Heavily promoted in the Los Angeles area in the early 1960s during afternoon kid cartoon shows was the Perrywheel, a aftermarket steering wheel by bicycles or tricycles. In my early youth I thought this was about as cool as it gets to have a steering wheel on a bicycle. The ultimate showoff item that no one would have. In my neighborhood I never did see one on the street and I never had one myself, and now, after many decades, maybe that was best for all. The company was in Los Angeles, so they advertised a lot on kid television.
