Lock the frame to something fixed
Use a good D-lock or hardened chain through the frame and a fixed anchor. If the lock has room, capture the rear wheel as well. A second lock can secure the front wheel. Check whether the anchor can be lifted or undone and whether the bike can be pulled free without opening the lock.
Make the garage or shed harder to access
Keep external doors and gates shut and lock side doors and accessible windows. Position bikes out of view from the street or driveway. If you rent or live in a strata building, check before drilling into shared walls or installing an anchor.
Add an alarm or camera where it helps
If bikes are stored in an attached garage or valuable bikes are kept in an outbuilding, think about which door or approach you would want an alert or a recording from. For advice on adding an alarm or CCTV to a home in Sydney or Melbourne, Serious Security can help with the property setup. Keep using a physical lock and fixed anchor inside the storage area.
Keep the details somewhere accessible
Photograph the bike and save its serial number and purchase receipt. Record unique marks and accessories. Check your insurance policy for any lock, storage, away-from-home and value limits. If a bike is stolen, report it to police and provide the serial number and any available footage.
