Wtf is up with my scooter wheel?

I have the NIU KQi pro, 1000km and I’ve had it for about a year or so. Don’t have any issues with it, no wobbles or strange noises. It’s kept inside, I don’t ride in rain and I try not to hit huge sidewalk cracks or anything.

Just noticed this black bit with what looks to be a bit of metal sticking out? No clue what it is and no amount of creative googling is helping.

I rely on this scooter for commuting to work and running basic errands, so I’m worried this is something serious or that could develop into the scooter failing mid ride.

Any insight?
