Rhinowalk Motorcycle Tail Bag, Expandable 40L–60L Travel Luggage — Black, Waterproof with Reinforced Frame & Helmet Rain Cover

Rhinowalk's 60L expandable motorcycle tail bag is a weatherproof, reinforced trunk bag that converts between a compact 40L pack and a roomy 60L luggage carrier with straps and a helmet rain cover.

Designed for touring riders who need flexible capacity and reliable attachment, this Rhinowalk tail bag blends tear-resistant fabric, a reinforced internal frame, and anti-slip base material to stay put on long rides. It ships with mounting straps, extension straps, a shoulder strap for off-bike use, and a drawstring rain cover so your gear stays dry and easy to access in varied conditions.

How much gear does the bag actually hold and how does expansion work?

The bag’s baseline volume is approximately 40L with compact external dimensions, and it expands to about 60L when the double-sided stretch zipper is opened. Expansion is accomplished by unzipping the outer gusset, which increases the height without affecting the stable base, letting you pack helmets, jackets, or multiple smaller items.

• Compact dimensions (closed): about 17.3 x 12.4 x 12.4 inches — ~40L usable volume.
• Expanded dimensions (open): about 24.4 x 12.4 x 12.4 inches — ~60L capacity.
• Folds flat to 16.9 x 13 x 3.1 inches for storage.
• Double-sided zipper allows quick conversion on the road.

What keeps the bag secure during bumpy rides and how are attachments handled?

Security comes from a combination of reinforced steel-wire framing, a PE board for stability, and strong webbing with buckles that lock when tightened. Four main straps anchor the bag to the rack or sissy bar, while two extension straps let you lash gear to the exterior; the design prevents tension loss from bumps.

• Four straps for permanent attachment to rack or sissy bar.
• Two extension straps for extra cargo or awkward shapes.
• Anti-slip, wear-resistant bottom keeps the bag from sliding.
• Buckle design locks when webbing is cinched to resist loosening.

How weather-resistant and durable is the Rhinowalk tail bag?

The outer fabric is tear-resistant mesh cloth reinforced at stress points, supported by a steel-wire frame and PE board to preserve shape and durability. A supplied drawstring rain cover protects the bag and its contents from heavy rain and wind; the bottom material is treated for abrasion resistance and improved grip.

• Tear-resistant outer fabric and reinforced internal frame for longevity.
• Durable, non-slip base material for wet or rough surfaces.
• Included helmet rain cover with drawstring to secure during storms.
• Double-sided zipper protected by flap to limit water ingress.

What convenience features help when packing, carrying, and accessing items?

The bag includes user-oriented touches such as an elastic top band for quick stow of a jacket or rope, external zip pockets for small items, and a detachable shoulder strap so the bag doubles as a duffel off the bike. Interior organization is straightforward, enabling separation of clothing, tools, and accessories without a lot of rearranging at each stop.

• Elastic top band for helmets, jackets, or items you need fast access to.
• Double-sided zippered pockets for phone, keys, and wallet organization.
• Removable shoulder strap converts the tail bag into a travel duffel.
• Buckles and straps arranged to minimize fumbling while mounting on the bike.

Who is this for: The Rhinowalk expandable tail bag suits riders of large and medium ADV touring bikes, city and short-distance street motorcycles, and retro cruisers who want a reliable, weather-ready luggage option. It’s ideal for weekend trippers who need flexible packing volume, commuters who want a secure daily carrier, and anyone who prefers a bag that converts easily between on-bike and off-bike use.
