Choosing the right bike trunk bag is much easier when you know what you're looking for. Here are some things that you should consider before choosing a bike trunk bag:

• Bike Model: Some bikes might not have a rear rack or the capacity to bear weight because of their design. For example, mountain bikes can bear more weight than certain sports bikes. Always choose a trunk bag accordingly.
• Durability: A fragile trunk bag will only betray your trust at the worst possible time. Always choose a durable bag, made with the best and most versatile materials.
• Waterproofing: Biking adventures are often hampered by rain, moisture, and heat. Choose trunk bags that are waterproof to get rid of that hindrance. Water-resistant bags are good but look for completely waterproof bags for the best experience.

The bags on our list offer all of these perks and more. The Dayliner Trunk Box in particular offers great space, durability, waterproofing, and organization. It also attaches easily to most bikes, which gives it great value over price.

Bike trunk bags rely on buckles and straps to the rear rack. For example, two wheel gear trunk and rear rack bags come with velcro straps that wrap around the rear rack bars.

Other trunk bags may have different mounting systems. One example is Ortlieb's top-lock mounting system, which latches onto the rack. Overall, most bike trunk bags are very easy to attach to a bicycle rack.

Some even come with removable shoulder straps for off-bike mobility. We highly recommend going for these trunk bags to make your life easier.

Bike trunk bags offer great value, but you can make them even better with the right complementary items. 

Here are some things that you can add:

1. Rain Cover: Most trunk bags are waterproof, but a rain cover adds extra protection. It's a great way to insulate your items from the elements.
