Bicycle registration is a process where bicycle owners officially record their bike's details, such as the make, model, and serial number, with a local authority or organization. This helps in identifying stolen bikes and returning them to their rightful owners. Many cities offer registration services to promote bike safety and reduce theft. In some areas, registering a bicycle may require a small fee, and owners often receive a registration sticker or card. This information can be useful for law enforcement and can also provide benefits like discounts on bike-related services or products from local businesses.
