SMZ S3A Soviet SMZ Cycle Microcar USSR 1957 Year 1/43 Scale Diecast Model Car

The SMZ cycle car was a Soviet microcar, manufactured in Serpukhov, Russia by Serpukhov Motor Works, now SeAZ. The most common models were the S-3A (S-Three-A) and S-3D (S-Three-D). They were specially designed for disabled drivers and were distributed in the USSR for free or at a large discounts through the Soviet Union's social welfare system, and were not officially sold to non-disabled people.

The S-3A-M was produced between 1958 and 1970. It was powered by a 346 cc single-cylinder two-stroke engine giving 10 hp (7 kW) and a top speed of 55 km/h (34 mph).

S-3D, produced between 1970 and 1997, was a twin-seat, four-wheeled cycle-car, 2.6 metres (102.4 in) in length, but rather heavy (~500 kg) due to all-steel body. It was powered by IZH-P3 air-cooled two-stroke engine (18 DIN hp).

In the USSR they were commonly known as "motor-wheelchairs" (Russian: инвалидка), because they were only leased via social care system to disabled people for five years without permission to sell, just like the British Invacars, made by AC, Thundersley and Tippen. After 5 years of use, a lessee had to return his "motor-wheelchair" to social care organisations, and was given a new one.
