The Ibera PakRak bicycle trunk bag is a large bike bag that offers plenty of storage and features that we think you will love. It is affordable and, most importantly, large enough to hold all your items. This bag's main compartment can hold clothes, a water bottle, or even a small laptop and still have room to add a few more items.

The included side pockets also provide extra room to store more items. Plus, unlike the other bags on the list, it has a rear pocket that you can use to store a few other cycling gears. The main compartment has a wide opening that makes it easy to load your items. And the hard base and padded flooring help protect whatever you stored inside from damage if you accidentally drop the bag.

It features a smart clip-on system that makes attaching it to your bike rack hassle-free. And with the reflective stripes on the sides, top and rear of the bag, it will be easy to spot in the dark. For added visibility, there is a slot provided that will allow you to mount a rear taillight.

The Topeak MTX trunk bag is like a transformer in disguise. While in it's regular form, this bag is very unassuming and looks like a small bike trunk bag. But on the inside, the space offered is massive.

Topeak MTX trunk bag offers up to 1,010 cubic inches of internal space thanks to the ample main storage and side compartments. The bag's main storage area measures 9.8" x 14.1" x 8.5 inches and has compartments that can be removed or inserted.

It is more than sufficient to hold a good amount of groceries, books, or cycling gear when you need it. Additionally, it boasts two transforming side compartments that expand into bike panniers to provide much more space to hold items. Moreover, the reflective side stripes add that little bit of extra design style and visibility needed for riding in the dark.

The only downside to the Topeak MTX trunk bag, which isn't something bad, is that it requires you to get their MTX rack as this bag doesn't use straps to hold it in place. With that said, when it is paired with the MTX rack, this bike trunk bag is as stable as your bike frame and will not move or shake once it is secured.

Overall, this is one of our top recommendations. And if you haven't bought a rear rack or considering upgrading to a much better one, get the set from Topeak. You won't regret it!

Buyer's Guide: How to Choose the Best Bike Trunk Bag

When it comes to hauling gear on your bike, a bike trunk bag is a convenient and practical choice. These bags attach to your bike's rear rack and provide additional storage space for items such as clothes, tools, or groceries. However, with so many available options, it can be tough to know which is best for your needs. Here is a buyer's guide to help you choose the best bike trunk bag for your cycling needs.

Backpack or Shoulder Bag

One of the first decisions you'll need to make when choosing a bike trunk bag is whether you want a backpack-style bag or a shoulder bag. Backpack-style bike trunk bags can be worn on your back when you're off the bike, while shoulder or messenger-style bags can be worn over your shoulder or across your body. Remember that some of them offer you the option to carry it in your hand. Consider your preference and how you plan to use the bag when deciding which style is best for you.

Waterproof Material

If you plan on using your bike trunk bag in wet weather, it's essential to choose a bag made of waterproof material. Look for a waterproof liner or roll-top closure bag to keep your items dry. Alternatively, you can opt for a bag with a removable rain cover to provide extra protection from the elements.


When it comes to bike trunk bags, durability is key. You'll want a bag that can withstand the rigors of regular use and can handle being thrown around on your bike. Look for bags made of high-quality materials such as waterproof nylon or polyester, and consider bags with reinforced corners or a hard base to protect your items.

Pannier Compatibility

If you're planning on using your bike trunk bag for longer rides or bike touring, you may want to consider a bag compatible with panniers. Panniers are bags that attach to the sides of your bike's rear rack and provide additional storage space. Look for bike trunk bags that can convert into panniers or have side pockets that can be used as panniers.

Exterior Pockets

Exterior pockets can be a convenient feature for storing smaller items that you need quick access to. Look for bike trunk bags with zippered or velcro pockets on the outside of the bag for storing items such as your phone, keys, or tools.

Mounting System

The mounting system is how the bike trunk bag attaches to your bike's rear rack. Velcro straps, buckles, and clips are all common mounting options. Consider the ease of use and stability of the mounting system when choosing a bike trunk bag.

Storage Capacity

The storage capacity of a bike trunk bag refers to the amount of gear it can hold. Consider the size of your items and how much storage space you'll need when choosing a bike trunk bag. Some bags have a large main compartment, while others have multiple smaller compartments for better organization.

Other Features

Other features to consider when choosing a bike trunk bag include a tail light hanger for added visibility, zippered pockets for secure storage, and thick padding to protect your items. A compact bag that doesn't take up too much space on your bike's rear rack may also be a useful feature and a durable bag that can withstand regular use.
