This is on an ebike. I got a bungee cord caught up in the rear wheel, now this, whatever it is, is loose, and the speed sensor on the bike is broken. So it is presumably part of the speed sensor 🤣
You are right, this is a speed sensor for the Steps line.
Unfortunately, I’m unable to find a serial number on the manual; you’ll have to buy a whole new one 🙆♂️
Mate, go to any Bikeshop near you and ask them nicely if they have the plastic part in their metal bin.
Alternatively you can try to click it back into place, or if your a bit crafty you can just use any magnet and attach it on the rotor in the right spot. Iv heard stories of people using fridge magnets to activate the speed sensor

As another said, if you have to tool to remove the disc, you can probably put the plastic part back in place. Otherwise, fit a magnet at the right spot and the sensor will work again!

It would probably be a centre if it had the disc bolted to it . But it looks like it is part of the disc so it will probably mean when you get a new disc it will be molded to it.

I don’t know what to google for
It appears that this is the [RT-EM300](https://si.shimano.com/fr/ev/RT-EM300-4536) disc brake from Shimano.
