Rhinowalk Motorcycle Tail Bag - Expandable 23L to 35L Waterproof

In this review the Rhinowalk Motorcycle Tail Bag is evaluated for riders who need a sturdy, weatherproof luggage option that fits on a trunk, rack or sissy bar. The single biggest reason to buy is the bag's expandable capacity: it serves as a compact 23L tail bag for everyday rides yet expands to 35L to hold a full-face helmet when needed, all while using a thick EVA shell and a lockable zipper to protect gear. Riders who prioritize weather resistance and stability will find the bag particularly useful.

Key Features

• Expandable Capacity: The main compartment expands from about 23L to 35L so riders can carry everyday items or pack a full-face helmet without hassle.
• Fully Waterproof Inner Bag: Includes a separate inner bag made from enforced polyester with a PU6000MM rating and sealed seams to keep contents dry in heavy rain.
• Stiffened EVA Shell: Thickened and moldable EVA construction offers shock absorption and structure to protect fragile items on the road.
• Secure Attachment: Comes with multiple 2.5cm webbing straps and sissy bar compatibility to attach securely under a seat or to a rack for long-distance stability.
• Lockable Zipper: Lock-ready zipper gives an extra layer of security for overnight or commuter storage.

Who It's For

Riders who need flexible luggage for mixed use will benefit most: commuters who sometimes carry extra gear, weekend tourers who may need to stow a helmet, and anyone who rides in wet conditions and needs reliable waterproofing. The bag's structured shell and straps make it a practical choice for motorcycles with trunks, racks or sissy bars.

Those who should look elsewhere include riders seeking ultra-lightweight minimalist tail pouches or hard-shell top cases keyed to a specific rack system; this bag weighs just under 2 kg and is designed as a soft-expandable luggage option, not a rigid lockbox solution.

Pros & Cons

Pros

• Expandable design provides versatile capacity from about 23L up to 35L to fit a full-face helmet when expanded.
• Waterproof inner bag with PU6000MM fabric and welded seam tape keeps contents dry in bad weather.
• Thickened EVA body adds protection and structure, preventing collapse and absorbing shocks.
• Includes straps and a lockable zipper for secure mounting and luggage security on long rides.

Cons

• At about 1.92 kg the bag is heavier than minimalist tail pouches, which may matter to riders seeking the lightest load.
• Attachment depends on webbing straps and sissy bar fit; riders without compatible mounts may need adapters.
