I have a serious Kryptonite chain, and I keep a cover over it. Register the chain with Kryptonite, and keep your codes written down. Their warranty claims to replace the value of whatever was stolen, assuming they break through the chain. Some folks add numerous locks, and thing to make it harder to roll away.

That said, any lock is a deterrent, and never a guarantee. Some folks Airtag their rides too.

I've had a Hyperscorpion for about a year and a half and it mostly stays locked out front. When I'm traveling for longer periods I bring it into my fenced back yard and keep my locks on it anyway.
