I watched the segment on 60 minutes, and do believe it is a real issue. The price of a motor was astronomical! About the size of a "D" cell battery.Fit inside the frame, attached to pedal assembly. When engaged, the pedals kept going, without your feet on them. Apparently, it's been around for years, just now being exposed. Showed one guy fall, his bikes rear wheel kept turning, while bike was on it's side. Pretty obvious it was being propelled by a motor of some sort.
