1.Tail box material:
Plastic trunk: Common materials include PP (polypropylene) and ABS (acrylonitrile butadiene styrene). The tail box made of PP material has high strength and impact resistance, is lightweight and cost-effective, and is suitable for daily use. ABS material performs better in terms of toughness and wear resistance, with a higher appearance glossiness, but it is relatively expensive. The advantages of plastic trunk are impact resistance, resistance to deformation, versatile appearance, streamlined design that can reduce wind resistance, but the surface is prone to aging.
Aluminum alloy trunk: This material of trunk is sturdy and durable, with strong impact resistance, good waterproof performance, and a high-end appearance. Aluminum alloy trunk is suitable for long-distance cycling or situations where heavy items need to be carried, but the price is usually higher and the weight is heavier [^ 129 ^] [^ 135 ^].
2.Tail package material:
Tail bags are generally made of materials such as nylon cloth, EVA foam plastic, PU leather, etc. Nylon fabric is the most common material, which is cheap but has poor waterproofing. EVA foam plastic is used for hard shell tail bags, providing better visual effects and durability. PU leather has good waterproof properties and is suitable for occasions that require durability and waterproofing.
Some high-end tail bags may use materials such as wax cloth, which have better waterproof and wear-resistant properties.
In summary, the trunk is usually made of plastic or aluminum alloy material, emphasizing durability and sturdiness, while the tail bag is often made of lightweight fabric, emphasizing flexibility and portability. The choice can be made based on individual needs and usage scenarios.
