Minibike companies include Arctic-Cat, Taco, Rupp, Heath, Gilson, and Fox, many of which also made other power toys such as go-karts, choppers, and trikes began manufacturing to meet the demand. In America, the peak of the minibike era was from the late 1960s to the early 1970s. Many of the brands, foremost Rupp, gained a fan base of enthusiasts and owners.
