Think about it. No fuel costs (you have to fuel yourself in any case), sturdy, dependable, minimal maintenance, lasts a long time, goes anywhere, and its healthy for you. Not only that, but when you get all those maniac drivers off the roads, it can even be a pleasure. Sure, I fantasize about being able to brew my own biofuels, or having enough solar panels to charge a small electric runabout, but the reality is a sturdy two wheeler sitting in my garden shed. If the electrical grid goes down for the long count, and the available fuel supplies are all used or hoarded, you can rely on your own two feet.
