FAQs

Q&A

Does the bag stay secure at high speeds, especially on motorways?

Yes — our bags feature reinforced straps and adjustable harnesses designed to stay stable even at high speeds. Proper installation ensures a secure fit on the motorway.

Is the bag compatible with my motorcycle?

Yes — our bags are compatible with all motorcycles thanks to a universal strap-based mounting system.

They’re easy to fit, whether you ride a naked, an adventure bike, or a sportbike — we've tested them on dozens of models with consistently great results.

Is the bag waterproof, even in heavy rain?

Yes — our bags are made with water-repellent materials and sealed closures to keep your gear dry in the rain.

Even during prolonged downpours, your belongings stay protected so you can ride with peace of mind.

Does the bag heat up in direct sunlight?

TheRiderBag™ is built with materials that withstand outdoor temperatures.

It may feel warm after prolonged sun exposure, but it won’t lose its shape and continues to protect your everyday essentials effectively.

Can it be installed without drilling or modifying the bike?

Absolutely. Our bags can be installed in seconds using adjustable straps or embedded magnets (included).

No screws, no holes, and no modifications to your motorcycle are required.

Is the bag spacious?

Yes — our bags offer smart storage with dedicated compartments for rider essentials: gloves, tools, documents, lock, phone...

Everything fits neatly without getting in your way.

Can magnet-mounted bags scratch the bike?

Normally, yes — magnet bags can cause micro-scratches if not properly protected.
But our bags use soft, anti-friction coating and fully encapsulated magnetic surfaces, specifically designed to protect your tank.
The result: a stable hold with no direct abrasive contact.

Are the bags heavy when empty?

No — our bags remain lightweight when empty, thanks to technical materials like military-grade fabric and alloy reinforcements. You get true durability without unnecessary weight.

Can the backpacks fit a full-face helmet?


Some of our backpacks are spacious enough to fit a full-face helmet, depending on the model.

Please check the listed dimensions on each product page to ensure your helmet fits comfortably.

Does the bag stay stable when cornering or braking?

Yes — our bags are designed to stay firmly in place, even during hard braking or tight turns, thanks to a secure mounting system and anti-slip straps.
Once properly installed, it won’t budge
