Backpack Bike Panniers-Product Description
Backpack Bike Panniers from FMOSBAG are waterproof rear rack storage bags made in Fujian, China, built for daily commuting and long-distance bicycle touring. Each bag is crafted from high-density 600D PVC coated polyester with an IPX6 roll-top closure that blocks heavy rain and road mud splashes, and the standard 27L body flexibly adjusts between 20L and 36L with a built-in zipper pocket for small accessories.
Tear-Resistant Build, Universal Rack Fit & Reflective Safety
Furthermore, these Backpack Bike Panniers use an upgraded 600D PVC polyester that offers better tear and scratch resistance than standard 500D PVC, with an abrasion-resistant reinforced bottom for daily use; an adjustable quick-release buckle base on the back fits most standard rear racks, and high-brightness reflective marks on both sides improve visibility on early morning and night rides.

Off-Bike Carry & Bulk OEM Customization
In addition, these E Bike Panniers include a removable curved shoulder strap and a soft top carry handle, so each bag switches between a rack bag, a shoulder bag and a handbag off the bike; full OEM & ODM customization on logo, packaging and structure is available for global bicycle gear wholesalers.
