An electric monowheel called Dynasphere was tested in 1932 in the United Kingdom. [11] [12] In 1971, an American inventor named Kerry McLean built his first monocycle (aka monowheel). In 2000, he built a larger version, the McLean Rocket Roadster powered by a Buick V-8 engine, which subsequently crashed in 2001 during the initial test run.
Purves was optimistic about his invention's prospects. As reported in a 1932 Popular Science magazine article, after a filmed test drive in 1932 on a beach in Weston-super-Mare, Somerset, he stated that the Dynasphere "reduced locomotion to the simplest possible form, with consequent economy of power", [1] and that it was "the high-speed vehicle of the future".

Active systems use an infrared light source built into the car to illuminate the road ahead with light that is invisible to humans. There are two kinds of active systems: gated and non-gated. The gated system uses a pulsed light source and a synchronized camera that enable long ranges (250m) and high performance in rain and snow.

A hand-power monowheel was patented in 1869 by Richard C. Hemming [2] with a pedal-power unit patented in 1885. [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.
