Frequently Asked Questions

Q: Will this bicycle frame tube bag fit my e-bike or mountain bike frame?

A: Yes. The Nixie frame tube bag uses adjustable hook-and-loop straps that wrap securely around most standard top-tube and under-tube frame sizes, making it compatible with e-bikes, mountain bikes, road bikes, and commuter bikes. We recommend measuring your frame tube diameter against the strap length before purchasing to ensure the best fit.

Q: Is the bag truly waterproof, or just water-resistant?

A: The bag is constructed from water-resistant PU material that effectively reduces rain penetration and protects against light rain and splashes. It is designed for everyday wet-weather riding rather than full submersion, so for heavy downpours we suggest placing valuables in a small zip-lock bag inside for added protection.

Q: How do I attach and remove the frame tube bag?

A: Attachment is completely tool-free. Simply wrap the hook-and-loop straps around your top tube or under tube and press them firmly to secure. To remove, peel back the straps — the whole process takes just a few seconds, making it easy to transfer the bag between bikes or take it with you when you park.

Q: What can I store in the frame tube bag?

A: The large-capacity interior comfortably fits a water bottle, smartphone, compact multi-tool, portable power bank, energy gels or snacks, keys, and other small cycling accessories. The rigid shell design keeps contents protected from bumps and compression during your ride.
