Description LOBOO – IPX6 Waterproof Motorcycle Rear Bag, 40 to 90 L

The LOBOO BWB Series Waterproof Rear Case combines large capacity with water resistance: a technical PVC body with seamless high-frequency welds, a patented magnetic roll-top closure, and rated IPX6 protection. Four capacities: 40, 50, 66, and 90 liters.

The front air-release valve expels excess air after closing: the load compresses, and the case remains stable on the seat even when it is not full. This is why a large, partially filled case does not become bulky.

Key features

  • Patented magnetic roll-top: closes in one motion, even while wearing gloves
  • IPX6: withstands high-pressure water jets, heavy rain, and dust
  • Seamless high-frequency welding, with no points where water can enter
  • Air-release valve to compress the load and eliminate the balloon effect
  • Dry/wet separator compartment, plus two side pockets
  • Reflective inserts on all sides for nighttime visibility
  • Included: detachable shoulder strap and two LOBOO quick-release straps

Three ways to secure it

The LOBOO manual documents three procedures: two using the included quick-release straps, attached to the fixed mounting points on the sides of the tail section, and a third that routes the lid buckles through non-elastic third-party straps if you prefer your own fastening system.

Good to know: IPX6 means protection against water jets, not immersion. The roll-top must be rolled down for several complete turns and closed with both buckles before riding.

Why choose it
  • Bleeder Valve:expels excess air and compresses the load, so even a partially filled 66 L bag remains stable.
  • Magnetic Roll-Top:one-motion closure, no velcro or buckles to align.
  • Wet/Dry Separation:internal compartment for damp or dirty clothes.
  • Dual Side Pockets:quick access without opening the main compartment.
  • Technical PVC:wear and tear resistant, easy to clean. Multi-directional reflectors for visibility.
Who is it recommended for

How to choose the volume:

  • 40 L and 50 L: The everyday companion. An overnight trip, a short weekend, day trips.
  • 66 L: The touring size. It's the right balance for a five to seven-day trip.
  • 90 L: For those who don't know what "traveling light" means, or are going on a multi-week expedition. It has the same base as the 66 L: it only grows in height.

Thanks to the bleed valve, the larger volume, when not fully filled, doesn't become bulky: if you're undecided between two sizes, the larger one gives you more leeway without penalizing you on short trips.

Four colors: Black and military green if you prefer to go unnoticed, yellow and fluorescent green if you want to be seen. On the latter two, the reflective inserts work together with the background color, and at night the difference from behind is noticeable.

A detachable shoulder strap and two quick-release straps are included with every version: the bag can also be carried by hand once you get off the motorcycle.

Documents and manufacturer

Usage and notes

  • Manufacturer-declared protection rating: IPX6. Covers heavy rain, high-pressure water jets, and dust, but not immersion.
  • Roll the roll-top for several full turns and fasten both buckles: the seal depends on the closure, not just the fabric.
  • After closing, use the front valve to expel air: this improves the seal and stability on the motorcycle.
  • Cleaning (manufacturer's instructions):Damp soft cloth and neutral soap after each use. Bleach, fabric softener, and acidic or alkaline detergents are prohibited; machine washing, ironing, dry cleaning, and artificial drying are prohibited. Allow to dry naturally and avoid prolonged exposure to sunlight.
  • Storage:In a dry and cool environment to prevent mold, periodically cleaning dust and dirt from the surface.
  • Before riding, check the handle, shoulder strap, and quick-release straps. Do not use insect repellents on the fabric and avoid contact with sharp objects: they would compromise waterproofing.
  • The load must not cover the license plate and rear lights or protrude beyond the limits set by the Highway Code.
  • The manufacturer's warranty is 12 months and is a conventional supplement: it does not replace the 24-month legal warranty of conformity provided for the consumer.

What does it look like in detail?

The roll-top that aligns itself automatically

The roll-top that aligns itself automatically

Inside the opening, there’s a magnetic strip: bring the two edges together and they align on their own, so you don’t have to hold them in place with your fingers. Then roll it up and fasten the side buckles.

It seems like a small detail until you have to do it with gloves on, in the rain, at a service station. That’s exactly when a hook-and-loop closure costs you two minutes and gets whatever you’re loading wet.

The valve that keeps the half-empty 66 L stationary

The valve that keeps the half-empty 66 L stationary

With the roll-top closed, air remains inside. When the bag is half full, this creates a bulky volume that the straps cannot secure: it starts out stable, and after a few bends you feel it shifting behind your back.

The release valve expels excess air once the bag is sealed. The load compacts, the profile becomes lower, and the center of gravity drops. That is why you can choose the 66 L without ending up with a balloon on the saddle on short trips.

