This page grew out of the same idea as the N-wheel car page. Four-wheel cars are common, and one-person bicycles are common. But when you start changing the numbers, you can find yourself in some interesting places...


A two-person bicycle is called a tandem, and they are not that unusual. There's one somewhere around where I live; about once a month I see a couple go by on it. There's also a one-person recumbent I see now and then.

Left: Two-person bike or tandem: 2014

Not particularly unusual, but I though at least one picture of a tandem was mandatory. This is a Rodriguez Custom Classic Touring Tandem, by R+E Cycles of Seattle, USA. The starting price is $4,699; tandems are not cheap. See more here.

This machine has derailleur gears. These can sometimes be problematic on tandem and longer bikes because of the greater cable runs make precise gear-changing harder, and it is also not possible to look down and see what gear you're in.

Left: Malvern Star abreast tandem bicycle: 1930s

A tandem is not the most sociable of affairs, with one rider staring into the other's shoulder-blades. The Malvern Star had the solution; put the riders side-by-side. Malvern's main output was conventional bikes, and they are still in business today.

Both handlebars are connected to the steering, so there'd better be good agreement about which direction to go in. Even so, keeping a bicycle upright is accomplished by making continuous small steering changes, so looks as if it might be best to have one rider designated 'Captain'.

Further research indicates that the Malvern abreast bicycle was actually a replica of a machine built in 1897 called the 'Punnett Sociable'; the replica was constructed for Malvern's 50th anniversary celebrations.

There is a short Wikipedia page on sociable (side-by-side) bicycles. An inherent problem is that wind resistance is much increased over a conventional tandem.

Left: Original Punnett Sociable abreast tandem bicycle: 1897

This is an original Punnett Sociable restored. The idea was patented by Albert Weaver of Hamilton, Ontario, and manufactured by the Punnett Cycle Manufacturing Company of New York.

You can see that between the two saddles there is another mounting for a central saddle. If there was only one of you, then you moved one of the saddles to the central position, and off you went. Or did you? You would have to use the 'wrong' pedals on each side, but more of a challenge would be steering, which was supposed to be done by grasping the two inner handgrips, which would reverse the steering. In fact the machine could be ridden with just one person on one side, as confirmed by the replica below.

There are many pictures of abreast sociable bicycles and tricycles at onlinebicyclemuseum.co.uk.

Left: Replica of the Punnett abreast tandem bicycle:

This is a modern replica of the Punnett Sociable. There are full details of the construction process here. At the end of the page is a video demonstrating that it is possible for one person to ride the machine, which has no mounting point for a central saddle, with a bit of judicious leaning to the appropriate side.

Left: Modern abreast tandem bicycle: 20??

Here is another approach to the 'sociable' tandem. Here only one of the handlebars is connected to the steering, and it also carries the brake levers and gear shift. No doubt about who's in command here.

Note the elegant way in which two sets of pedals are provided on a single frame.

Source unknown

Left: Stunt tandem bicycle: 20??

Some people just have to do things the hard way. Here the two riders are not one behind the other, but one on top of the other. Both handlebars appear to be connected to the steering.

Oviously this counts as a freak bike and is in no way practical transportation. You might have to look out for low bridges.

Source unknown

Left: Stunt tandem unicycle: 20??

So you have two riders, but who says you have to have two wheels? This unicycle presents the ultimate challenge in keeping two riders co-ordinated.

Yes, I do realise that it is a unicycle and not strictly a bicycle.

A 3-person bike is usually called a triple, though The Goodies of course called theirs a 'trandem'. Tridem and Triplet have also been used as names. Predictably, they are much rarer than tandems and a good deal more expensive.

Left: Three-person bike; the Goodies trandem: 1970s-80s

There were in fact three different triples used in the various series of the Goodies, as recorded by The Guardian.

Note the lower saddle for Bill Oddie.

Left: A conventional triple: 20??

Triples require rather more rider co-ordination than tandems do. There is some helpful advice here.

Left: Jim Gallant's Kid-First Trandem: 20??

Jim Gallent built this bike to arrange his children in order of size so everyone could see where they were going. The steering is firmly under the control of the third rider. You can see his home-built Human-Powered Vehicles (HPV) here.

Note hefty 2-inch tube along the bottom of the frame.


A 4-person bike is usually called a quad or quadruplet.

Left: A quad: 19??

Riding quads and quints is often a family affair.

Left: An unusual quad: 1948

This is clearly a freak bike rather than a practical transport proposition, but it undoubtedly carries four people.

It was reported in the 27 December 1948 issue of Life magazine, in an article titled "Hell on Wheels: Life on Mutant Bicycles" It was describing the projects of a group of Chicago bicycle enthusiasts.

It's not clear if the machine in this picture is moving or not. There is no motion blur, but a fast shutter speed would have eliminated it. There is no sign of external support to hold up the bike if it is stationary, but on the other hand there is no sign of it leaving tracks on what appears to be grass.


A 5-person bike is usually called a quint.

Left: A quint: 1950s?

Source unknown. From the clothing it might be Britain in the 1950's.

Left: A modern family quint: 20??

Note how the top tube slopes downward to the rear to allow for different heights of saddle.

The lettering on the bottom tube reads 'CO-MOTION CYCLES'


There seems to be no enthusiasm for calling a six-person bike a sext. Can't think why.

Left: Six-person bike: 2014

This custom 6-person bike was built by Steve's Bike Shop in Altadena for CBS, to air in a commercial for their new fall line up.

Left: Six-person bike: 2014

This custom 6-person bike was built for family outings.

There appear to be auxiliary chains fitted so that the younger offspring have pedals they can reach, and so can deliver their quota of horsepower. R+E Cycles make a kit for this called the Kidback.

