Amflow PX vs Pivot AMP'd for mostly flat trails?

I have a Spectral:ON CF9 2024 with EP801 and a YT Jeffsy CF Core 3 2025.

I love my Spectral but would like something a bit lighter. I am looking at the Amflow PX Carbon, PX Carbon Pro and Pivot AMP'd X0 Pro. I don't have big mountains nearby, so I mostly ride on hills and flat forests. Only occasionally do I go to the mountains and ride bike parks, but then I typically use my non-powered bike.
I've seen comments that the PX is good but not perfect in geo and not sure what that means as I think it looks very adjustable. I like the specs of the Pivot but I'm afraid it is going to be too slack and boring for me. And advice?

Right, plenty to work with. Let me write a focused reply for _hsb_. @_hsb_ - based on what you've described (rolling hills, flat forests, occasional bike park trips on the analogue bike), I'd push you firmly towards the Amflow PX and away from the Pivot.

Here's why. The Pivot AMP'd is a brilliant bike but it's been pitched as Pivot's most aggressive e-MTB -

it's slacker than the Shuttle AM with a 63.3° head angle, a Fox 38, and beefier Continental Enduro tyres. Vital found the bike relies on the motor to handle climbs, as the geometry leaves some control to be desired, and one Freehub tester literally called it

"Surron with pedals". On flat forest trails that's overkill - your instinct that it'd feel boring is correct. It wants steep, fast terrain to come alive.

The Amflow PX, by contrast, is the more versatile platform. Full-carbon frame, 160mm fork, 150mm rear via four-bar, intended as a mid-travel full-power eMTB in a relatively lightweight package. The "good but not perfect geo" comments you've seen are mostly about the adjustability being more workshop-faff than on-the-fly: five head angle settings between 65.2° and 63.2° via interchangeable headset cups, but it's more of a workshop job than something you'd realistically do on the fly. Default is 64.2° HA, 78° SA, mullet stock with 29" option

- that's a properly modern trail/all-mountain number that'll suit your terrain. Weight-wise the PX is genuinely lighter than the Pivot.
