I smoke regularly, but have never done so on a bicycle. I am too lazy to go through the hassle of taking a cigarette out, putting it back in my pocket, find my lighter, etc.
But a recumbent looks like the perfect vehicle to ride while smoking. I've never seen one in person. How does it ride? Is the balancing similar to riding a normal upright bicycle? Can you ride a recumbent safely (being in control) at a slow 3 - 5mph pace (like a regular bicycle)? If so, it would make a wonderful leisurely morning coffee/cigarette ride!
