Rhinowalk Motorcycle Tail Bag — Expandable 40–60L Waterproof Trunk Bag with Helmet Rain Cover

The Rhinowalk Motorcycle Tail Bag is a waterproof, expandable 40–60L trunk and sissy-bar luggage solution that secures to most touring and street bikes and includes straps, shoulder carry options, and a helmet rain cover.

Whether you commute across town or plan a multi-day ride, this tail bag from Rhinowalk is built to hold gear reliably while resisting wear and weather. Its reinforced frame and anti-slip base keep the load stable on bumpy roads, and the expandable design gives you flexible capacity when you need extra room without permanently adding bulk.

How much gear does this tail bag actually hold for a weekend trip?

Use it compact for everyday carry or expand for longer rides: the bag offers about 40 liters in its standard configuration and extends to roughly 60 liters when unzipped. When not in use it folds down to a slim profile for easy storage.

• Folded storage: 16.9 × 13 × 3.1 inches

Will it stay put on rough roads and in wet weather?

Rhinowalk designed the bag with a reinforced steel-wire frame, PE board support and an anti-slip, wear-resistant bottom to reduce shifting under load. The included straps and a buckle closure system help maintain tension so the bag stays secured over bumps, while the rain cover keeps contents dry in heavy showers.

• Four attachment straps for secure mounting to racks or sissy bars
• Buckle-with-lock function prevents strap loosening from vibration
• Waterproof helmet rain cover with drawstring to resist wind lift
• Durable, tear-resistant outer fabric with reinforced framing

How easy is it to carry and access my gear off the bike?

The bag includes a detachable shoulder strap so it doubles as a duffel for off-bike travel, and the top elastic band plus double-sided zip pockets help you organize and grab items quickly. External extension straps let you attach bulky items like a jacket or sleeping pad to the bag exterior.

• Removable shoulder strap for convenient carry off the motorcycle
• Top elastic band for hanging small items or a jacket
• Double-sided zip pockets for quick access to tools or documents
• Two external extension straps to secure oversized gear

Which motorcycles will this tail bag work with?

This tail bag is sized and equipped to fit a wide range of large and medium ADV touring bikes, short to medium-distance street motorcycles, and urban retro cruisers. Its adjustable straps and stable base make it adaptable to trunks, rear racks, and sissy bars on many models.

• Compatible with large and medium ADV touring bikes
