BIKE COMMUTING 101: LOCKING STRATEGIES [EcoVelo]
Bike commuters must often leave their bikes unattended for extended periods during the workday, providing ample opportunity for bike thieves to do their work. Storing your bike within a secure area is always best, but when a bike must be locked outside for the day, the following locking strategies will help ensure it will still be there when you return for the evening commute.
Invest in a Quality Lock – A high quality U-lock is your best defense against professional thieves; cheaper U-locks are easily defeated with a crow bar. A good one will run $75-$100. Cable locks are versatile and convenient, but most are easily defeated with a small bolt cutter. Bike-specific chains offer the reach and versatility of cables, while providing protection similar to the best U-locks, but they’re heavy and expensive.
Use it Wisely – Be sure your lock is threaded through one of the triangles in the frame, or if possible, through the rear wheel within the rear triangle (the rear wheel cannot be pulled through the rear triangle, and it’s extremely difficult to cut through a built rim). Locking the rear wheel in this way secures both the wheel and the frame.
