I personally would use my bike in many bug out situations, primarily because I have commuted and toured since 1970. I still typically ride 20 miles plus every day. A bike is a viable option for me, but what about my wife and daughter , who do not ride?

It is certainly useful to talk about different kinds of bikes, but the most important element in practical bike use is the motive power - the rider spinning the cranks. There are those challenged by a three mile ride, while others can knock out a century with no probs.

If you include a bike, any bike, in your disaster plans for heaven's sake, get it out and ride. While you are at it, learn how to fix flats and deal with other basic problems.

If I have to bug out on my bike, it should be just another fully loaded touring day, probably with a few novel distractions. While I am a bike fan, I still retain other options - cars and trucks have desirable aspects, too.
