This is a lightweight and durable under-saddle bag, easy to install, providing storage for essentials, and suitable for mountain, road, city bikes, and e-bikes.
Includes a transparent PVC mudguard to shield you from splashes and mud. The mudguard is quick to fit and remove, making cleaning simple and hassle-free.
Provides enough room for everyday essentials such as tools, keys, and mini pumps. Please note: this saddle bag is not large enough to hold a mobile phone.
A rear light can be attached to the back of the bag to alert vehicles behind you during night rides. (Tail light not included.)
Features two attachment points—one on the seat post with a quick-release bracket and another on the seat tube with Velcro. The bag remains secure and stable even on rough terrain. Suitable for seat post diameters of 43–64 mm.
Shaped to avoid obstructing leg movement, compact enough to carry anywhere. Uses a pressure-sealed zipper for airtightness; when reaching corners, use both hands for smooth operation.
