The percentage is just marketing BS. The motor max output is 100% no matter what the literature tries to call it. The difference is the nominal rating. A motor is often rated lower than its actual output to get around European licensing and other market restrictions. So a 250w motor may actually be a 500w motor with various limitations imposed in the controller or display firmware. This means you can say things like it's capable of 320% output in certain circumstances where the firmware allows it (like during initial acceleration), but it's max output is governed to not exceed a top speed, at which point the motor is limited to it's nominal rating. You'll often see a motor described as 500w output, but with a bracketed 750W max/peak. If you unlock the settings with programming software or other hacks to bypass the cadence or wheel speed sensors, you can run that motor at 750w all the time if you want.
Every Bafang motor I have seen in a pre-built bike is significantly firmware limited. You can always unlock more power (speed) one way or another, but that can reduce the life of the motor. You have to find out exactly what the motor is in your bike, and then google or search the forums to identify the potential output of it. And to go one step further, until you ride and compare it to another bike of the same class, all numbers are highly suspect. Bafang in particular is known to highly exaggerate their torque ratings, so without a seat of the pants assessment on the road, or an actual head to head performance test, you can't compare them on paper.

We may be talking at cross purposes here. I was talking about the assistance levels that the motor offered to riders. The Bosch motor offer anywhere from 35% to 300% of what the user inputs but from the page in the link, it looks like the Bafang only goes from 32% to 100% of what the rider puts in. This makes it far less effective than any other mid drive motor on the market. Surely this can’t be true?!
Having ridden a Bosch equipped bike and the Bafang with allegedly 80Nm, the Bafang feels nowhere near as powerful or responsive as the 60Nm Bosch!

Not apples to apples. Bosch is rating assistance level - 300% is 3x the power the rider is providing on their own. Bafang is rating peak motor output - 100% of the motors available power. They can't be compared on paper as they are not talking about the same scale of measurement.

@Homet You might be just the person I was hoping to find
I'm considering the Milano Max which I understand has the same Bafang mid drive as the Ncm Paris Max
I would really just want to raise the speed restriction from 25kmh to 30-35kmh so I'm attempting to find out if NCM locked out access to the Speed limit setting either via custom password or custom firmware
from what I read in the Bafang user manual the default password is 0512

Hi Abby,
I’m sorry but we’re returning the Paris Max as my wife didn’t get along with it. It’s packed up and being picked up today. I too have seen a couple of videos about removing the speed limit and I’m sure that’s right. You could always email NCM and ask them, they’re very helpful and reply quickly although you should probably tell them you intend to use it off road or on private land.
I would have been happy to enter the code for you into the display but as I said, it’s sealed up in the box and being picked up later this morning.
