What are the exact dimensions of this bag, and will it fit on my bike's top tube?

According to the description, the bag measures approximately 19.5 x 13 x 6.3 cm. The product listing also states 21 x 15 x 8 cm. It is designed as a top tube bag and should fit most standard bike frames, but measure your available space to be sure.

Is this bag fully waterproof, and how should I care for it?

The bag is made of waterproof material but does not include a rain cover, so it may not be fully sealed against heavy rain. Clean it with a damp cloth and avoid submerging.

What comes in the package with the bag?

The package includes only the bicycle front bag itself. It features a zippered main compartment and an impact-resistant pad to protect items like phones or cameras.

Who is this bag not suitable for?

This bag is not suitable for overnight bikepacking requiring large capacity, for use in heavy rain without additional waterproofing (no rain cover), or for riders who prefer quick-release magnetic bags.

What is the typical shipping time and process for this product?

The product ships from China. Delivery typically takes 7–30 days depending on the shipping tier. Checkout requires human approval, so there may be a slight delay before processing.
