1. SW-MOTECH Pro Tankbag: Top Pick
In our evaluation, the SW-MOTECH Pro Tankbag stands out for its robust magnetic mount and expandable storage. Owner feedback consistently praises its secure attachment even at highway speeds. The included rain cover and clear map pocket add practicality. However, the magnetic mount only works on steel tanks, limiting compatibility.
This bag is ideal for riders with steel tanks who want a quick-access, expandable bag. Those with non-ferrous tanks should skip this and consider a strap-mount model. The 3.0L base capacity is compact enough for daily essentials without feeling bulky.
- Magnetic mounting system fits steel tanks securely
- Expandable design with 3.0L to 5.0L capacity
- Includes rain cover and map pocket
Pros: Excellent build quality and materials; Easy to install and remove
Cons: Not suitable for aluminum or plastic tanks
2. GIVI EA101B Tanklock: Best Mounting System
We compared the GIVI EA101B and found its Tanklock mounting system offers exceptional stability. The bag snaps onto a ring that remains on the tank, making on/off fast. Owner feedback highlights its waterproofness even in heavy rain. However, the need for a model-specific ring adds upfront hassle and cost.
This bag suits riders who prioritize a rock-solid mount and plan to use it long-term. If you switch bikes often or don’t want to buy a separate ring, a universal strap bag may be better. The 4.0L capacity is generous for a small tank bag.
- Tanklock quick-release system requires specific ring
- Waterproof construction with welded seams
- Internal organizer pockets for small items
Pros: Very secure and wobble-free mounting; Fully waterproof without needing a cover
Cons: Requires a separate Tanklock ring for your bike
3. Oxford Aqua T20: Budget Friendly
Based on owner feedback and the spec sheet, the Oxford Aqua T20 offers great value. The roll-top design keeps contents dry, and the straps fit most tanks. However, we noted that the straps may require periodic tightening, and the bag can slide slightly during aggressive riding.
This bag is best for budget-conscious riders who need waterproofing and don’t mind occasional strap adjustments. If you ride off-road or at high speeds, a more secure mount is recommended. The 5.0L capacity is ample for a day trip.
- Roll-top closure for waterproof seal
- Adjustable strap mounting for universal fit
- Reflective details for visibility
Pros: Affordable and fully waterproof; Lightweight and easy to carry off bike
Cons: Strap system can shift on bumpy roads
4. Kriega Kube Tank Bag: Premium Build
Our evaluation of the Kriega Kube reveals a tough, well-engineered bag. The harness system attaches securely to the tank without magnets or straps that scratch paint. Owner feedback praises its longevity, but the 3.0L capacity is limited for those needing more space.
This bag is for riders who value durability and a clean aesthetic over sheer capacity. If you need to carry a tablet or extra layers, look for a larger bag. The harness can be left on the bike for easy click-on access.
- Harness mounting system with quick-release clips
- Cordura fabric with waterproof zipper
- Internal mesh pocket and key clip
Pros: Extremely durable materials and construction; Harness distributes weight and stays put
Cons: Premium price for a small capacity
5. Bags-Connection City Tankbag: Compact Design
From our research, the Bags-Connection City Tankbag is one of the smallest options. It sits low and doesn’t interfere with the handlebars. Owner feedback notes it’s perfect for essentials but struggles to hold even a small water bottle. The magnetic mount is strong on steel tanks but not adjustable.
This bag suits minimalist riders who only carry a phone, wallet, and keys. If you need to carry tools or a snack, consider a larger bag. The slim design is a plus for sport bikes where space is tight.
- Slim profile for minimal interference
- Magnetic mount with pull-tab release
- External zippered pocket
Pros: Very compact and lightweight; Easy to attach and detach
Cons: Limited storage for anything beyond phone and wallet
6. Rhinowalk Tank Bag: Value Option
We compared the Rhinowalk Tank Bag and found it offers a lot of space for the money. Owner feedback appreciates the multiple pockets, but some report the straps loosen over time. The rain cover is a plus, but the fabric isn’t fully waterproof on its own.
This bag is a good choice for riders on a budget who need maximum capacity in a small footprint. However, if you ride aggressively or off-road, the strap system may not hold as well as magnetic or ring mounts. Consider upgrading the straps if needed.
- Large capacity for its size class
- Water-resistant fabric with rain cover
- Multiple compartments and MOLLE webbing
Pros: Spacious and versatile storage; Affordable price point
Cons: Strap mounting can be fiddly and less secure
7. Viking Bags Tank Bag: Classic Style
In our evaluation, the Viking Bags Tank Bag appeals to riders who want a retro look. The magnetic mount is supplemented by a safety strap. Owner feedback notes the bag looks great but the faux leather can show wear and is not weather-resistant. The internal sleeve fits a small tablet.
This bag is best for cruiser or vintage bike owners who prioritize style. If you ride in rain often or need robust waterproofing, look elsewhere. The 4.0L capacity is decent for daily essentials.
- Vintage leather-look design
- Magnetic mount with safety strap
- Internal padded tablet sleeve
Pros: Aesthetic appeal for classic bikes; Good internal organization
Cons: Leather finish is not waterproof
Frequently Asked Questions
How do I choose between magnetic and strap mounting?
Magnetic mounts work only on steel tanks and offer quick attachment. Strap mounts are universal but can shift. Tanklock rings provide the most secure fit but require a specific ring. Consider your tank material and how often you remove the bag.
What capacity is considered 'small' for a tank bag?
Small tank bags typically range from 2 to 6 liters. A 2-3L bag fits a phone, wallet, and keys. A 4-6L bag can hold a tablet, snacks, or a light jacket. Choose based on your essential carry items.
Can I use a tank bag on a plastic tank?
Yes, but only with strap or ring mounting systems. Magnetic bags will not stick to plastic or aluminum tanks. Look for models with adjustable straps or a Tanklock ring compatible with your bike.
Are tank bags waterproof?
Not all are. Some have waterproof zippers or roll-top closures, while others include a rain cover. Check the specifications. Fully waterproof bags are better for wet climates but may cost more.
Will a tank bag scratch my paint?
Magnetic bags can scratch if dirt gets under the magnets. Use a protective film or clean the tank regularly. Strap and ring mounts are less likely to scratch if installed correctly. Some bags come with a felt backing.
Our Verdict
After researching and comparing, our top pick is the SW-MOTECH Pro Tankbag for its secure magnetic mount, expandable design, and overall quality. The GIVI EA101B Tanklock is a close runner-up for riders who prefer a ring-based system and need waterproofing. Choose based on your tank type and storage needs.
