Frequently Asked Questions
Q: Is the waterproof bike trunk bag compatible with all bicycle racks?
A: Yes — the rear seat trunk bag is designed to fit most standard bicycle rear racks, including those on road bikes, mountain bikes, commuter bikes, and touring bikes. The secure strapping system ensures a stable fit across a wide range of rack widths and styles.
Q: Does the bag come with a rain cover?
A: The waterproof polyester and 900D film construction handles light rain and splashing effectively. However, for moderate to heavy rain, we recommend using an additional rain cover (not included) to provide maximum protection for your gear.

A: Style A includes the main trunk bag only (365 × 160 × 140 mm), which is ideal for everyday commuting. Style B adds two expandable side bags (270 × 260 × 60 mm each), providing significantly more storage capacity — perfect for longer tours or weekend bikepacking adventures.
