Tricycles for grownups have been around as long as the bicycle has. And while they are seen less often than bicycles, they do have their merits. They may be appropriate for those who need a more stable ride, or who want a wide platform for hauling gear, or for women or Scotsmen who ride wearing skirts.
And then there is the Rungu. The name means “club you use for knocking somebody on the head with,” which seems inapt for this thing:
That’s right, upright posture, fat tires, and two wheels in front. Not in the back, where the weight is, but in the front. They argue this is better for riding on sand, and they sell a special model with extra-fat tires if that’s your dream.
