Introduced by Louis Marx and Company in 1969 and manufactured in Girard, Pennsylvania, the Big Wheel was a popular toy in the 1970s in the United States, partly because of its low cost and partly because consumer groups said it was a safer alternative to the traditional tricycle or bicycle[citation needed].
Its low center of gravity made it a stable tricycle for children to ride, minimizing both tip-overs and the severity of any related falls.
The original Marx Big Wheel tricycle had rotomolded red, blue, yellow, and black plastic parts.
[1][2] The seat sits very low to the ground and is adjusted front and back by aligning a pair of large pegs in its base with a desired set of holes molded into the frame.
Although "Big Wheel" was a registered trademark, it was frequently used as a generic name for any toy whose design resembled that of Marx.
