Weight standard
Priority should be given to vehicle models with a weight of ≤ 8kg (recommended range: 6-8kg), and aviation aluminum alloy or carbon fiber is preferred for the frame material, balancing lightweight and load-bearing capacity.
Ultra lightweight models: DKF-A8 (3.9kg), DKF-T18 (4.2kg).
Folding design
It needs to be folded within 3 seconds with one hand, and the folded volume should be ≤ 60 × 50 × 30cm.

Suspension system
Lightweight vehicles must be equipped with at least four-wheel spring suspension and EVA foam tires.
It is recommended to choose a model with a universal wheel diameter of ≥ 12cm for complex road surfaces.
Sunshade and ventilation
The full canopy cover should be covered with UPF50+sun protection certification, and the ventilation system should prioritize a combination of top sunroof and back breathable mesh.
