The engine, as described on the certificate

The test vehicle Segway Powersports submitted for this family (model SGW1000F-A5) carried engine code 293MY-2. In the Chinese engine-model convention that reads as 2 cylinders with a nominal 93 mm bore, MY series. Against the certified 999.9cc that implies a stroke of roughly 74 mm — a sanity check for a piston or cylinder listing, not a published figure.

The certificate describes a four-stroke, twin-cylinder engine with 4 valves per cylinder fed by sequential multi-port fuel injection, with an oxygen sensor for closed-loop fuelling, run by an engine control module (ECM). There is a catalytic converter in the exhaust, recorded as "Three Way Catalyst (TWC), single-bed, closed-loop warm up".

Rated power on the record is 71 kW (about 95 hp) at 8,000 rpm, driving through a CVT (belt and variator).
