Description LOBOO 20 L – IPX6 Waterproof Motorcycle Tail Bag with Magnetic Roll-Top

The 20-liter LOBOO rear bag (code BWB20PBK) solves the most annoying problem with dry bags: opening and closing them with gloves on. The roll-top has a magnetic strip embedded in the opening, covered by utility model patent ZL 2019 2 1740293.1: the two flaps align themselves, then it rolls up three times and closes with the two buckles.

It's the right size for a daily commute and short weekend trips, not for multi-day travel. Measuring 420 × 240 × 220 mm, it's light on the tail and attaches in seconds with the four quick-release straps included, to the seat, tail, or luggage rack: no need to buy anything else.

Main features

  • 20 liters, 420 × 240 × 220 mm
  • Patented magnetic roll-top closure: three rolls and two buckles
  • IPX6 waterproofing in eco-friendly PVC and polyester
  • Side air release valve to compact the load
  • Detachable shoulder strap and 4 quick-release straps included
  • Tear-resistant fabric, declared resistance up to 200 kg

Why magnetic and not velcro or zipper

Velcro damages technical clothing fabrics and loses grip with use; zippers jam and age poorly. The magnetic strip has no hooked surfaces, does not wear out, and maintains the same hold over time.

If you need more volume, the ALPS 46 L is IPX7 with an included hydration pack, and the Wanderer 50L is the choice for long trips.

Why choose it
  • Patented magnetic roll-top:the magnetic strip is embedded in the opening, and the flaps align themselves. Three rolls, two buckles, and you're done even with gloves on.
  • Doesn't damage technical clothing:no hook-and-loop fasteners, no zippers that jam or wear out.
  • Mounts without a rack:four quick-release straps included, for mounting on the seat, tail, or existing rack.
  • Air release valve:removes trapped air after closing and compacts the load, preventing it from shifting.
  • Shoulder strap included:detaches from the bike and can be carried over the shoulder or by hand, without transferring anything.
  • 20 L in 420 × 240 × 220 mm:compact size, also suitable for scooters and naked bikes, as well as adventure bikes.
Who is it recommended for

This is an everyday bag, not for long trips. It's useful if:

  • You use your motorcycle or scooter for commuting and want something that stays mounted
  • You find it annoying to open and close a dry bag while wearing gloves
  • You're going away for a one or two-night weekend and only need the essentials
  • You don't have a luggage rack and don't intend to buy one

For multi-day trips, go up a size: the ALPS 46Lis IPX7 and includes a hydration pack, while the Wanderer 50Lis the choice for long tours.

Documents and manufacturer

Use and notes

  • The IPX6 rating declared by the manufacturer covers high-pressure water jets, not immersion. Roll the roll-top down three full turns and fasten both buckles before setting off.
  • Position the straps away from the exhaust and secure any excess webbing so that it cannot get caught in the wheel or chain.
  • The declared fabric strength (200 kg) is not the permitted load: always respect the load capacity of the seat or rack indicated by the vehicle manufacturer.
  • The load must not cover the license plate and tail lights or extend beyond the limits set by the Highway Code.
  • The magnetic closure is covered by Chinese utility model patent no. ZL 2019 2 1740293.1, as declared by the manufacturer.

What sets it apart from any ordinary dry bag?

It closes by itself, even when wearing gloves.

It closes by itself, even when wearing gloves.

The problem with every waterproof bag is always the same: closing it properly while wearing gloves, perhaps in the rain and in a hurry. Here, the roll-top opening has a magnetic strip embedded in the fabric: bring the two flaps together and they align themselves, without having to hold them in place with your fingers.

From there, all it takes is three rolls and the two side buckles. LOBOO states that this solution is covered by utility model patent no. ZL 2019 2 1740293.1: it’s what truly sets this bag apart from generic waterproof bags at the same price.

Why not Velcro, and why not a zipper?

Why not Velcro, and why not a zipper?

Cheap waterproof bags close in two ways, and neither ages well. Velcro has a hooked surface that catches on technical clothing and damages it, and it loses its grip as it fills with dirt and fibers. Waterproof zippers are stiff, jam, and dry out over time.

The magnet has no surfaces that wear out: it doesn't catch on fabrics, doesn't collect dirt, and its holding power remains the same after months of daily use. You notice the difference most when you open and close the bag twice a day.

