- 15mm Puncture-Resistant Layer: With a scientifically designed 15mm thickness, it provides super strong protection for the tire. Acting as an "armor" for your outer tire, it reduces puncture risk by over 90%. Effectively prevents sharp objects such as gravel and nails from piercing the tire and interrupting your ride, eliminating the trouble of frequent flats.
- Compatible Models: This 20x4 Armour Tire Insert is compatible with the outer tires of 20x4-sized bicycles and e-bikes.
- Premium Material: This full-circumference protective armour tire is made of lightweight engineered composite materials, which are non-toxic, odorless and pollution-free. It not only resists penetration by sharp objects, but also absorbs road vibrations, bringing riders better comfort and stability.
- Easy Installation: This 20x4-inch Armour Tire Insert is lightweight, flexible and highly elastic. It can be easily inserted into the outer tire and fits perfectly against the inner wall of the outer tire. Place it between the outer tire and the inner tube. It will automatically revert to a circular shape after unpacking.
