The "Jesus Lock" is a type of security feature found on some bicycles, designed to prevent theft. It typically consists of a sturdy lock mechanism that secures the bike frame and wheels to a fixed object, making it difficult for thieves to steal the bike. The name "Jesus Lock" humorously suggests that the bike owner may need divine intervention to retrieve their bike if it is stolen. This lock is often used in urban areas where bike theft is common. While it provides a level of security, it is important for cyclists to also use additional locks and secure their bikes in well-lit, busy locations to enhance protection against theft.
