A 
microcar is the smallest automobile classification, usually 
applied to very small cars (smaller than city cars). Such small cars 
were generally referred to as cyclecars until the 1940s. More recent 
models (1960 and later) are also called bubble cars due to their 
bubble-shaped appearance.
The heyday of these cars was 
surely in the mid- to late 1950s, when post-war Europe turned to 
creating mobility solutions for the masses. The original Mini and Fiat 
500 may be the most recognisable machines, but we present our choice of 
ten of the 
most unusual microcars from this era:
Peel P50

The 
Peel P50 is a three-wheeled microcar originally manufactured from 1962 to 1965 by the 
Peel Engineering Company
 on the Isle of Man. It currently holds the record for the smallest 
automobile to go into production. It has no reverse gear, but a handle 
at the rear allows the very lightweight car to be physically maneuvered 
when required.

Designed
 as a city car, it was advertised as capable of seating "one adult and a
 shopping bag." The vehicle's only door was on its left side, and 
equipment included a single windscreen wiper and only one headlight. 
Standard colours were Daytona White, Dragon Red and Dark Blue. The 1963 
model retailed for £199 when new (about £1,400 in 2010, or $2,200 USD). 
50 of them were produced, and only 27 of them are known to be still in 
existence. [

Allard Clipper
image source
The 
Allard Clipper was first created in the UK in 1953 by the sports car maker 
Sydney Allard.
 Despite winning the 1952 Monte Carlo Rally in a sports car of his own 
design, the sales of Allard sports cars were swamped by manufacturers 
like Jaguar and so Sydney Allard decided to design an economical car. 
The Allard Clipper was designed by David Gottleib and had an 
"indestructible" plastic body that was made by Hordern-Richmond Ltd. 
This made it the first car to have a plastic body. It was powered by a 
346cc Villiers twin engine that powered one of the rear wheels.
image source
Unfortunately
 the Allard Clipper was to suffer from many problems that included 
cooling and weak drive shafts and so manufacture ceased in 1955 after 
only about twenty vehicles were made. It is believed to date that only 
two vehicles still exist. [

Isetta

The 
BMW Isetta
 is among the most iconic microcars, but was not developed by the German
 automaker. Refrigeration magnate Renzo Rivola saw an opportunity to 
create the small economical car he yearned for, acquiring the patents 
for a design that would become the Isetta – diminutive of Iso, the name 
of his company.

At just over two metres long, the egg-shaped 
Iso Isetta
 was unique in having a single door on its front, to which the steering 
column and instrument panel were attached. Early models were 
three-wheelers, but a fourth wheel was later added for stability. Its 
236cc two-stroke engine produced all of 9.5 horsepower, comparable to 
the output of riding lawnmowers of today. [

Messerschmitt KR200
The 
Messerschmitt KR200, or 
Kabinenroller (Cabin Scooter), was a three-wheeled bubble car designed by the aircraft engineer 
Fritz Fend and produced in the factory of the German aircraft manufacturer Messerschmitt from 1955 to 1964.
The
 three-wheeled KR175 (and later KR200) was powered by a single-cylinder 
two-stroke engine and coined the bubble car because of its jet-like 
canopy. Officially known as the 
Kabinenroller, it sat two in 
tandem and featured an oversize steering wheel more suited to aircraft 
than passenger cars. Its interior was rudimentary at best – the only 
instrumentation was a speedometer. [

Scootacar
1959 Scootacar Mk 1 [image source]
Scootacar
 was a British three-wheeled microcar built in Hunslet, Leeds by 
Scootacars Ltd a division of the railway locomotive builder, the 
Hunslet Engine Company between 1957 and 1964.
image source
It
 was allegedly built because the wife of one of the directors wanted 
something easier to park than her Jaguar. The shape of the car was 
designed by 
Henry Brown who did it by sitting on a Villiers 
engine and then having an assistant draw an outline around him. The body
 was built in glass fibre and was very tall for its size being 60 in 
(1,524 mm) high, 87 in (2,210 mm) long and only 52 in (1,321 mm) wide. 
It was nicknamed "
the telephone booth". Two people could be 
carried with a passenger behind the driver or alternatively just 
squeezed in alongside. Power came from a Villiers 9E 197 cc single 
cylinder 2 stroke engine coupled to a four speed motorcycle type gearbox
 and chain drive to the single rear wheel. Steering was by handlebars. 
The top speed was 
50 miles per hour (80 km/h). [

