Cargo Bike Frame

Frame Material: 6061 Aluminum Alloy for Cargo Reliability

Engineered with 6061 aluminum alloy, this cargo bike frame delivers a robust yet lightweight platform for heavy-duty urban logistics. The alloy's high strength-to-weight ratio ensures stability under max payloads, resisting torsional flex during sharp turns or sudden stops, while its corrosion resistance combats rain, road salts, and frequent washdowns. Optimized for Bafang M400 hub motors, the frame's geometry balances motor torque efficiency with cargo rack integration, maintaining nimble handling even when fully loaded.

Welding Process: Downhand Position Welding for Load-Ready Joints

The downhand welding technique ensures uniform, high-strength seams across the frame's stress-prone zones. By maintaining precise heat control during vertical welding passes, this method minimizes porosity and weak spots-critical for cargo bikes enduring constant vibration and motor-driven torque. Reinforced welds at the rear dropout and motor mount areas prevent fatigue cracks, while smooth bead profiles enhance long-term durability under daily industrial use.

6061 Aluminum Alloy Cargo Frame

Built with high-strength 6061 aluminum alloy, this cargo bike frame offers an ideal blend of lightweight design and load-bearing durability. The alloy's exceptional rigidity ensures stability when carrying heavy payloads, while its corrosion-resistant properties withstand daily exposure to urban elements, making it perfect for commercial or family cargo use.

20" Cargo-Specific Wheels

The 20" wheels optimize maneuverability in dense urban settings, allowing tight turns and easy navigation through traffic. Their compact size lowers the bike's center of gravity, enhancing stability when loaded with cargo, while robust rims and reinforced spokes ensure reliable performance under constant heavy-duty use.

Frame Size(16"/17")

Available in 16" and 17" frame sizes, this cargo bike caters to riders of varying heights while maintaining optimal cargo space. The size-specific geometry ensures a comfortable, upright riding posture for better control during loaded rides, paired with sufficient standover clearance for safe mounting and dismounting during frequent stops.

Downhand Position Welding

Utilizing downhand welding techniques, critical joints like the cargo rack mounts and head tube are reinforced with deep, uniform welds. This method enhances structural integrity in high-stress areas, ensuring the frame withstands repetitive vibrations and heavy loads without compromising long-term durability.

Purpose-Built Cargo E-Bike Design

Engineered for utility, the frame features reinforced attachment points for racks, panniers, and child seats, supporting versatile cargo configurations. Its rigid rear triangle prioritizes payload stability, while the aluminum construction offsets battery weight to maximize range. The hardtail design minimizes maintenance, ensuring reliability for daily deliveries or family errands.
