"Performance values" of the Performance Line CX/CX-R can be increased to up to 600% support and 120 Nm of torque.
It's mastering the steepest of climbs with ease what cycling is supposed to be about? I acknowledge that some people need some assistance to enable their enjoyment of riding but ebike marketing is starting to sound like Top Gear 15 years ago, "Moar powaaaar!" I'd like to say that ebikes can get in the sea, but the batteries would just add to the pollution.

A lot of people use the new FF ebikes as shuttle bikes really. They work well at a lot of the semi-official / off-piste places that are becoming a much bigger part of MTB in the UK. Personally, as an avid ebiker I don't think all the extra is needed or a good idea really. It's a marketing arms race and we face enough problems with the press using 'ebike' as a catch-all name for everything from a Surron to Deliveroo type conversation kits. Not to mention, batteries haven't grown that much bigger, so you can use your mad power ebike to do the boring up-hill bits super-fast, but you'll be heading home after an hour, or begging a cafe to let you plug your bike in with your 1kg / 12A charger in your pack.
What does this increased output do for motor reliability?
Surely it's like remapping a car: making the motor work harder without upgrading any of the hardware/parts. Bosch would've designed the motor around a maximum output but now they've decided it's safe to increase the maximum output? Just going to end in tears earlier, no?
I have a Bosch equipped EEB and I don't use the extra 15nm from the last upgrade! Not because I'm some super tech climber, quite the opposite, but I'm yet to come across a situation where I need it or where I think the rinsing of the battery and wear to components is worth it for a reduction of effort.
YMMV.

Tears for the riders but more money for Bosch when people have to replace the motors.
I'm sure the increases are all within safe operating limits of the motors though.

Sort of, but electrical motors are far simpler than car engines, there's no cooling or oiling system, just sealed bearings in a sealed environment with grease. Even with 1300w (on the Avinox) they're not spinning that fast, nothing like a power drill. Based on what I've read on EV motors, making more power is easy and reliable, it's all the car bits around it that are harder to support more power.
It's water / dirt ingress that kills ebike motors, but they seem more reliable than before, my friends with older bikes seem to be on their 2nd, 3rd, 4th even motor (all replaced free, even out of warranty regardless of brand).
Not sure I'd want to run £300 SRAM cassettes with all that torque and power, I'd want a full steel Deore for the sake of robustness and cost, they won't come with those because they're also fighting over weight.
Avinox did it to attract attention and press for a new motor, and it's become the thing they're all competing on now. Easy to drive the motor a bit harder at the expense of efficiency/motor life. Far harder to make a motor thats lighter/more reliable/rides more naturally.
According to this the Bosch was already dropping its power off quickly before this update. Admittedly that's nearly 9 minutes at full power but if you're using it to shuttle up big fire roads at full speed you'll hit that.
I'm trying to work out what this is describing?
Bosch eBike Systems is introducing the Drivetrain Tensioner for the Performance Line CX and Performance Line CX-R, bringing maximum control in technical riding situations. The software optimisation closes the freewheel between the motor and rear wheel, reducing the free travel on the pedal to a minimum and eliminating delay whilst pedalling. The result is almost instantaneous traction, even quieter freewheel, and the rider’s input converted directly into precise propulsion. This direct power transmission enables superior control and noticeably more agile riding behaviour, particularly on demanding sections, such as when starting off on a step or accelerating out of tight bends. In combination with the performance upgrade 2.0, the Drivetrain Tensioner can protect the freewheel, ensure a longer service life, and lower repair costs.
So it's maintaining enough spin to *just* engage the free hub on the rear wheel?
