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.

The Topeak Bicycle 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 Trunk bags 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 this 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 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!
