How about this? I strap a 700c to my feet, put some padding to protect my legs and the jewels, then grab the pedals of a unicycle wheel. I save on frames, seating, brakes, gearing, as well as any and all common sense.
That said, there must be people who want Aerobar only handlebars, even if Aerobars tend to be less safe and less suitable for normal and group riding than drops. It's for recreational, not competition purposes, and what I really want from the bike is to be able to completely eschew locking mechanisms by being able to bag it when I go indoors.
