BiKase Big Poppa Rack Bag - Strap Mount is a high-capacity rear rack bag designed for riders who want serious carrying space without committing to full-time panniers. The oversized main compartment handles bulky cargo, while the integrated drop-down panniers expand storage when the ride turns into an errand run or a commute with extra gear.
A seam-sealed waterproof liner in the main compartment helps keep contents protected from road spray and wet-weather riding. Practical external storage—like the top bungee net and an adaptable water bottle holder—keeps frequently used items within easy reach. The strap-mount design fits rear racks up to 7.5" wide, and a removable shoulder strap makes carry-off convenience straightforward.
Drop-down panniers - Extra cargo capacity on demand for commuting, shopping, or longer rides
