Briggs & Stratton Flyer

Also known as Smith Flyer, Auto Red Bug, Red Bug

No springs, no gearbox and no reverse: a platform of wooden slats on four small wire wheels, pushed along by a fifth wheel with its own engine. Guinness lists this American cyclecar as the cheapest car ever sold, and its engine led Briggs & Stratton to garden machinery.

True proportion

2.34 m

It is 633 mm shorter than a Fiat 500, about 1.3 adults laid end to end.

Drawn at true proportion. The track is 3.6 metres long; the adult stands at the same scale. The Peel P50 is the smallest production car, on every page for comparison.

The story

History

To drive off in a Flyer, you first lifted the fifth wheel clear of the road with a lever, spun it by hand to start its engine, then lowered it onto the ground and let it push. The lever was the whole transmission: lift the wheel and the car stopped driving.source 5source 1source 6 Reverse was a matter for the driver’s feet.source 6

Reverse? Dig in a heel and push.

John Matras, driving a 1920 Briggs & Stratton Red Bug, AutoWeek, 2 January 1989.source 6

A wheel for a bicycle

The Flyer was a car built around a bicycle accessory. About 1910 the Englishman Arthur William Wall, of Birmingham, devised a self-contained wheel with its own engine, to push a bicycle along.source 7source 2 In Britain it was sold as the Wall Auto-Wheel, built, one source says, by BSA.source 8 In 1914 the A. O. Smith Company of Milwaukee bought the American rights; AutoWeek says Smith saw the wheel on holiday in England.source 7source 2source 6 Smith changed the drive: where Wall’s wheel was spoked and driven through a 4:1 chain, Smith’s was a 508 mm (20 in) disc driven straight off a four-lobe camshaft turning at one-eighth of engine speed, and its inlet valve was atmospheric, sucked open by the piston. The bright red Smith Motor Wheel went on sale in October 1914 and sold well enough for Smith to open a new plant; AutoWeek puts its sales in the thousands by 1918.source 6

The Smith “Flyer”, 1916

In 1916 the wheel was hitched to the back of a wooden buckboard.source 5source 1 The platform of hardwood slats was chassis, body and suspension at once: there were no springs, the slats flexed over the bumps, and the only padding was in the two bucket seats.source 6source 2 The fifth wheel trailed between the rear wheels, carrying its engine and its fuel tank with it.source 5source 1source 3 Popular Science later noticed that it steered like a child’s coaster wagon, the whole front axle pivoting on a single bolt.source 3

The A. O. Smith Company, Milwaukee, Wis., has recently perfected a light, economical, two-passenger motor vehicle known as the Smith ‘Flyer.’ In summer it can be run on wheels as a comfortable and easy-riding buckboard and on runners in winter as a safe, speedy motor sled.

Hardware Age, 11 November 1916.source 5

The trade press gave the details in the maker’s own terms. The car weighed 61 kg (135 lb) complete, ran on wire wheels of 508 mm (20 in) with double-tube clincher tyres, reached 32–40 km/h (20–25 mph) and covered 80 to 90 miles on a US gallon, about 2.6–2.9 litres per 100 km. There was a thumb throttle on the steering wheel, one control lever, a clutch and a foot brake, and the clutch lifted the motor wheel about 25 mm (an inch) off the road. The seats were upholstered in tan, the body left in natural wood, and the fittings nickel-plated. It cost $125, free on board at Milwaukee.source 5source 1 Other advertisements of 1917 asked $130 or $135.source 7source 9

Who first built the buckboard is not settled. The trade press of 1916–⁠17 names only Smith. AutoWeek says the Automotive Electric Service Corporation of North Bergen, New Jersey, first fitted a Smith wheel to a buckboard in 1916, and that Smith then supplied the wheels while the New Jersey firm built the rest. Kimes says it began that year as the Red Bug of the American Motor Vehicle Company of Lafayette, Indiana.source 5source 1source 6source 4 Some accounts date the Flyer to 1915, others to 1917; the trade press shows it new in November 1916.source 7source 10source 5 Notices for Smith Flyers appeared in Shanghai and Hong Kong newspapers in 1918–⁠19, and an owner in South Perth, Western Australia, registered one in 1925–⁠26.source 11source 12

Briggs & Stratton, 1919

In 1919 Stephen F. Briggs and Harold M. Stratton’s company bought the rights to the Motor Wheel and the Flyer.source 6source 4source 2 It gave the engine a larger bore, 63.5 × 63.5 mm (2½ × 2½ in) or 201 cc, an all-steel connecting rod and a flywheel magneto, raising the power from about 1.5 hp to 2 hp.source 6source 2source 13source 3 In 1919 the firm made automotive electrical parts; the lawn-mower engines came after the Flyer, so the popular caption calling it a car from a lawn-mower maker gets the order backwards.source 6source 13

Briggs & Stratton sold the Flyer across the country, and pitched it at boys.source 2source 14 In Youth’s Companion in April 1920 an advertisement headed “His Own Car” offered a free booklet, Motor Wheel and Flyer.source 14

The Briggs & Stratton Flyer is the boy’s car, created for red-blooded youngsters whose greatest hope is to sit behind the wheel and GO.