On Sunday, August 23, 1970, the St. Paul Sunday Pioneer Press, Wisconsin News, published the following article: "30,000 DUE AT STRUM FESTIVAL."

"This is the famous SEVEN MAN BICYCLE......a major attraction at community parades around the Strum area and west central Wisconsin. A Strum product! Built in Strum by Jewel Berge, our Blacksmith, and crew.

"This bicycle also appeared in the Fall 1964 Homecoming parade at the University of Minnesota. I was a student and resident of Frontier Hall Dormitory. I convinced my father to let me bring it to Minneapolis, that I had the guys in the dorm that could ride and manipulate this monster of a bike. Maybe a week before homecoming my friends and I and a Corvair with hitch made the trip to Strum, hooked up the bike and specially built trailer and made the trip back to Minneapolis. The stares along the way through Eleva, Mondovi, Durand, Prescott and then through the St. Paul-Minneapolis Metro area on U.S. Hiway 10........the stares were unreal!"

"Once we found a parking place for the bike back of the dorm, it was the local attraction around the dorm and Minneapolis campus for days. And then we practiced and the attraction grew. The bell, the air horn fed by that tank on the back of the bike.. A hit as you can imagine."

"This bike and our 7 guys, me being one, were the Frontier Hall entry in the Homecoming Parade. The parade angled down University Avenue on the Minneapolis Campus.....and we snaked this bike along the way, working hard to keep the back wheel on the center line and veering left and right with the front. It worked. We won first prize for all dormitory entries in the parade..........and the stares and hoots never quit!"

"What a great idea my fellow Strumites (or is it Strummers) had for promoting Steam Engine Days....and just about anything! Put a candidate for local or state office on something like this and the voters would never forget the person, just like the memory no doubt caused many a parade goer to never forget this entry in the parade and the NEED to get to Strum on Steam Engine Days each year."

"NOTE: my father, Roy Matson is the second man from the left in this picture. All of these men are well known in the Strum area. In this picture, they obviously are riding in a parade (probably other than Strum) to promote the upcoming Steam Engine Days probably during the mid to late 1960's."


Left: Eight-person bike: 2014

This bike was found on the website of Lancashire Limousines who would like to sell it.

The website has a video of the machine in action, though sadly only with five riders.

There was once a giant 8-person tricycle, built to promote tyres.

Another picture of the 8-person bike above.


Left: Nine-person carousel bike: 2003

Finding a nine-person bike was never going to be easy, and so this is the best the Museum Staff can do for the time being. The Circular Bike was fabricated from nine salvaged bikes by Robert Wechsler in spring 2003.

Yes, I have noticed that it is not strictly a bicycle as it has nine wheels.

The bike is 3 ft high by 12 feet in diameter; it is modular and can be dismantled, transported and reassembled. It is normally left in public places to attract can attract riders and spectators.

You can see more pictures here.

Left: The BusBike: Nine-person six-wheel 'bike': 2014

The BusBike was fabricated from nine salvaged bikes By Cleveland Motley.

And yes, once again I have noticed that it is not strictly a bicycle as it has six wheels. You will have to live with the fact that when you get up to nine people, the rules are going to get bent a bit.

The machine has Ackermann steering, as used on cars.

You can see more pictures here.


Left: The Oriten ten-person bike: 1896

This ten-person bike was built by Charles Metz of Massachusetts in 1896 to promote his 'Orient' bicycle factory. (Oriten is an anagram of Orient) It is in the Henry Ford Museum.

The bike is 23 feet long and weighs 305 pounds. It was reported to be very hard to ride. It could reach 45 mph, which required some courage as it had no brakes, nor indeed gears.

Bracing wires can be seen running diagonally downwards from rear to front. The bracing was to improve lateral rather than vertical stiffness.

This machine is fairly well known.

Left: The Unicycle Factory ten-person bike: 2010

If you thought the Oriten was a singular aberration, think again. The Unicycle Factory built this 10-person bike. There are hydraulic brakes on the front wheel.

I am aware there are two wheels at the back, but as with nine-person bikes you have to be a bit flexible. Stability at parade speed was the problem, solved by the two rear wheels.

You can see more at sillycycle.com, and there is a YouTube video of it in action. (uploaded June 2010)

Left: The Unicycle Factory ten-person bike: 2010

Another view. Note the large top tube, which appears to be about 4 or 5 inches in diameter. The top tube is in compression rather than tension, and so needs to be strong enough to resist buckling.

The frame has been repainted at some point.

Image quality poor, I'm afraid.

Left: Unidentified ten-person bike: date?

Found on the Interwebs. Can anybody identify this machine?

Note the extra bracing. It looks intended to improve lateral rather than vertical stiffness, as in the Oriten above.

Left: The twenty-person bike: 2015

This monster machine is currently the record holder in the Guiness Book of Records. The frame is a big triangular girder, to obtain sufficient rigidity. The bike had to be ridden a distance of 100 metres without stabilisers to prove that it is "rideable" and so qualifies for a Guiness record. To make this possible the rear 'wheel' is more of a giant roller. The machine is 136 feet long.

It was built in 2015 by the University of South Australia, with support from the gas and oil company Santos.

There is an intriguing video of this monster on YouTube


Left: Possible forty-person bike:

This image comes from the Velovision website. The link on that site only goes to a 'not found' page in Japanese.

Whether this is a real machine or a Photoshop job is currently unknown. However, details like the bell on the handle bars and the extensive frame underneath that keeps the machine standing up incline me to think it is is real.

This website gives a length of 26 metres and confirms that there are forty seats on the machine, but no other information is given.

The Museum Staff are investigating, but I can tell you now that Googling 'forty-person bicycle', and variations thereon, yield nothing relevant.
