Aluminum Alloy Frame
Frame Material: 6061 Aluminum Alloy for Heavy-Duty Cargo Performance
Crafted from 6061 aluminum alloy, this cargo e-bike frame prioritizes load-bearing stability and long-term durability. The alloy's high tensile strength ensures rigidity under heavy payloads, resisting flex during urban commutes or industrial hauls, while its corrosion-resistant properties withstand rain, road salts, and daily wear. Designed to integrate seamlessly with hub motors, the frame optimizes weight distribution for balanced handling, whether navigating tight city streets or climbing gradients with cargo. The material's vibration-damping characteristics enhance rider comfort, even when carrying maximum capacity.Welding Process: Downhand Position Welding for Structural Integrity
The downhand welding technique ensures consistent, high-quality joints across the aluminum alloy frame's critical stress points. By maintaining optimal heat control and weld pool stability, this method produces smooth, uniform seams that excel in fatigue resistance-key for cargo bikes enduring repetitive load cycles. The process reinforces motor mounts and cargo rack interfaces, preventing cracks under hub motor torque or sudden stops. Precision in downhand welding translates to a robust foundation, ready to tackle years of heavy-duty service without compromise.
6061 Aluminum Alloy Frame
Constructed from aerospace-grade 6061 aluminum alloy, this cargo aluminum alloy frame combines lightweight agility with industrial-strength durability. The alloy's superior fatigue resistance ensures reliable performance under heavy loads, while its natural corrosion resistance safeguards against weather exposure during urban deliveries or long-haul cargo trips.20" Wheel Optimization
The compact 20" wheels enhance maneuverability in tight urban environments while maintaining stability under heavy cargo loads. Their smaller diameter allows quicker acceleration from stops-ideal for stop-and-go delivery routes-and lowers the bike's center of gravity for safer handling when transporting bulky items.
Custom Frame Sizes (16"/17")
Available in 16" and 17" sizes, this frame accommodates riders of varying heights without compromising cargo capacity. The size-specific geometry ensures ergonomic pedaling posture for efficient power transfer, critical for hauling heavy loads, while maintaining ample standover clearance for easy mounting/dismounting during frequent deliveries.Downhand Position Welding
Precision downhand welding creates uniform, deep-penetration joints at horizontal angles, maximizing structural integrity in high-stress areas like the bottom bracket and cargo rack mounts. This method ensures consistent weld quality for enhanced load-bearing capacity, crucial for cargo e-bikes subjected to constant vibrations and weight shifts.
Cargo E-Bike Design
Engineered for utility, the aluminum cargo frame features reinforced mounting points for racks, panniers, and child seats. Its rigid rear triangle prioritizes payload stability over rough surfaces, while the lightweight aluminum construction offsets battery and cargo weight to extend riding range. The hardtail design simplifies maintenance, ensuring reliability for daily commercial or family use.
