What the Maxtrade filings say about the engines
Every Maxtrade filing on record is carburetted — 76 certificate rows, 2008 to 2026, and not one fuel-injected engine among them.
The engine codes on Maxtrade's test vehicles —11 distinct across the filings — are led by M4A1, M1A1, M5A1, M3A1 and 120M1A. The code is stamped on the crankcase and is a better search term than the badge.
59 of the 76 filings are 50-state (California-legal); the other 17 were 49-state only.
Rated power across the range runs from 3.4 kW to 11.5 kW (about 5 to 15 hp).
The vehicle builders named are ZHEJIANG QIYE SCOOTER CO., LTD and Zhejiang Qiye Scooter 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.
