The principle is different. Ribbon only depends on the friction between a piece of cloth and a fixed disk to produce resistance. You can imagine how uncomfortable it is to ride, because there are few original parts and simple structure, so the cost is low and the price is low, but there is no comfort at all.
The magnetic control vehicle relies on the attraction between the metal frisbee and the magnet to generate resistance, and uses two pulleys to transmit power. When riding, it is silent, stable and comfortable.
That's all I know. I hope I can adopt.
