Depending on where you are it might give you broader trail access. Most trails in these parts emtbs aren't allowed by default and up to the land owner. We have a few places where they've allowed access but does mean that trail access is a bit sparse YMMV.
Recently upgraded to a Powerfly 9 FS(which is awesome!), one thing that I wasn't expecting relative to our other Bosch e-bikes is how noisy the Performance CX motor is. Even on the first couple levels of assist it sounds like an angry RC car. Easily louder than the tire noise on either pavement...
