Triple Backflip
Backflip is kind of a street name for a gymnastic element called somersault. According to wikipedia this is an acrobatic feat in which a person tucks in mid-air and moves the feet over the head. Nice. According to many riders it is actually an easy trick that just requires some determination and balls to do it. The following people look like they have six balls :)

huh, is the first one on purpose or by mistake :D
