JAKE LYALL AND THE RIOT WHEEL

Left: Jake Lyall's RIOT wheel at the 2003 Burning Man Festival.

This chunky 1100-pound machine is Jake Lyall's RIOT (Re-Invention Of The) wheel. Lyall's monowheel is unusual because it does not use the rider's weight to provide the reaction to the engine's thrust on the wheel. Instead the rider is outside, and the reaction is given by a lead-weighted Honda 80cc 4-stroke scooter engine suspended from a central shaft, driving through a sprocket attached to the wheel spokes. A separate 450-pound counterweight keeps the rider hovering above the ground at the front. Steering is done partly by precessing a 65-pound gyroscope to give yaw, and partly by the rider shifting his weight.

Left: The internals of the RIOT wheel.

A. Chassis, MIG-welded out of thin-walled steel tubing.

B. Spring-mounted seat tilts 15 degrees each way.

C. Throttle controls engine speed; joystick controls gyro and counterweight crane to lift or lower the driver.

D. 80cc four-stroke Honda scooter engine and 80 pounds of lead, delivering 120 pound-feet of torque at 90 degrees forward.

E. Sprocket bolted to outer spoke transfers engine assembly's torque to wheel.

F. Disc brake bolted to outer spoke; in full-skid braking, engine assembly is pulled backward from 0 degrees, pushing the driver quickly but safely to the ground, where a skid plate on the bottom of the seat aids braking.

G. 450-pound counterweight system, which works even without the engine inside.

H. 65-pound steel gyro, powered by two fan motors, tilts on a horizontal axis to yaw the vehicle for steering.

I. 1.5-gallon gas tank. Future versions will be electric.

J. 20-inch-wide rimless tire.


THE SCRAPHEAP CHALLENGE MONOWHEELS

The Scrapheap Challenge is a UK television series in which two teams compete to build unconventional machinery- usually some sort of strange vehicle. One of the challenges was a monowheel, and both Kerry Mclean and Geraint Evans were involved. The competition was on 3rd Nov 2002. Two monowheels were built; the one with the fat wheel on the left was the winner.

Built by the Hammerlocks team
This was the winner

THE KEITH DUFRAYNE MONOWHEEL

This superb picture was kindly provided by Keith Dufrane. He says:

"I became fascinated with them a few years back and made one based on a 100cc Honda trail bike engine. I dress up as Uncle Sam and take in a variety of parades in Columbus, Ohio, each summer."


A RUSSIAN MONOWHEEL: THE SUNCYCLE

Left: Russian Foot-Powered Monowheel.

This picture was provided by Valery Makarenko. Apparently you scoot along, standing on the small platform at the bottom, and holding onto the two angled arms. A purist might argue that this doesn't count as a monowheel as the rider is not actually inside the wheel, but I for one am prepared to give it the benefit of the doubt.

The Suncycle is a commercial venture currently seeking funding for mass production.

A BRAZILIAN MONOWHEEL

The Wheelsurf is being actively marketed at present. It appears that plastic mouldings are used for the frame, so a significant amount of money has been invested in the project.
The project now seems to be based in Holland.

A CHINESE MONOCYCLE

Li Yongming, left, and Zheng Jun demonstrate commercial monocycles during a promotion in Beijing in 2003 (?). The monocycle was designed and built in Xian in China's Shanxi province, and is said to sell for 2,888 Chinese yuan (approx $350).


THE STEAMBOY MONOWHEEL

Connoisseurs of these pages will have wondered if anyone has taken the obvious step of building a steam-powered monowheel. The answer, sadly, appears to be no, but here is a fictional one.

Left: The Steamboy Monowheel.

Ray Steam on/in his steam monowheel is hotly pursued by a steam-powered villain.

This is an anime production by Katsuhiro Ôtomo, the maker of "Akira". Learn more at: sonypictures.com/movies/steamboy/

This film is, and I quote: "A retro science-fiction epic set in Victorian England. Steamboy features an inventor prodigy named Ray Steam who receives a mysterious metal ball containing a new form of energy capable of powering an entire nation." It is an excellent piece of entertainment, with lots of style and some stunning visuals, but it has to be said that its grip on thermodynamics is tenuous at best.


THE DAVID SOUTHALL MONOWHEEL

Left: The David Southall Monowheel.

This fine machine has been recently built by David Southall. It is called The Red Max. David says its construction was inspired by the 1924 circus monowheel on this website, no less.

David has now kindly provided more details:

"The wheel itself is a 5 foot diameter hoop of 2 inch tube. It was a bit beyond what I can do so was made for me by The Angle Ring Company . The pulleys on which it runs were custom-made by AED rollers. Everything else was cut, bent and welded in my shed!

The engine is a 90cc four stroke from a Chinese quad bike. I was initially going to use the engine/wheel unit from a 50cc scooter but the wheel was too big and the two stroke power delivery can be a bit ‘peaky’! The quad engine is fully auto with electric start. The friction drive wheel is the rear wheel from a mini moto. It has a cable-operated disc brake which must be used with extreme caution. The tyre on the outer wheel is three 24 inch mountain bike tyres cut up and pop riveted on. Once I had all the major parts the actual build only took eight days.

The handling is quite good, although I have nothing to compare it with! It is relatively easy to get your feet up providing you have achieved a certain speed. I am unsure of the top speed of the machine but have easily won a race against a lad who was sprinting a quite a pace. I will try to attach a pushbike speedometer and get some figures in the near future."

See Dave's impressive website (including videos) here.


THE WIM TE KAAT MONOWHEEL

Left: The Wim te Kaat Monowheel.

This monowheel was built solely from some pictures found in a museum somewhere in the France. The first riding trials were made in March 2007

Mr Wim te Kaat lives in a small village called Silvolde in the east of Holland.

This monowheel appears to be powered by hand-crank. Hopefully there will be more technical data soon.

THE CHILEAN MULTIWHEEL

Left: Multiwheel at Chilean music festival

Musicians perform inside a four-meter-high metal wheel as part of Chile's 21st annual international street festival. This is best seen on YouTube: Festival in Chile

"Monowheel" hardly appears appropriate for this creation, which appears to be powered by geared penny-farthings on each side of the main central wheel. Inside that wheel three musicians swing around in their own individual "monowheels". As the YouTube video shows, the machine can move forward (the headlight is a nice touch) or pivot on the spot.

Quite remarkable! Well done to all concerned.

Drawn to my attention by Ben Burch- many thanks


THE TOM ANABLE MONOWHEELS

Left: The Land Speed Monowheel

Tom Anable is a prolific builder of monowheels in England.

This monowheel by Tom Anable took the British monowheel top speed record on 18th of August 2013 at Elvington Airfield, York. It reached a land speed of 60.1 mph. It is powered by a 200cc petrol engine.

Tom has a website here

There is now a British Monowheel Association, whose members include Dave Southall and Tom Anable.


WHY MONOWHEELS?
Why did these remarkable machines appear between the wars? My own guess was that the technology derived from the strategic bombers that emerged at the end of WW1, such as the Handley-Page 0/100 and V/1500 machines. These gigantic biplanes had proportionately large wheels, requiring enormous tyres. These tyres were presumably cheaply available when this type of bomber became obsolete, and could have triggered the idea of driving around inside them.

However, the discovery of The Monocycle Garavaglia of 1904, rather knocks a hole in this brilliant theory...


A BAND CALLED MONOWHEEL
A musical ensemble appeared called "Monowheel". They had a webite at www.monowheel.com but as of Nov 2014 the site had vanished and the domain name appears to have been put up for sale.

However, this download site suggests that the music, if not the band, still exists. They do not appear to be on YouTube.
