From the other thread as it's more relevant here :
82w average seems like a very low average watt figure - in any mode.
In turbo it's quite hard to apply the power smoothly, so it's much harder on the drive train, especially when changing gears.
EMTB mode adapts more to your input in how much power it gives out, so you have to work a little harder than in Turbo, but the power is more controllable and the range you'll achieve will be considerably higher and it's far easier to ease off the pedals/power to change gear and then re-apply the power more smoothly.
It might be that you generally stay in one gear so in that case it won't wear your drivetrain too quickly. But, to average 82w you must be hardly applying any assistance yourself ? I think if you look at most rides on a normal bike with no motor, the watt figures would be higher than that.
From my experience, most people who ride in turbo do it to go faster and so they're also applying as much power themselves as possible - so the average power figure would normally be quite high.
I don't ride in just Turbo much anymore, but here's a Turbo only ride for example :

In this case, it's difficult to say exactly if an Amflow would give you similar range/altitude because it depends how much power the bike will try to output in turbo from very little rider input. It might react much more forcefully, in which case you'd be going faster, using more average power and would end up with less average range. I believe you can/or will be able to adjust the power settings in the different modes on the Amflow, so in theory, you'd be able to adjust it so it did match your Bosch range. However, if you wanted to take advantage of more speed/power, then you'd need to make sure the battery was proportionately larger on the Amflow compared to the Bosch to get the same range.
Hope that helps
