What to Look for When Buying a Bike Trunk Bag


  • Material

When looking for a great product, the number one consideration is the material used. The construction and longevity of the bag highly depend on the material used. You can opt for those made of PU leather, Oxford fabric, nylon, and polyester. These are some of the top-tier materials for trunk bags.

  • Storage Capacity

Another thing you should consider is the storage capacity. Before making your purchase, assess your needs. If you are a heavy packer, you can choose a trunk bag with 13-25 liters storage capacity. On the other side, if you want to keep it light, there are bags with an 8-liter storage capacity. These are often referred to as narrow bike trunk bags.

  • Versatility

Most bike rack trunk bags available in the market today are multifunctional. You should pick a product that is not only good as a trunk bag but can also be used when you are off the road. Meaning, you can use them as bike panniers, shoulder bags, commuter bags, and handbags as well. In this way, you can maximize the money you spent on the bag.

  • Comfort

Of course, you should pick something that provides convenience and comfort. You can choose bicycle trunk bags like the Ortlieb trunk bag that have an excellent padding system to provide you the utmost comfort. The adjustable strap that comes with bags for back of bikes should be padded too. It will be easier to carry if you convert it into a shoulder bag.

  • Safety Features

Most bike trunk bags we have listed have additional safety features. Aside from being a stylish bike trunk bag, they have reflective stripes and tail light attachments so you can use them at night.

How Do I Attach My Trunk Bag to My Bike


Attaching your bag to your bike is easy given that the product you pick has an excellent attachment system like the Rei bike trunk bag. Most of the top-tier bike trunk bags today come with secure velcro straps for safe and secure attachment. You can use two velcro straps for the back attachment, and another strap for the front attachment.

What is the Difference Between a Rear Rack Top Bag and a Trunk Bag for Bicycles

Many riders assume a difference between a rear rack top bag and a truck bag. It’s easy to make this assumption because bike bag manufacturers use both terms simultaneously.

However, any rear rack top bag will serve the same purpose as a trunk bag. These terms both refer to a biking bag on the rear rack. So don’t hesitate to purchase a trunk bag for bike use when looking at options to mount on your bike’s rear rack.

How to Secure a Trunk Bag on a Bike

There are several different ways to secure a trunk bag. It makes sense, considering how many styles and shapes are available to bike owners. I mean, it wouldn’t be possible to secure a pannier trunk bag similar to a small bike trunk bag like WOTOW’s Bike Rack Bag.

In this case, the issue would be with panniers being too big. These trunk bags would probably end up flying off the back of your bike when it’s least expected – obviously, not an ideal situation for any rider.

Most manufacturers make it easy by including a mounting system with their bags. So the buyer proceeds to follow instructions and secures the carrier onto the bike rack. A few popular methods involve using velcro straps or a hook-and-loop fastener system.

Buyers will even come across quick-release designs, such as Ibera’s Quick-release Bike Trunk Bag. So it becomes a little bit of a dealer-choice situation. You’ll need to choose an attachment method that most suits your ride when buying a bicycle trunk box or bag.

How Long Does a Bike Trunk Bag Last

The longevity of any bicycle rear trunk bag will depend on its overall construction. But generally, I’d wager on the most trusted ones lasting several years or even a decade in some cases. So buyers would be wise to research each option’s durability before making a final decision.

How does a buyer do this research? My starting point would be reading customer reviews and asking fellow bikers for recommendations. These reports should be enough to help paint a picture of which option can last a long time.

But if I had to recommend a durable option right now, it’d have to be a product like Lixada’s Insulated Bike Trunk Bag. This waterproof trunk bag has shown an excellent ability to withstand various issues that could damage most options.

How Much Weight Can I Put in My Trunk Bag

The bike truck bag features several storage capacities. Depending on the construction of the bike trunk bag backpack, you can put weight from 8 liters up to 25 liters. It greatly depends on your needs and how many items you want to store in your bag. A large bike bag is great for bikers who love to bring most of their items when on the road.

Bike Trunk Bag vs Bike Pannier Bag: What’s the Difference

Trunk bags and pannier bags are used for almost the same purpose. Both types can be attached to your bike, and store your much-needed essentials. Trunk bags are great during short travels, as they can hold enough items. Panniers are better when you spend week-long travel on the road. Bike pannier bags can keep your bike well-balanced once you have attached them to your bike.
