What the number itself says

Reading RPCGC.150PGB left to right: R is the model-year letter for 2024, PCG is the three-character code the EPA assigned to Peace Industry Group (Usa) as certificate holder, C marks a highway (street-legal) certification, .150 is the displacement in litres, so 150cc and PGB is Peace Industry Group (Usa)'s own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.

The engine, as described on the certificate

The test vehicle Peace Industry Group (Usa) submitted for this family (model RY150T-3) carried engine code 157QMJ. In the Chinese engine-model convention that reads as one cylinder with a nominal 57 mm bore, QMJ series. Against the certified 149.6cc that implies a stroke of roughly 59 mm — a sanity check for a piston or cylinder listing, not a published figure.

The certificate describes a four-stroke, single-cylinder engine with 2 valves per cylinder fed by carburettor. There is a catalytic converter in the exhaust, recorded as "TWC, single bed, open loop". The head carries a pulse secondary-air (PAIR) valve.

Rated power on the record is 6.3 kW (about 8 hp) at 7,500 rpm, driving through an automatic.

Filing history and where it was sold

Peace Industry Group (Usa) filed one certificate under this family, for model year 2024, sold as 49-state (not certified for sale in California).

The vehicle itself is recorded as built by Zhejiang Riya Motorcycle Co., Ltd. in China, while the engine came from Taizhou Xinba Power Manufacturing Co., Ltd. Chassis parts and engine parts therefore have different origins.

Certified emission levels: CO 6.6, HC 0.3 g/km.

Other records carrying the same engine code

Peace Industry Group (Usa) certified an engine with this code under 5 other family numbers — the same engine filed again in another year, or in an off-road and a street version:

  • FPCGC.150S4A (2015)
  • LPCGC.150PGB (2020)
  • MPCGC.150PGB (2021)
  • NPCGC.150PGB (2022)
  • PPCGC.150PGB (2023)

Other certificate holders whose test vehicle carried the same engine code (10 of 46 shown):

A shared code from the same factory is a strong search lead. From a different factory it is as often a naming coincidence. Either way it narrows the search; it does not settle it — measure before you buy.
