Max. phone screen size
The maximum diagonal of a smartphone that can fit in a phone bag. Note that this figure is quite approximate: mobile phones with the same screen size may have different actual dimensions.
Capacity
The total volume of the bike bag determines the amount of content that can be placed inside. When choosing according to this parameter, it should be borne in mind that a large capacity affects the dimensions of the bike bag. For use in the city, compact bicycle bags of a small volume are more suitable. They can carry personal items, repair kits and spare clothes. If you take a larger bag, it may well replace a backpack on a trip, which will relieve your back.
Material
— Polyester. Polyester-based synthetic fiber has good strength, moisture resistance, low exposure to ultraviolet radiation and temperature extremes. Moreover, polyester bags are relatively inexpensive. Note that the specific degree of strength and durability depends on the grade of polyester: the more expensive the bag, the more reliable the material, as a rule.
— Nylon. A type of synthetic fiber similar in properties to polyester. The density and overall quality of nylon can vary, but in general this material is characterized by strength, reliability, it also retains moisture well and can be supplemented with water-repellent impregnations. Often the properties of nylon fiber are directly related to the price category of the bike bag.
Reflectors
Reflective elements on the side walls of the accessories increase the level of passive safety while driving at night and in low visibility conditions. This feature makes the cyclist more visible on the road, which has a positive effect on the safety of movement and reduces the risk of an accident.
