Which Jiajue U.S.A. models have a Chinese-built engine?

What the Jiajue U.S.A. filings say about the engines

Jiajue U.S.A.'s filings mix carburettors and fuel injection: 24 rows carburetted, 1 injected. The first injected family appears in 2024; in 2026 the split was 2 carburetted to 0 injected. Check which you have before buying anything on the fuel side.

The engine codes on Jiajue U.S.A.'s test vehicles —4 distinct across the filings — are led by JJ1P39QMB, JJ1P61QMK, JJ157QMJ and JJ1P39QMB-A. The code is stamped on the crankcase and is a better search term than the badge.

3 of the 25 filings are 50-state (California-legal); the other 22 were 49-state only.

Rated power across the range runs from 1.9 kW to 7.6 kW (about 3 to 10 hp).

The vehicle builders named are Zhejiang Jiajue Motorcycle Manufacturing Co.,Ltd and Zhejiang Jiajue Motorcycle Manufacturing Co., Ltd. — the chassis and the engine do not always share a source.

Each figure is read straight off the EPA certificate rows; the per-family pages below carry the full breakdown for every engine family.
