Motorcycle Tail Bag | Modular 10L 20L 30L Waterproof Rear Seat Luggage

Q1: What factory certifications and quality assurance do you provide?

FMOSBAG is a professional motorcycle bag manufacturer based in Fujian, China, holding ISO9001 quality system certification and BSCI factory audit. Every order undergoes 100% pre-shipment inspection, including shell water-repellency tests, liner taped-seam waterproof tests, buckle tensile tests and strap load tests, and all materials comply with ROHS and REACH standards. Full qualification documents and test reports are available for wholesale clients.

Q2: What is the OEM customization process and production lead time?

We support full OEM/ODM customization on fabric, color, size, structure, accessories, hang tags and retail packaging, with silk-screen printing, embroidery, woven labels and rubber patches. Design drafts are provided within 2 working days, pre-production samples take 5-7 working days, and bulk production finishes within 25-35 days after sample approval. A dedicated account manager tracks the entire order and updates progress regularly.

Q3: What is your MOQ, and do you accept small trial orders for new buyers?

The MOQ for fully customized orders is 300 pieces, which suits brand owners and motorcycle gear retailers. Stock samples are available from 1 piece for quality evaluation, and small trial orders are negotiable, helping new cross-border sellers test market demand with low upfront cost and inventory risk.

Q4: How do the 10L, 20L and 30L modular bags combine into a larger luggage set?

Each modular rear bag has quick-release buckles on both sides, so two pieces clip together in seconds as balanced side panniers, while a three-bag layout (20L+30L+20L) reaches about 70L for long-distance touring. Every piece also works alone on the rear seat or rack, so riders can start with one bag and add more sizes later without changing their mounting system.

Q5: Is the motorcycle tail bag waterproof enough for riding in heavy and sustained rain?

Yes, when the removable liner and roll top are correctly closed. This two-layer design pairs a water-repellent polyester shell that blocks splashes and light rain with a removable fully waterproof taped-seam liner that provides the main protection in sustained downpours. The zippered shell alone is not submersible, so riders should always fit and zip the liner in heavy rain; the liner also doubles as a standalone dry bag for camping and boating.

Q6: How does the bag mount to the bike, and can it be carried off the motorcycle?

Each bag ships with four buckle straps and four fixing straps for tool-free installation on the rear seat, luggage rack, side frames or crash bars of most street bikes, cruisers, adventure bikes, sport bikes and scooters, and it stays stable at highway speed when straps are kept clear of the wheel, chain and exhaust. Off the bike, the top handle and removable shoulder straps convert it into a single-shoulder or crossbody bag, and it folds flat when empty.
