Storage Capacity

I feel that this is an essential aspect when buying a bike trunk bag. Since it is used to carry all the essentials needed in a bike ride, you need to know the storage capacity of a bike trunk bag.

Since every bike trunk bag comes in different sizes, you must know the stuff you are carrying along. From there, more or less, you will get the idea of the storage capacity you need to keep all your bike essentials. Also, you must consider pockets and compartments as additional storage spaces.

Durability and Toughness

These two factors should go hand in hand as this indicates the quality of a bike trunk bag. The durability and toughness can be determined by the type of materials being used in the manufacturing process. I suggest looking for polyurethane (PU) and polyester materials because these are some of the popular fabrics used, which are solid and tough.

Another way to test the durability is to look for water its resistance features. If a bike trunk bag can prevent water entry when it is raining hard, or the bike is navigating in rivers or trails with water, that is a good indication of its toughness and durability.

Ease of Installation

I will go for a bike trunk bag that can be installed in the bike rack easily. My suggestion is to look for the strap Velcro system because this mounting system is known for its easy installation process and removal. As a biker, it is essential for you to easily mount the bike bag and remove it in the rack if needed especially when resting and the need to remove the bag is essential for security purposes.

Versatility and Flexibility

What if the bag is removed from the bike rack? How will you bring it? Most bike trunk bags come with a versatility feature that enables you to convert them into different type of bags. Some bike trunk bags can be converted into a traditional handbag, messenger bag, shoulder bag, and even messenger bag. The upside of having this feature is carrying the bag easily once removed from the bike.

Additional Accessories

There are bike trunk bags that provide additional bike accessories in the product packages. Some are giving rain covers, straps, bike tools, tail lights, among others. My point is if the bike bag is offering these add-ons, then take it. All of these accessories will be beneficial once you hit the road.