Technical PVC: water slides off

Technical PVC: water slides off

The body is made of technical PVC: smooth, resistant to abrasion and tearing, with water sliding off instead of being absorbed. It does not become waterlogged or heavy, and it can be cleaned by wiping it with a damp cloth.

It is the same material that allows the roll-top to truly seal once rolled up: the seal depends on the combination of fabric and closure, not on the fabric alone. Always roll it for several complete turns before setting off.

The dry side on one side, the wet side on the other

The dry side on one side, the wet side on the other

Inside, there’s a dedicated divider compartment for damp or dirty clothing. It’s exactly what you need when you finish a rainy leg and have to stow your rain gear without wetting your clean clothes.

On the outside, two quick-access side pockets keep essentials within reach during a stop: spare gloves, documents, or a snack. You don’t have to open the roll-top every time.

It attaches and detaches in just a few seconds

The quick-release buckles are positioned at the front, back, and sides: the two included straps secure the case to the seat, tail section, or existing luggage rack, without needing to buy separate plates or adapters.

All you need is a suitable support surface: 53 × 27 cm for the 40 L, 58 × 29 cm for the 50 L, 64 × 31.5 cm for the 66 L, and 64 × 39 cm for the 90 L. Measure the tail section before choosing the capacity, especially if your motorcycle has a short tail.

They see you from behind, and you carry it by hand.

They see you from behind, and you carry it by hand.

Reflective inserts run along all four sides, not just the back: in the dark, the outline is visible even from a three-quarter angle, which is where overtaking vehicles approach. If you often drive at night, the yellow and military green add visibility even with the headlights off.

The package includes the detachable shoulder strap and quick-release strap. When you arrive, unclip them and the suitcase becomes a duffel bag you can carry to your room without transferring anything.

FAQs

For more information, please see our FAQ.

Which volume should you choose: 40, 50, 66, or 90 L?

The 40 L (53 × 27 × 28 cm, 1.96 kg) and 50 L (58 × 29 × 30 cm, 2.21 kg) are the everyday sizes: an overnight stay, a short weekend, or day trips. The 66 L (64 × 31.5 × 33.5 cm, 2.40 kg) is the touring size, designed for a five- to seven-day trip. The 90 L (64 × 39 × 36.5 cm, 2.57 kg) is for those heading away for weeks or carrying camping gear.

The practical criterion is not how much you carry, but how much tailbone you have: you need a support surface equal to the base of the suitcase. Note that the 90 L is the same length as the 66 L—64 cm: it grows in width and height, not length. If your tailbone can support the 66 L, it can support the 90 L too.

When in doubt between two nearby sizes, choose the larger one: the relief valve compresses the load, so when half empty it does not become unnecessary bulk.

How does wet and dry separation work?

There is a dedicated internal compartment for storing wet or dirty clothes separately from the rest of the load. The double side pockets, meanwhile, are for items you want to access without opening the suitcase.

Do you need a rack to mount it?

No. The package includes two quick-release straps that secure the bag directly to the existing seat, tail section, or luggage rack. However, a suitable support surface is required: 53 × 27 cm for the 40 L, 58 × 29 cm for the 50 L, 64 × 31.5 cm for the 66 L, and 64 × 39 cm for the 90 L.

What is the front valve used for?

After rolling and closing the roll-top, air remains inside. Open the valve and compress the bag to release the air, compact the load, and lower its profile. This is what makes the 66 L usable even when half full: without it, it remains a bulky volume that shifts on the saddle.

Is it waterproof underwater as well?

No, and it's right to be precise. LOBOO states IPX6: protection against high-pressure water jets, including heavy rain, splashes from trucks, and washing the motorcycle. Immersion, even brief, is the next level (IPX7), and this case does not cover it. If you need that level, look at the ALPS 46 L TPU bag. For normal use, IPX6 is more than sufficient, provided you roll the roll-top closed for several complete turns.

How much does each size weigh, and how bulky is it?

40 L: 53 × 27 × 28 cm and 1.96 kg. 50 L: 58 × 29 × 30 cm and 2.21 kg. 66 L: 64 × 31.5 × 33.5 cm and 2.40 kg. 90 L: 64 × 39 × 36.5 cm and 2.57 kg. These are the dimensions when full: with the compression valve, the actual bulk decreases considerably when the load is reduced. Note the difference between 66 and 90 L: the length remains 64 cm, while the height increases.

What colors is it available in?

Black, yellow, and military green on both volumes. The yellow and green, together with the multidirectional reflective inserts, help you stand out considerably from behind when riding at night. If the combination you're looking for is shown as out of stock in the selector, write to us: it often comes back in a few weeks.
