Our take on the Spark D2 16x4.0" Moped-Style E-Bike

The Spark D2 is a moped-style electric bike with a 750W motor (1800W peak), a 48V 15.6Ah battery rated for up to 65 miles, and 16x4.0" fat tires on full suspension. It tops 30 mph and carries up to 360 lbs, and the rear rack version adds cargo capacity. The best new price is $679 at Qlife Ebike as of November 4, 2026, and only one store lists it new, so there is no meaningful price spread to compare against.
