A local "scavenger" has made his own powered bike using two electric moters with little rubber rollers on the shaft that contact the tire. A garden tractor battery powers the ride. He uses the contraption to fuel his aluminum can hunts every evening and says they run him about 4 hours. The bike cost him $10 and the "engine" was $20 of used parts. Something tells me he's well equipped mentally for survival.
On the low-tech side...I rode an MS150 once with a 72 year old man. He had a single speed, balloon tire Schwinn and wore bib overalls and leather work gloves. Smile on his face the whole 150 miles. Again, well equipped to survive.
