Interesting! You seem to be a bit of what we call in America (what they call themselves) "preppers". Preppers prepare for the worse... or unexpected.

I've often thought of my bicycles saddle bag as a survival kit of sorts. Mostly.... I only carry basic cycling tools. Mostly standard fare stuff but also a mini pliers, and a tube of Lip Baum (Vaseline). I do throw one of those little one-size-fits-all disposable ponchos in my jersey if there is even a remote chance of rain (I take a jacket if the odds are in favor of rain). And I carry a little cash in a money-clip (that is also a knife). I could get by on an extended ride... even overnight (although not comfortably).

I do have a backpack that is stocked with the normal EDC (Every Day Carry) items like you mentioned. But I am so hooked on cycling... I rarely spare anytime for hiking.
