I was riding home yesterday from the store, and I saw this enormous, bright red cruiser with what must have been 36" wheels. Honestly, I've never seen wheels that tall except on the old high wheel bikes. The front chainring looked like it couldn't have been more than about 20 teeth, which with wheels that big would make sense. I didn't get a good look at the crank, but I imagine the guy probably had cranks arms about a foot long to be able to put enough torque to those wheels to climb up anything other than a steep downhill descent. It was kind of cool looking, but I had to wonder how difficult it would be to ride something like that on a regular basis. The guy probably just rides it for fun on nice days, so he probably doesn't care.
