Nathaniel Adams (born March 29, 1984) is an American professional freestyle motocross rider and extreme sports athlete. A resident of Temecula, California, he attained national fame when he won the Freestyle Motocross World Championship in 2002. His nicknames are "The Destroyer" and "Nate Dog".

Luc Ackermann was introduced to motocross by his older brother Hannes Ackermann. He began his first attempts at freestyle in 2005; Unlike most motocross athletes, Ackermann started freestyle straight away and didn't find his way into racing. Just a year later, he landed his first backflip on the minibike. In 2009 he took part in the German Flight Club Series and caused a stir in the German FMX scene with a 6th place in the overall ranking. In 2010 he was able to top this success and took 4th place. Stefan Raab became aware of Ackermann and invited him to his TV Total show in the same year because he had jumped a world record with the "youngest motorcycle backflip" at the Night of the Jumps in Cologne in October 2010. At age 12, Ackermann was the youngest freestyle motocross rider to achieve this.

Seth Enslow is an American motorcyclist and stunt performer most notorious for his big jumps and equally big crashes. When he was sixteen, he bought his first dirtbike and started to race as an amateur in New York and Florida. In 1993, after graduating from Wellsboro High School in Pennsylvania, he moved to California. It was there that he met up with Dana Nicholson who had just founded Fleshwound Films with fellow filmmakers Jon and Cami Freeman. In 1994, they released their first film Crusty Demons of Dirt showcasing the underground motocross movement out in the deserts and badlands in the United States. The film gave Enslow notoriety for overjumping a sand dune and crashing hard. The distance he traveled was never measured but it is speculated to be around 200 to 250 feet (61 to 76 m). The movie quickly spawned a sequel and, once again, Enslow made an impact by coming up short on a jump and landing on supercross racer Jeremy McGrath's practice bike. This notoriety made Enslow one of the first bike riders to receive sponsors without having a racing career. Enslow, who by this time was making a living riding bikes, decided to break the world record of 251 feet (77 m) set by Doug Danger. He started practicing by jumping ramp jumps over kegs of beer, cars, motorcycle and other big objects at different events. In 1999, he broke Robbie Knievel's (son of Evel Knievel) 226 feet (69 m) record for most motorcycle jumps. However, Enslow's triple clamps broke, which disconnected his front end from the frame, resulting in Enslow diving head first into the asphalt. But Enslow was soon on his feet and even signing autographs before leaving the venue.

In the 2002 X Games, Metzger won the Freestyle and Big Air events and got second place in Step Up, earning him an estimated $100,000 in three days.

Metzger lost one of his testicles when he failed to land a Nac-Nac Backflip, and he spent six days in the hospital there. On May 4, 2006, at 9:26, Metzger completed "The Impossible Jump", doing a world record backflip over the fountains in front of Caesars Palace, Las Vegas, seen live on ESPN. He is the first person to complete a backflip over the fountains, and only the second person to ever successfully land that jump. The others to attempt the jump over Caesars Palace's fountains include Evel Knievel, Gary Wells, and Robbie Knievel, of which only Robbie landed successfully. He also set the record for distance, landing 125 feet from the takeoff ramp. Metzger recently has been doing freeride. [citation needed] Commonly known as "The Godfather of Freestyle Motocross", Metzger was one of the first riders to begin doing basic tricks such as heel clickers and can cans. His acrobatic accomplishments include being the first person to complete back-to-back-flips (two flips on two consecutive jumps) at the X Games.[1] As a result of his popularity, he also appeared in Freekstyle, a 2002 motocross racing game for the PlayStation 2, Game Boy Advance, and GameCube, and his image is on the cover.[2] He invented the heel clicker (Frezno Smooth). Metzger has appeared numerous times on the Discovery Channel's extreme sport show Stunt Junkies. In the last episode he appeared in, he was seriously injured; while attempting to execute a jump with a back-flip between two barges, he overshot the landing ramp and suffered a compression fracture of the L4 vertebra in his lower back.[3] He invented the "McMetz", a trick in which the rider puts both feet over the handlebars in midair, then sweeps them backward towards his arms, takes his hands off the bars to allow the legs by, then remounts the bike after floating detached from it for a split second.
