What the Hammer Brand filings say about the engines
Every Hammer Brand filing on record is carburetted — 48 certificate rows, 2009 to 2026, and not one fuel-injected engine among them.
The engine codes on Hammer Brand's test vehicles —4 distinct across the filings — are led by BN157QMJ, BN139QMB, 1P52FMI and FT1390MB. The code is stamped on the crankcase and is a better search term than the badge.
31 of the 48 filings are 50-state (California-legal); the other 17 were 49-state only.
Rated power across the range runs from 2 kW to 6.4 kW (about 3 to 9 hp).
The vehicle builders named are Taizhou Zhongneng Motorcycle Co.,Ltd. and Chongqing Andes 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.