Briggs & Stratton, advertisement “His Own Car”, Youth’s Companion, 15 April 1920.source 14

Another advertisement, as AutoWeek quotes it, had older customers in mind.source 6

Just imagine riding over 80 miles on one gallon of gasoline, at a rate of between four and 25 miles an hour, along some delightful boulevard or over a picturesque country road with a charming young lady for a companion.

Briggs & Stratton advertisement, as quoted by John Matras in AutoWeek, 2 January 1989.source 6

Every car was red, and around 1920, by AutoWeek’s account, the name became the Auto Red Bug; Kimes lists the 1921–⁠23 model as the Red Bug, Model D Buckboard.source 6source 4 By 1923 the Ford Model T was closing in. A new Model T roadster cost $260 in 1925, and a used one much less; the Lane Motor Museum notes that a 1924 Model T, at $265, cost more than twice as much as the Flyer.source 6source 15 Briggs & Stratton dropped the motor wheel, cut the “horns” off its engine and fitted it to a garden cultivator. AutoWeek and Wikipedia treat that as the start of the company’s small-engine business.source 6source 2 It sold the buckboard rights to the Automotive Electric Service Corporation in 1924 by Kimes’s and RM Sotheby’s account, in 1925 by Wikipedia’s.source 4source 16source 2

The Red Bug, 1924–⁠30

At North Bergen the buckboard carried on as the Red Bug, or Auto Red Bug. It was built with petrol motor wheels until the supply ran out, and then as an electric car, on four wheels only, with a Northeast motor driving one rear wheel; Wikipedia says it was the motor that started contemporary Dodge Brothers cars.source 4source 2source 17 Motor Age described it in May 1927, sold by Automotive Standards, Inc. of New York from the factory at North Bergen: two 6-volt batteries and a series-wound motor geared to the right rear wheel, 13–16 km/h (8–10 mph) and a range of 32–48 km (20–30 miles), or 26–29 km/h (16–18 mph) with an optional 16-volt battery. It had an electric horn, two headlamps and a tail lamp, red wheels and mudguards on varnished wood, and it cost $300.source 18 The Lane Motor Museum gives the rights-holder the same name, Automotive Standards.source 15

Abercrombie & Fitch sold Red Bugs in the United States, and they were also sold in Britain and France, mostly as novelties for the wealthy and as transport at resorts and amusement parks.source 17source 15 The Lane Motor Museum says Ettore Bugatti bought one for his son Roland.source 15 In 1930 the Indian Motocycle Company was reported to be taking it over, but did not.source 17 When production ended is uncertain: 1927, 1928 and 1930 are all given.source 15source 19source 4

How many Flyers and Red Bugs were made is not known. Thousands of motor wheels were sold, for bicycles as well as for cars, but no count of the cars themselves has been found; in 1960 Popular Science found the records vague, though it thought the number must have been substantial.source 6source 3

Famous for

Three points

  1. Five wheels

    Four to carry it and a fifth, with its own engine, to push; lifting it was the clutch.

  2. No springs

    The slatted wooden platform was chassis, body and suspension; the seats had the only padding.

  3. The lawn-mower link

    When the car trade faded, Briggs & Stratton put the motor-wheel engine on garden machines.

Racing and records

In the record books

No race entry for the Flyer is known; its records are entries in the Guinness books (more in records and feats).

$125
The cheapest car ever sold, as Guinness lists it, on a 1922 price of $125–150 for the Briggs & Stratton Flyer. The title belongs to the petrol buckboard: the electric Red Bug cost $300 in 1927.source 2source 15source 18
1917
The first five-wheeled car, in the Guinness Car Facts & Feats; later editions call it the most successful five-wheeler.source 10

Survivors and collecting

Today

In 1960 Popular Science spent a year looking for Flyers and found only seven, fully or partly restored, nearly half of them hybrids of Smith and Briggs & Stratton parts. Many bodies and wheels survived separately, because the wheel had also been sold for bicycles. That year F. P. Stratton owned one himself; the company had none. The singer James Melton showed one at his “Autorama” in Florida, then sold it to a collector in Reno, Nevada, and built a replica. A New Jersey family had used theirs for daily transport under petrol rationing in the Second World War.source 3

A Smith Flyer replica, dated 1915, and an Auto Red Bug of 1924 are in the Lane Motor Museum’s collection, both fitted with period Aerothrust propeller engines.source 7source 15 A 1920 Briggs & Stratton Flyer was pictured in Harrah’s Automobile Collection, and one appears in a museum directory of 1992.source 20source 21 Kimes’s guide of 1996 valued the Flyer and the Red Bug at $1,500 to $11,000 by condition.source 4
