|---|---|---|
| Motor Power | 750W–1300W | Strong acceleration and hill climbing |
| Torque | 60–85 Nm | Maintains power under heavy loads |
| Top Speed | Up to 28 mph | Quick urban travel with cargo |
How Does the Frame and Wheel Design Impact Strength and Stability?
The frame is typically built from aluminum alloy or chromoly steel, offering high strength-to-weight ratios and durability for heavy payloads. The 20-inch wheels are fitted with wide, fat tires — usually 3.5 inches or more — that absorb shocks and provide increased traction and stability. This combination promotes balanced handling despite the extra weight of the load.
What Are the Typical Payload Capacities for These Ebikes?
Payload capacity for 20” rear-drive cargo ebikes commonly ranges from 350 to 450 pounds, including rider and cargo. Spacious rear racks and cargo boxes are integrated to distribute weight evenly and support heavy items or even passengers, such as children, safely over urban terrain.
