A monowheel or uniwheel is a type of one-wheeled, single-track vehicle. Unlike the unicycle , a monowheel consists of a large, hollow wheel that loops above and around the driver. Monowheels are typically powered by an engine as with a motorcycle , with a chassis securing the steering, driver's seat, and propulsion mechanism to the interior of ...
The first monowheel tractors appeared in the 1920s, as a result of technical developments in small petrol engines. These had been driven by improving engine technology, particularly for motorbikes. Such engines now represented an affordable and portable power source.
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".

The world's first multi-stage unicycle race, Ride the Lobster, took place in Nova Scotia in June 2008. Some 35 teams from 14 countries competed over a total distance of 800 km. [ 42 ] Each team consisted of a maximum of 3 riders and 1 support person.
Early Auto-Truck, with small wheels. The Lister Auto-Truck was a small monowheel tractor built for moving light loads around factories, railway yards and similar sites. They were based on a design originally by Auto Mowers Ltd, and were built by R A Lister and Company of Dursley, Gloucestershire, well known for their range of small stationary engines (although the Auto Truck used a J.A.P ...
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.

The pilot has an enclosed cockpit with a Plexiglass canopy and the landing gear is a non-retractable, unsprung monowheel with a tailskid. [1] [2] [5] The SB-5 prototype first flew on 3 June 1959. A licence to build it went to Firma Eichelsdörfer at Bamberg, who produced more than 100 including all variants. [2]
