Motorcycle Luggage Bags | Expandable Waterproof Rear Seat Travel Backpack

Q1: What factory qualifications and quality support do you provide for wholesale orders?

FMOSBAG is a professional motorcycle bag manufacturer based in Fujian, China, operating under ISO9001 quality management and BSCI factory audit, with ROHS and REACH compliant materials. Every order receives 100% pre-shipment inspection, including fabric water-repellency tests, zipper durability tests, buckle tensile tests, strap load tests and rain cover fitting checks. Full qualification documents and test reports are available for wholesale and brand clients.

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

After you confirm logo, color, size, structure and packaging requirements, we provide design drafts within 2 working days. Pre-production samples take about 7 working days, and bulk production is completed within 25-40 working days after deposit and PP sample approval. A dedicated account manager tracks the whole process, and we support silk-screen printing, embroidery, woven labels, rubber patches and custom retail packaging.

Q3: What is your MOQ, and do you support small trial orders?

Stock items support a minimum order of 20 pieces, which helps new cross-border sellers test the market with low upfront risk. Fully customized orders with exclusive logo and packaging require an MOQ of 300 pieces. We also accept mixed trial orders across our motorcycle bag range, with flexible scaling once your sales data is confirmed.

Q4: How much can these expandable motorcycle luggage bags carry?

The base size of 36×34×27cm offers about 33L, which covers daily commuting and weekend rides. Opening both expansion zippers adds 8cm on each side and about 14.6L in total, expanding the bag to roughly 48L — large enough for one full-face helmet plus clothing, rain gear and touring essentials. The side-opening main compartment also fits a laptop, and the external attachment points carry a tent, sleeping mat and trekking poles for camping trips.

Q5: Are these bags fully waterproof in heavy rain?

The body is made of 1200D Oxford fabric with a water-repellent coating that resists light rain, road splashes and dust. For heavy and continuous rain, every bag includes an external waterproof rain cover that slips on quickly for full protection. As a zippered soft bag, it is not designed for submersion; for OEM orders we can also upgrade waterproof zippers and taped seams on request.

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

Four mounting straps (two short 49cm and two long 100cm) fasten the bag to the rear seat or luggage rack with multi-point fixation, keeping it stable at highway speeds and on bumpy roads. The removable 75-130cm shoulder straps then convert it into a backpack for hotel stops, and the large non-slip rubber base protects the seat paint. When the trip is over, the empty bag folds flat in three steps for compact storage.
