Only two full-sized Tumble Bugs remain operating today in the United States—one in Pittsburgh, Pennsylvania at Kennywood and one in Conneaut Lake, also in Pennsylvania. All full-size instances are made by Traver Engineering. The ride also exists in a kiddie form. The length of the full-size Tumble Bug is 100 feet in diameter. The full-size has 6 cars, while the kiddie version had 4 to 3 cars. There are more kiddie versions operating today than there are full-sized.
