Your bicycle is covered for theft if you leave it locked through the frame to an immovable object while away from home. This gives you protection if you are leaving a bike outside the shops, gym, or locked to your roof rack while travelling. There is a hard limit to how long you can leave your bike locked up, however.  Bicycles can be left securely unattended for a maximum of 18 hours at a time. If a bicycle is left for more than 18 hours, it is no longer covered for theft.
