Waterproof Motorcycle Rear Seat Bag 80L

Waterproof Motorcycle Rear Seat Bag shields your gear. The 80L capacity stretches for cargo. Heavy duty PVC blocks rain. Secure rider storage arrives today.

Key Features

You need reliable storage that survives the road. This bag uses fused PVC outer layers and woven polyester lining to stop moisture. You get an expandable chamber that slips from compact riding to loaded touring. Sturdy webbing loops grip standard tail racks. The clean silhouette blends behind any saddle.

Product Description

Riders demand gear that handles sudden downpours and rough pavement. This model answers that call with thick protective panels and reinforced stitching. You simply fill the compartments, tighten the straps, and hit the highway. The design avoids bulk while keeping your equipment separated and dry.

Product Overview

This luggage piece targets unisex adults who want durable soft cases instead of rigid plastic boxes. Rhinowalk engineered multiple size tiers to match different bike frames. You attach it directly to your rear cushion or under-seat rack. The classic aesthetic complements touring, cruiser, and adventure setups equally.

Key Benefits

  • All-Weather Protection Sealed seams and hydrophobic fabric keep contents dry during heavy storms.
  • Instant Capacity Change Slide out the expansion zipper to gain extra inches when you park.
  • Stable Ride Comfort Weight sits low behind the seat to maintain handling balance.
  • Quick Deployment Standard buckles require zero tools for fast mounting.

Features

  • Material Tech Water resistant PVC coating covers a strong polyester base.
  • Model Codes Select MT4026, MTR4045, MT4060, or MTR4080 for your preferred volume.
  • Load Grading Reinforced stress points distribute pressure evenly across your straps.
  • Clean Finish Tuck-out zippers and flat seams prevent snagging on gloves.

Specifications

  • M Model (MT4026) Weighs 2000 grams. Measures 32×30×22 cm normally. Expands to 40×30×22 cm.
  • L Model (MTR4045) Weighs 2530 grams. Measures 40×30×27 cm normally. Expands to 55×31×27 cm.
  • XL Model (MT4060) Weighs 3200 grams. Measures 44×31.5×31.5 cm normally. Expands to 62×31.5×31.5 cm.
  • XXL Model (MTR4080) Weighs 3480 grams. Measures 50×33×36 cm normally. Expands to 68×33×36 cm.

What’s Included

Each unit ships with the main storage pouch, four reinforced securing straps, and a hardware buckle set. Everything lands in a compact mailer box so you can inspect it immediately after cutting the tape.

How to Use

Place the bag over your passenger seat section. Thread the lower straps under the frame rails. Pull high until tension removes slack. Click the side locks into place. Give the pouch a firm tug to confirm stability before rolling.

Customer Benefits

You keep expensive electronics insulated from heat and dripping condensation. The lighter build saves fuel compared to metal panniers. Fast packing cycles mean you leave faster. Reduced rattling creates a quieter cabin experience.

Ideal Uses

Daily delivery routes requiring quick locker swaps. Weekend mountain trips needing spare tool kits. Long distance highway tours holding change of clothes and photography backups.

Who It’s For

Commuters, cargo cyclists who occasionally swap to motorbikes, vintage restoration owners, and budget conscious travelers who prefer flexible packing solutions.

Frequently Asked Questions

Does this bag survive heavy downpours?
Absolutely. The PVC shell repels water reliably during normal riding conditions.

Will it rattle over potholes?
No. Tightened mounting straps anchor solidly to your seat frame to eliminate movement.

How many model sizes exist?
We offer M, L, XL, and XXL tiers for varied cargo volumes.

Can I detach the shoulder pads?
Adjustment clips loosen quickly for manual carried transport.

Is it compatible with heated seats?
Remove the bag thoroughly whenever activating seat heaters.

Very good finish and quality. yet to be tested its durability in the elements . i got the biggest size which is xxl and that can just fit inside my 3p tent

Damaris Terry

The bag is as described, it looks practical and has quite a bit of storage space, and the expandability is a plus. It comes with tie-down straps and a cover for rainy days. I will test it very soon for a one-month road trip across the United States, but I am quite confident, and we can even lock the closures with a padlock.

I'm so, so, so happy with this purchase. After years of using aliexpress, this is now my favorite purchase so far. Delivery was fast, the returns process (the first bag was too small, i went to order a larger one) was very easy, and the product itself is fantastic. Every single aspect of the bag was well thought out: every buckle has a latch to allow tightening or releasing, every strap has an elastic band to keep it tight, every storage zipper has a locking point for a padlock, and the inside has two solid panels to keep either the sides rigid or the bottom rigid; Depends on your choice. The quality is outstanding too, i'm genuinely so surprised that i'd be this excited over a bag from aliexpress.

Received the item very fast. As expected it is very good quality and well built. Due to this i'm getting the side bags also. This bag is a good size and fits the bike well. Due to the quality, it is quite heavy.

There are several reviews on this bag. I purchased 40/60 ltr for my v7 moto guzzi. It fits on the back seat and gives me plenty space as the rider. Bag is 1st class. So well thought out. Zippers excellent rain cover perfect. Ample space. Side access a game changer. If i paid twice the money i paid i would still say it’s a bargain. I’ve done motorcycle touring for 30 plus years and plenty different luggage systems. This bag super impressive. Could not be happier. Great seller fast postage absolutely awesome experience. I’m so happy 👌 👍
