>>1259104Is the registration still obligatory?
In my country you can get your bike registered by the police, they put a sticker, sign with UV marker and engrave their own number on it, and if it ever gets stolen and they find it, it will be easier for them to find it's owner. Though it doesn't scare thieves away and looks ugly (since the sticker needs to be on top tube), so not everybody is doing that.
