Source-derived summary

Duocars Ltd of 70 York Street, London was a maker of cycle cars founded in 1910. The cars were built in Alpha Street, Deptford, London. The company was founded by Mr L.F. de Peyrecave.

The name Duocar is easily confused with the generic name 'duocar' used at the time to refer to two seater cycle cars (single seaters being called 'monocars'), and possibly for this reason the Duocars are sometimes referred to as Duo cars, Duo cyclecars, or Duo cycle cars. Mr de Peyrecave was quite successful in promoting his cars, getting four of them on the front cover of the first edition of The Cyclecar magazine in November 1912.

The Duocar was also reviewed in the Forgotten Makes series of Motor Sport magazine in 1994, which noted some of the many records held by the Duo (notably those gained at Brooklands in October 1912), and the endurance events in which the Duo competed.

The Duocar was described at the 1912 Motor Cycle and Cycle Car Show, with a JAP 8 hp V-twin providing the power, with fan assisted cooling. A large diameter external flywheel was fitted to smooth the engine which was fed by a Lukin carburettor operated by an accelerator pedal. The steering had a cable and worm drive. It used Hans Renold chain drive to the countershaft, and the drive to the rear wheels was by 1.125inch armoured V-belts.

Editorial analysis

Why this record matters

“Duocar” is worth following because a concise public description often conceals a longer documentary argument. Here, Duocar, Open-knowledge and entry provides the most credible route into that argument.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Oct 15, 2025. The linked authority identifier is Q20973682. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1910, 1912 and 1994.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
