I made a copy of my bike receipt and am going to try to have it added to our homeowner's insurance umbrella- the same added policy that covers my musical instruments if they are stolen. Not going out today in the heat, but will post back later this week with what they say about insuring a bike. It will be interesting to see whether they cover theft as well as damage. For example, my policy will cover theft of my instruments from my house or traveling, or from another location where I am, but will NOT cover theft if I left them in my car (which I would never do anyway!)
