The Stealth Lock lets you protect your bike against theft with a single kick. To activate the lock and arm the theft defense system, do the following: 


1. Line up the rear wheel with the locking pin – match one of the lines on the hub with the line on the chainguard. 2. Gently kick the small button near the rear dropout. 3. You'll hear the locking sound from the speaker that confirms your bike is locked and the alarm is armed.
