Nothing new under the sun. Back in the late 1950's my neighbor's teenage son spoked two rims onto one hub and used it on the rear of a 26" "paper-boy" bike as an experiment in additional traction. I remember it sitting on the junk pile behind their workshop for several years. Almost everybody had a workshop and a junk pile back then. He wasn't impressed with the traction or handling. And it did nothing to help keep the bike upright like training wheels - and he didn't expect it to. Another of his projects was to splice two bikes together to make a 3-wheels-in-a-row tandem that he and a buddy used to try to keep up with traffic on city streets. That one lived on the junk pile afterwards, too.
