In 1950, Modern Mechanix took a look at what was new on the road, from de-icing fluid for windshields to this amazing "Bed Bike."
The Bed Bike never seemed to catch on (or did it?), but in their write-up they note it "will appeal especially to lazy cyclists—those who like to lie down on the job." It featured "two comfortable sponge rubber 'seats' and pedals in the rear." We have a lot of logistical and safety questions about this thing, but sadly there is little information online.
Another invention they featured in the issue was a lightweight motorcycle that the owner could simply carry around. "Minibyke can solve your motorcycle parking problems. Just pick it up, tuck it under your arm." The bike was touted for being able to fit into small spaces—smaller than the small spaces the typical motorcycle could fit in—and "only" weighing 90 pounds.
While carrying around a 90-pound motorcycle and cycling while lying down may seem idiotic at best, nothing beats The Conference Bike, which was invented by more modern brains.