Eco-friendly PVC, IPX6 waterproof rating

Eco-friendly PVC, IPX6 waterproof rating

The body is made of eco-friendly PVC laminated with polyester: odorless, smooth, and causing water to run off instead of being absorbed. The stated rating is IPX6, meaning protection against high-pressure water jets: heavy rain, splashes from trucks, and washing the motorcycle.

IPX6 does not cover immersion, which is the next level. For use in the city and on weekends, you do not need more: what matters is rolling the roll-top closed for three full turns and fastening both buckles before setting off.

The valve that stops the load

The valve that stops the load

When you roll and close it, air remains inside. With the bag half empty, this creates a bloated volume that the straps cannot secure: it starts out firmly in place, but after twenty kilometers you can feel it shifting behind your back.

The side valve removes excess air once the bag is sealed. The load compacts, the profile becomes lower, and the straps regain their grip on a rigid volume. The fabric is ripstop, with a manufacturer-stated resistance of up to 200 kg.

Three ways to wear it

Three ways to wear it

On the motorcycle, it is a saddlebag secured with four quick-release straps. Undo those, and the included detachable shoulder strap turns it into a shoulder bag, or you can grab the top handle and carry it by hand.

That is why it works well for commuting: you arrive, unclip it, and walk into the office with the same bag. No need to transfer anything, and whatever you had inside stays dry even while crossing the parking lot in the rain.

20 liters: the everyday size

20 liters: the everyday size

420 × 240 × 220 mm is a compact size that fits behind the seat of both a scooter and a naked bike, without sticking out or forcing you to install a luggage rack. It fits a change of clothes, rain gear, a toiletry kit, and a charger: everything you need for the daily commute and a one- or two-night weekend trip.

It isn't a long-trip bag, and it's worth saying so: if you're leaving for several days or carrying camping gear, you'll need 40–50 liters, so it's worth looking at the ALPS 46 L or the Wanderer 50L.

FAQs

For more information, please see our FAQ.

Is the magnetic closure really patented?

Yes. LOBOO claims utility model patent No. ZL 2019 2 1740293.1 for the magnetic strip embedded in the roll-top opening. In practice, the two flaps align themselves when brought together: then you roll it three times and fasten the two buckles without having to remove your gloves.

Do you need a rack to mount it?

No. The package includes four LOBOO quick-release straps that attach it directly to the existing seat, tail section, or luggage rack. You don’t need elastic straps, cargo nets, or adapters purchased separately. If you already have a luggage rack, you can use it as a support surface, but it isn’t necessary.

How much space is needed behind the saddle?

The base measures 42 × 24 cm and is 22 cm high. You therefore need a support area of at least 42 × 24 cm and four points through which to pass the straps. Pay attention to the height: once loaded, make sure it does not cover the brake light, especially on scooters and naked bikes with short tails.

What is included in the package?

The 20 L bag, a detachable shoulder strap, and a set of 4 LOBOO quick-release straps. Everything you need to install it is already included: you don't need to add anything.

What is the difference between IPX6 and IPX7 for ALPS bags?

IPX6 protects against high-pressure water jets: heavy rain, washing, and splashes. IPX7 adds brief immersion. For everyday use and weekend trips, this bag’s IPX6 rating is more than sufficient, provided the roll-top is rolled three full turns and secured with both buckles.

Are 20 liters enough for a weekend?

For one or two nights, yes: a change of clothes, rain gear, toiletry kit, and charger will fit. For a trip lasting several days, or if you’re carrying camping gear, you’ll need 40–50 L, and it’s worth looking at the ALPS 46 L or the Wanderer 50L. LOBOO itself positions this size for daily commutes and short outings.

Can I load 200 kg onto it?

No, that's a common misconception. The 200 kg refers to the stated strength of the fabric—how much it can withstand before tearing. The load you can actually place behind the seat is determined by the motorcycle or scooter manufacturer, and is almost always just a few kilograms on the tail and 5–10 kg on a luggage rack.

Can it also be used outside the motorcycle?

Yes, the detachable shoulder strap is included. Unclip the straps and carry it over your shoulder or by hand: it is designed specifically for people who arrive at the office or gym and do not want to transfer their belongings to another bag.
