Montezooma's Revenge is a steel shuttle roller coaster at Knott's Berry Farm in Buena Park, California. It opened on May 21, 1978.[1] Designed by Anton Schwarzkopf,[1] it is one of eight flywheel-launched units manufactured for theme parks around the world.[2] It was the first flywheel-launched roller coaster in the world and is the last ride of its kind still operating in the United States, and remains one of the most popular attractions at Knott's Berry Farm.[citation needed] In a "behind-the-scenes" YouTube video, it was revealed that the ride had operated 1,422,272 cycles as of February 2012.[3]

Unlike many other looping coasters, Montezooma's Revenge uses lap bars to hold riders in the seats instead of conventional over-the-shoulder restraints found on most other steel looping roller coasters.[1] Following Cedar Fair LP's 1997 takeover of Knott's Berry Farm,[4] fabric seat belts were added as a secondary restraint system.[5] Jaguar! was opened in 1995.[6] In 2002,[citation needed] Montezooma's Revenge was repainted with teal and yellow color scheme.[1] In 2008, Knott's opened Pony Express, a small "out and back" steel roller coaster[7] with a flywheel launch system much like Montezooma's Revenge.[citation needed]

Launch mechanism and safety features[edit]

The ride uses a flywheel mechanism to accelerate the train to 55 miles per hour (89 km/h) in 4.5 seconds. The train goes through a loop, then ascends a tower and reverses direction. It passes through the station in reverse and ascends another tower behind the station.

The 7.6 tonnes (7.5 long tons; 8.4 short tons) flywheel, located outside the station and adjacent to the loop, is attached to a clutch and cable system, which in turn connects to a small four-wheeled catch car known as a "bob". On the front of the bob is a launch pin that seats in a socket in the back of the train. Once the bob is seated, the operators receive the ready light.[citation needed]

Two operators are required to launch the train. After verifying that all passengers have secured their restraints and checking the exit stairs, one operator ascends a podium at the right front of the train. The other operator stands on a platform at the left rear. After verifying that the launch area is clear of personnel, the front operator gives a thumbs-up signal and says, "Clear dispatch." Both operators must then press a button on their respective consoles simultaneously to launch.[citation needed]

At launch, the clutch system engages the cable to the spinning flywheel, pulling the bob and train rapidly forwards. During the launch sequence, enough kinetic energy is removed from the flywheel to reduce its speed from approximately 1044 rpm to 872 rpm.[2] The train negotiates a 76-foot (23 m) diameter vertical loop before ascending the 148-foot (45 m) front tower, then descends backwards, going through the loop a second time, running at full speed backwards through the station, and ascending the 112-foot (34 m) rear tower. It is at this point where the best "airtime" on the ride is experienced.[citation needed] The train then returns to its starting position after being slowed by 66 sets of brakes, 33 in the station and 33 to the rear of the station.[1]

During night time operation, the station lights dim at the instant of launch.[citation needed]


Justine Dedele Bolia, a 20-year-old female tourist from the Republic of Congo, died on September 1, 2001, one day after riding Montezooma's Revenge. Bolia suffered a ruptured middle cerebral artery, and an autopsy revealed a pre-existing condition. The ride was closed for several days while an investigation was conducted. Though state investigators concluded that the ride did not contribute to her death, a wrongful death lawsuit was later filed by her family in 2002.[8] The lawsuit was dismissed in 2006.[9]
