Electric unicycle

[3] Various motorized monowheels were developed and demonstrated during the 1930s without commercial success[4] and Charles F Taylor was granted a patent for a "vehicle having a single supporting and driving wheel" in 1964 after some 25 years of experimentation.

[7] In September 2004 Trevor Blackwell demonstrated a functional self-balancing unicycle, using a control-mechanism similar to that used by the Segway PT and published the designs as the Eunicycle.

[citation needed] This approach was further refined by a group of engineering students at the University of Adelaide who developed The Micycle, which incorporated a hub-motor, a Lithium-Ion Battery and a novel steering mechanism where the wheel pivoted independent of the main chassis.

[10] In March 2010 Shane Chen of Inventist filed a patent application for a seatless electric unicycle (associated with the "Solowheel" product launched in February 2011), which uses flat pedals to stand on and leg contact surfaces to allow for stable, precise control in lieu of a seat.

By the turn of the decade, several Chinese manufacturers dominate the market and continue to release EUC models with higher top speeds (above 75 km/h or 46 mph),[16] and longer range batteries.
