Design and Frame Construction
The SISIGAD cargo bike utilizes a step-through frame configured for family transport, complete with a rear passenger bench and protective wrap-around handrail. The manufacturer specifications present conflicting frame material claims, listing an aluminum frame in one bullet point and high-carbon steel in another. Buyers should confirm the actual metallurgical construction with the seller, as steel adds weight while aluminum reduces structural fatigue risks in humid environments. The chassis rides on 20-inch wheels wrapped in 3.0-inch tires, paired with a front suspension fork to absorb surface chatter. A total rated payload capacity of 450 pounds supports an adult rider alongside cargo or a small passenger. While the compact wheelbase aids urban storage, the low-step design ensures that mounting and dismounting remain manageable even when the rear platform is fully loaded with groceries or a seated child.
