Don’t know how true it is but dji’s have been eating drivetrains according to the inter webs…. Kinda makes sense Bosch claimed the reason they did not up the power on the “gen 5 “ when it was released was drive train durability.
It's 2025 Is an Emtb in your near future?

Bingo.
It is rumored that when the next firmware from Bosch is released, you will have to opt it to the full power setting and that it must be done through their flow app.. When doing so you must confirm your acknowledgement that your will significantly shorten lifespan of drivetrain components and shorten runtimes. Of course everyone will do it.
Yes
Switch to Shimano Linkglide 11spd
Someone needs to design a 7 or 8 speed Ebike drivetrain.
I would love a 7 speed drivetrain for my Amish bike, as long as it has a 50t. Even a 5 speed would probably be enough.
SRAM came out with EX1 8sp for ebikes years ago.

100%. With a motor assisting you don't need 12 gears. I always find myself double shifting in either direction all the time when I'm ebiking so having fewer gears with a more robust drive train for ebikes make a lot of sense... and use steel for chain rings and cassettes. Ebikes are already heavy so an extra half a pound won't make a difference.

ePinion. It's out there but I think it is still under development.

Nicolai sells one, but they don't seem to have any US distribution... and with the current... situation... I doubt that will change anytime soon. Videos and reviews I've read look good.
A great comparison between CX and SX drive units. Well worth a view.
I also finally rode a DJI motor this week. It is crazy fast for sure, but here are some important notes:
-The rep flat out said that NO shimano drivetrain will be able to handle the much torque. You will simply destroy a shimano drivetrain with this system. (this should be your first clue that these are pushing e-bikes a bit far)
-While SRAM transmission can handle this drive unit, look for VERY fast drivetrain wear and costs associated. (sram trans cassettes aren't cheap)
-This is not appropriate for beginners. I have 1000's of hrs on off road motorcycles and I dozens of ebikes. This will get people hurt.
-These bikes will negatively impact trail access and potentially get ebike banned. (they are that fast)
-Customer service in the US is literally non-existent. While you are not out on your own here, it's close.
My .02 is that while this is a impressive feat of power delivery, I am drawing a line in the sand at 100nm. These things will cause conflict, potentially injure people and cost a lot to own with very short drivetrain lifespan.
I only have about 700-800 hours on an ebike but I really don't see the point of that much power. Riding Telemark yesterday I turned the power down in the techy sections for better traction and control. Only time I end up needing more power is straight and smooth uphill or just chilling on a long fire road. I'm on a Shimano EP801 btw.
Did you notice a significant amount of flex on this (Amflow). That's been the constant knock that the rear is super flexy. The other complaint I've heard is it's a real battery drainer.

Endurance Guy: Tolerates most of us.
9-speed Microshift is what I ran on the Vado. It has the same range as XX1 but is like $200 for the entire group set. It’s bombproof.
What about the torque cant shimano handle, the chain?
