Batman: The Ride is a steel inverted roller coaster based on the DC Comics character Batman and found at seven Six Flags theme parks in the United States. Built by consulting engineers Bolliger & Mabillard, it rises to a height of between 100 and 105 feet (30 and 32 m) and reaches top speeds of 50 miles per hour (80 km/h). The original roller coaster at Six Flags Great America was partially devised by the park's general manager Jim Wintrode. Batman: The Ride was the world's first inverted roller coaster when it opened in 1992, and has since been awarded Coaster Landmark status by the American Coaster Enthusiasts. Clones of the ride exist at amusement parks around the world.
