It also has an additional advantage as it is highly water-repellent with plenty of space to take extra items with you. This Tarpaulin bicycle bag is made of 100% polyester cloth-like material coated on both sides, ensuring its long-term waterproof use. This pannier bag can be easily mounted on e-bikes without any tools. The two sturdy bottom plates ensure that the bike bag always stays stable. Additionally, the extra-large reflective badges on the front and rear panels help you stand out in the traffic, especially in the dark.