Paul Vallée Chantecler
Built by 
Paul Vallée, a wealthy industrialist who foresaw the need for scooters in post-war Europe, this three-wheeled microcar was cloaked in a 
streamlined, teardrop-shaped fibreglass body created by the founder of the Ecurie France racing team.
The
 interior featured a bench seat and a D-shaped steering wheel to ease 
access. Equipped with an inertial Gyrostarter system derived from 
helicopters to start the two-stroke, single-cylinder 125cc engine, the 
car was mercifully less successful than Vallée had hoped. Only 200 were 
built before he turned his attention toward a more profitable venture – 
buying into a Rolls-Royce and Ferrari dealership. [

 Autonacional Biscúter 100
image source
The
 car had its origins in France in the late 1940s, where aircraft and car
 designer and manufacturer Gabriel Voisin had designed a minimal car 
called the 
Biscooter for Avions Voisin. The playful name implied 
that it was about the size of two motorscooters, or a scooter with four 
wheels. The design drew no interest from either manufacturers or 
consumers there, however, and he eventually licensed it to Spanish firm 
Autonacional S.A.
 of Barcelona. By the time it was introduced in 1953, the marque had 
been hispanicized to Biscúter. The first car had no formal model name 
and was called simply the Series 100, but it soon became known as the 
Zapatilla, or little shoe (clog), after a low-heeled peasant slipper popular at the time.
image source
The
 Zapatilla
 was minimal indeed, with no doors or windows or reverse gear. The 1 
cylinder, 197 cc, two-stroke motor produced 9 horsepower (7 kW), had a 
crank starter, and drove only the right front wheel. Braking was by an 
unusual three-point system involving the transmission and cable ties to 
the two rear wheels. One genuinely advanced feature was an all-aluminum 
body, although steel was later used. [

1951 Reyonnah
image source
The prototype shown by 
Mr. Hannoyer (Reyonnah backwards)
 at the Paris Salon of 1950 evolved over the next few months to a 
definitive production form. The open "torpedo" body tub with the 
sweeping curved cowl and sides, became a convertible with a side-hinged 
top mounted on the now straight sides. The windshield no longer folded, 
the headlamps were deeper, rear fenders flatter, and wheels 
(from the Simca Cinq) changed in pattern. Different lifting tops were seen, including canvas soft tops, hardtops with sunroof, and clear bubbles.
image source
 
This
 fascinating car sacrifices ergonomics for design, however. It is 
difficult to imagine a lady in a '50's tight skirt clambering over the 
tall sides into the tub. The large steering wheel and controls are 
stuffed into a cramped knuckle-bruising space under the front cowl. And 
finally, its front suspension "trick" does not allow for a lock in the 
"up" position, so that moving the car forward with suspension "up" 
causes it to collapse back to "down", defeating its purpose of rolling 
it into a tight spot like a motorcycle. [

Daihatsu Bee
The 
Daihatsu Bee is a three-wheeled microcar produced by the Japanese manufactuer Daihatsu from 1951.
image source
Although
 Daihatsu had been producing motorized tricycles for carrying freight 
since 1930, and had also produced a small car for military use in 1937, 
the Bee was the first passenger car the company built for sale to the 
general public. The car was marketed from October 1951, shortly before 
the company changed its name from 'Hatsudoki Seizo Co' to Daihatsu.
image source
Photographs
 show the car with a two-door fibreglass body, though other sources 
state that it had a four-door body instead and as a result was popular 
as a taxi. Power was provided by a rear-mounted 540 cc OHV air-cooled 
two-cylinder four-stroke engine. It was the first car in Japan with a 
horizontally opposed engine. The car was adapted from one of Daihatsu's 
three-wheeled delivery trucks. It sold very poorly, production was 
highly labor-intensive and ceased after only approximately 300 units 
were built.

1955 Inter 175A Berline
image source
With
 its strong avionic design cues, it shouldn’t surprise that this 
microcar was actually built by the national aeronautic society of 
northern France. Arguably the most attractive of the three-wheelers, the
 Inter featured a single headlamp in its fuselage-inspired body and a 
hinged canopy that included glass windows.
image source
It
 also introduced a number of innovations, such as a folding front 
suspension and a Gyrostarter system, which employed a small electric 
motor and a flywheel to crank-start the engine. Only 280 were built, and
 no two cars were ever exactly alike. [
