a specialized cargo electric bicycle engineered with a reinforced 6061 aluminum alloy step-through frame for heavy load transport. It is powered by a 750W mid-drive motor that produces a peak output of 1140W and 100Nm of torque, utilizing a sophisticated torque sensor for responsive power delivery. This dual-battery configuration includes two 48V 19.2Ah lithium-ion batteries, providing a total capacity of 38.4Ah for extended range. For cargo stability, the bike is equipped with 20x3.0-inch puncture-resistant tires and an integrated extra-long rear rack. Braking is managed by 180mm hydraulic disc brakes, while the front hydraulic suspension fork provides shock absorption. Functional components include integrated front and rear turn signals, a high-luminance LED headlight, and a heavy-duty dual-leg kickstand for stable loading.
