This sign is placed in areas where bicycles could be a nuisance or danger to others, such as on pedestrian-only paths or in indoor spaces. It's one of the most representative combination emojis that prohibits a specific action.

Besides its literal meaning, this emoji can be used to announce a situation, like "Our trip is 🚳..." when a bike trip with friends gets canceled. It's also used humorously, like playfully sending it to tease a friend who is obsessed with cycling.
