Also, you generally have to dress more warmly for biking than you do running, if you're really in danger, ditch the bike and run to the nearest house. You'll stay plenty warm.

I can't think of a situation where I'd be far enough from civilization to need an "emergency" heater while biking.

I'm not knocking your thing, I think it's cool, I'm just stumped as to why you'd need it. (And wouldn't it just be easier to bring an actual furnace with propane/butane fuel if you're doing something like ice fishing?)
