I would read the fine print entirely and carefully. There are most likely exclusions and/or limitations. For instance, a lot of policies exclude "extreme sports" and while we may not consider bicycle touring "extreme", a lot of insurance companies do. Also, check to see geographical coverage as many policies originating out of the USA are valid only within the USA, i.e. bike gets stolen in Paris, Texas, it would be covered but not in Paris, France.
Report back your findings and the policy name and company if you find out it really does work. Tailwinds, John
