The modern pogo stick was invented by Max Pohlig and Ernst Gottschall, from Germany. A German patent was registered in Hanover on March 1920 for a device they called a "spring end hopping stilt". It is thought that the beginning two letters in these men's last names is where the word "pogo" comes from.
The two-handle pogo stick design was patented by George B. Hansburg in 1957. Hansburg described the origins of the Pogo name colloquially in a story of a young Burmese girl with the aforementioned name whose father had created a crude version of the device so that the daughter could travel to the local temple for prayers. An earlier design with a single upright vertical handle patented in 1955 posed something of a risk to the user's chin. Later, improvements to the pogo stick have been made, including the Vurtego, Flybar, and the BowGo, which allow operators to jump much higher than with a simple coil spring pogo stick. Backflips and other tricks are now possible on some of these newer sticks, which has contributed to the growth of the new sport of Extreme Pogo ("Xpogo").
Whatever improvements or different types are made, the basic design idea of a person riding on a spring remains the same.
Extreme Pogo, or Xpogo, is an action sport which involves riding and performing tricks on extreme pogo sticks, defined by their durability and potential for height. Today's Xpogo sticks have the potential for over 10 ft. of height (measured from the ground to the bottom of the tip). Extreme pogo is a relatively new extreme sport and is currently emerging into popular culture as evidenced by the growing number of Xpogo athletes around the globe.
