1. The One-Lock Method
Remove the front wheel of your bike or make sure your lock encircles the rim, not the spokes, of the wheel, as well as the bike frame. Lock your bike to a fixed object that cannot be easily broken, cut or removed. Some thieves go so far as to remove bolts from sign posts. Once you've locked your bike around a seemingly secure pole, the thief simply lifts the post out of the ground and slips off the lock. Remove unsecured bike parts, such as the seat.
