How we evaluated these tank bags

We judged every bag on six things riders actually care about:

  1. Mounting security: Does it stay put over bumps, braking and highway speeds?
  2. Paint safety: Does the base protect the tank, and is it easy to keep clean?
  3. Capacity and access: Can you reach a phone, wallet or map without stopping?
  4. Weather protection: Water-resistant fabric, taped or covered zips, and a rain cover.
  5. Build quality: Fabric denier, zip type, stitching and handle strength.
  6. Value: What you get for the price compared with similar bags.

We road-tested the AllExtreme tank bag, and it proved worth carrying. It keeps your phone or map in view so you don’t have to stop to check directions. It holds a water bottle, phone and small essentials within easy reach, and it has room outside for gloves or a jacket. The soft base helps protect your tank’s paint, so you can ride with everything you need close at hand.

We also compare AllExtreme fairly against other brands. Where a competitor does something better, we say so.

Detailed Product Reviews

1. AllExtreme EXFTB01: best value magnetic tank bag

Key specifications

  • Mounting: Universal fit mount with strong magnet and nylon base.
  • Capacity: 21 litres
  • Fabric: Nylon Fabric
  • Weather protection: Raincover included, water-resistant body.
  • Zips and hardware: Reinforced stitching, heavy-duty zippers, and quick release adjustable straps.
  • Features: Touchscreen phone pocket, map pocket, reflective strips, shoulder strap.

Real-world performance

On the road, the AllExtreme EXFTB01 bag stayed firmly in place over bumps and broken patches, so we never had to stop and readjust it. It didn’t shift at highway speed, which let us focus on the ride instead of what was sitting on the tank. With 21 litres and several pockets, gloves, a wallet, a charger and documents were easy to reach, so we spent less time rummaging at stops.

In wet weather, the rain cover kept our belongings dry, and the bag was ready to go again after the shower. When we stopped for the day, it came off the tank quickly, and we carried it by the handle or shoulder strap.

Pros:

  • Strong magnets grip a metal tank securely, and the bag detaches in seconds.
  • 21 litres of storage with multiple pockets keeps gloves, a wallet, a charger and documents organised and within reach.
  • A rain cover is included, so the contents stay protected from rain, dust and dirt.
  • A carry handle and detachable shoulder strap let you use it as a travel bag off the bike.

Con:

  • The magnetic mounting only works on metal (steel) tanks, so riders with plastic or alloy tanks need a strap-mounted bag instead.

2. ViaTerra Oxus Magnetic: lowest-priced magnetic option from a premium brand

Key specifications

  • Mounting: Magnetic. A strap-based Oxus version is also sold.
  • Capacity: 13 L
  • Price: ₹2,799
  • Fabric and weather protection: Polyester fabric with water-resistant.

Real-world performance

At 13 L, it suits a phone, wallet, gloves and a few small essentials, and ViaTerra’s own luggage guides pair it with tail bags and dry bags for longer trips. That makes it a good fit as the “front” part of a larger luggage setup, but its capacity is smaller than the 21 L AllExtreme magnetic bag, which gives you more room on its own.

Pros: Large 13 L capacity for its price; magnetic quick fit; available in a strap-based version for non-steel tanks.

Con: The magnetic version only works on steel tanks.

3. ViaTerra Fly Magnetic: everyday magnetic bag

Key specifications

  • Mounting: Magnetic. A non-magnetic Fly version is sold at about ₹2,899.
  • Price: ₹2,899
  • Capacity, fabric, weather protection: 22 L, polyester fabric, and water-resistant.

Pros: Both magnetic and non-magnetic versions are available; established brand; free shipping on several retailer listings.

Con: Priced above the Oxus Magnetic. Stock is limited at some retailers, so check availability.

4. ViaTerra Viper Pro: best premium tank bag for touring

Key specifications

  • Mounting: Buckle-based quick-release system, so it does not depend on a steel tank.
  • Capacity: 12 L, expandable
  • In the box: Mounting harness, shoulder strap and external rain cover
  • Price: ₹5,999

Real-world performance

Buckle mounting is designed to make refuelling stops easier, and the included rain cover is useful on monsoon or mountain trips.

Pros: Works on any tank material; rain cover, shoulder strap and harness included; expandable capacity; quick release for fuel stops.

Con: At ₹5,999 it costs more than double an Oxus Magnetic.

5. RoadGods Small Magnetic Tank Bag: compact city option

Key specifications

  • Mounting: Magnetic, with six strong magnets
  • Features: Touchscreen-compatible pocket and reflective strips
  • Price, capacity, fabric: Durable material with 2.5 L capacity at ₹1,399

Pros: Touchscreen pocket for navigation; reflective strips for visibility; compact size suits short rides.

Con: Small size limits long-trip use, and magnets need a steel tank.

Buyer's guide: how to choose the right tank bag

Magnetic or strap-on: which should you choose?

Magnets grip steel only. If a fridge magnet does not stick to your tank, a magnetic bag will not hold either. Many newer bikes have plastic tank covers or alloy tanks. In that case, choose a strap or buckle-mounted bag. Some riders also add a safety strap to a magnetic bag for rough roads or heavy loads.

Feature Magnetic Strap or buckle
Fit time Seconds A few minutes
Works on plastic or alloy tanks No Yes
Holds heavy loads Moderate Better
Best for Steel tanks, short trips Touring, any tank

Will a tank bag damage my paint?

It can, if grit gets trapped under the bag. Wipe both the tank and the bag base before each ride. A soft lining on the base helps. Many riders also add clear paint-protection film under the footprint of the bag.

How much capacity do you need?

  • 5 to 8 L: daily commute (phone, wallet, gloves, power bank)
  • 10 to 15 L: weekend and touring rides
  • 15 L or more: expandable bags for multi-day trips

Check the bike's handlebar swing before buying. The bag should never block the full steering lock or the fuel cap.

Fabric, zips and weather protection

Denier (D) describes fabric thread thickness. Higher numbers usually mean tougher, more abrasion-resistant fabric. A 600D polyester body is common for value tank bags, while heavier fabrics cost more.

Water-resistant does not mean waterproof. A rain cover is the simplest way to protect gadgets and papers. Look for covered zips and stitched seams that do not leak.

Features worth paying for

  • A clear, touchscreen-friendly phone window
  • A map or document pocket
  • A padded or soft base
  • A strong carry handle and shoulder strap
  • Reflective strips for night visibility

Frequently Asked Questions

Do magnetic tank bags damage the paint?

Not by themselves. Damage usually comes from dust or grit trapped between the bag and tank. Clean both surfaces before riding and consider protective film.

Will a magnetic tank bag work on a plastic or aluminium tank?

No. Magnets only grip steel. Use a strap or buckle-mounted bag, or a bike-specific mounting ring if the maker offers one.

What size tank bag is best for a daily commute?

Five to eight litres is enough for most commutes. Choose a larger, expandable bag only if you ride long distances regularly.

Are tank bags waterproof?

Most are water-resistant, not fully waterproof. A rain cover or a dry liner is the safest option for heavy rain.

Do AllExtreme tank bags come with a warranty?

Warranty depends upon the model number. For more information on warranty on AllExtreme tank bags, you can connect with us through our official email or phone number listed on the website.

Final verdict

Choose a magnetic bag if you ride a steel-tank bike and want quick on-and-off use. Choose a strap or buckle bag for plastic or alloy tanks and for touring. If price matters most, start with the AllExtreme Tank Bags Range.
