Hmmm interesting.
I guess you could try to install hwinfo, and check the drive health for that nvme drive. Also check if there are any other errors reported there.
You could also try to boot your pc in a live install of Ubuntu, or windows2go, and check if the weird drive activity persists.
And if it continues, I might suggest resetting your bios. I’ve heard these kinds of issues can occur with sata drives, but it might also happen with nvme.
Do note that before you reset the bios, you should set your current settings as a bios profile, so you could revert back to it if anything goes wrong.
If nothing works, I guess check what other users recommend, and if that doesn’t work, try to get it replaced under warranty.
As always good luck!
IIRC motor power has to be limited to 250w, and the speed gouvenor is set to 24km/h.
I have one of those E bikes that only run the motor when the user pedals, and it wasn’t hard to remove the speed limit. The bike paths here in Oslo are a bit sketchy sometimes, so I usually dont go above 30km/h, though my bike can reach 40 at full battery.
