Motorcycles have mounts (on the swing arm orunder the tail light), if it is a pedal bike, most are just zip tied to the bottom of the seat.

If you're asking about where to put your sticker on the license plate than that would be the rear plate.
If you are asking is it legal to ride it on the highway yes. you have to put head lights, break lights, blinkers, you probably will have to get stickers and tags on it because our government sucks and a license plate on it
