The invention belongs to the technical field of an electric bicycle anti-theft lock, and particularly relates to an intelligent brake drum cover lock. A tubular drum body is connected onto a brake drum cover; a cover plate is connected onto the drum body; the cover plate is fixedly connected onto a motor shaft of an electric bicycle; a miniature gearbox driven by a miniature motor is arranged on the brake drum cover; a rotating head rotating together with an output shaft is fixedly arranged on the output shaft of the miniature gearbox; a lock bolt is also arranged on the brake drum cover; when the lock bolt extends out and clamps the tubular drum body, the locking is realized; when the lock bolt retracts and is separated from the tubular drum body, the unlocking is realized; the lock bolt is connected with the rotating head; the motor positively rotates or reversely rotates to drive the rotating head to positively rotate or reversely rotate for driving the lock bolt to extend and retract; the action of the motor is controlled by an intelligent switch; and the motor and the intelligent switch are electrically connected with a circuit board. The electric bicycle anti-theft lock has the advantages that the intelligent switch is arranged in a cavity of the brake drum cover and is sealed by an end cover; the water and sand prevention effects are achieved; the intelligent switch cannot be easily found, and cannot be easily broken or damaged; and the antitheft effect is good.
