretty damn close if the total capacity was the same.No, I'm missing something - had a brain fade.

I don't get the obsession with the max power, I really don't. We are in danger of getting moved into a category along with motorized motorcycles, if the power wars continue.
Now the obsession with best integration, lowest weight, most reliability, etc. I get.
This is the kind of thing that wouldn't bother me, I don't understand this obsession with the speed limit outside of cities..
It would be enough to add a small button to put it in City mode with the limitation, and outside nothing..
In addition, the older you are, the happier you are to have better assistance, for me it's not at all about breaking records on climbs, but rather having an easier time going up to places where I normally can't access anymore, and at home it's always the extremes (French Alps)..

Yes and no, there is a little nuance here.
Having too powerfull bike, close to e-motorbike will ban you from tons of trail/location - I exaggerate of course to mark the point.
Sure you can try to still go there but if you are caught you will pay the price.
As a gently reminder, I tend to ride where I can and got caught on analog bike on a part of a mountain where only walker can apparently go: 400 euro fees (France too!).
Last point, too powerful bike destroy the trail and natural trail really fast, it is a nightmare. We have surron and talario on our trail here and they rip everything so most of us do not shape anymore.
So no, huge power/torque is not good. Range is better, you will take more time to go uphill but will respect people / trail / nature.
NB: Still like a lot e-motorbike but not on our mtb trail.
I wasn't talking about going to extremes like the Suron either..
I still have a real enduro motorbike if I want to ride up high mountains..

Yeah I just want to materialize the fact that there will be a limit in power/torque where we will damage trail and become like a motorbike.
Honestly I think the current power is far than enough for us. I can see a turbo/emergency mode for 10-30s (Idk), but past that spending more minutes uphill should not be a catastrophic event.

I don't know how old you are to talk like that.. 
At my place it's either uphill or downhill... and with my 66 years there are a lot of impossible climbs...

I think the discussion a bout peak power was more a bout whether the availability/use of that had an impact on motor lifespan and/or reliability. That is something not yet proven with the DJI motor.
Like a few others on here I have no interest in more power than my current Bosch CX delivers. If I am riding uphill it is either to return back up to the head of a downhill trail....in which case speed is not a concern.....or tackling a techy steep climb, in which case grip and control are my priorities.

Yeah some climb might be impossible for some depending on some factor.
Like @Mikerb I climb only for DH, I don't do cruise, flat or else. This is why I am saying I do not care so much about how long the climb will be versus I want to do as much laps as possible!
For people that just want to roam, follow a long trail, I would argue that the power they can get from bosch cx is enough.
Sure being older is harder but up to a point, training outside the bike is also important as zone 2 is bearly possible for me on a mtb I am always 3-4 which does not build great cardio.

You still haven't said how old you are?
I mean, I get that you want insane power because of your age but surely you must recognize that 99% of these Amflows are going to physically capable riders, often in places that don't even have those sort of climbs. Certainly not 100% of the time.
Given the population of this forum, I'm not really sure that it is populated by very young people !!
As for the 99%, they are your own estimation..

For me. It's not about the extra power the Amflow gives you. It's the extra momentum when climbing.
Watch Rob in that comparison video. He is moving up that hill so much faster on the Amflow. So you can carry over any obstacles so much easier.
The more speed you can carry uphill. The greater your momentum you have when you have to pause to prevent rock strike. It's all these little extra helpers that can determine whether you clear a difficult technical section, or stop half way. And that for me is the challenge when technical climbing.
If you're not into technical climbing. Then this bike probably won't be that exciting. But I love technical climbing, so am very interested.

I bought a Giant Trance E+ Elite, about a year ago as I wanted an EMTB that was light enough to feel like a MTB, but had full power when I needed/wanted it. The Amflow is like the Trance on steroids, I wouldn't drive it in boost mode all the time, but the option of all that power when you need it is very appealing. If I was buying a new EMTB I would absolutely buy this, and possibly will . You can always run it in a lower mode, but dont see any reason why anyone would buy a bike with less power as a deliberate choice
You could save £1000 and buy a 'lightweight' bike which is pretty much the same weight, half the power and half the battery capacity, why would you?

I also love my Rise, it does everything I want . . but I'd definitely be tempted by the Amflow. Less weight, bigger battery, more power, more suspension - all good! What I really like is the integrated GPS and touch screen controller; fully configurable, anti-theft, route logging etc. sounds brill!

These are all fairly low end components, compared with the Amflow.

Absolutely true ....... But come on ....... it's nice when your bike exaggerates your ability .......Well yes, but I'd argue 99% enough bike for 99% of riders
