How to Choose the Right Size for Your Bike

Choosing the right size of bike trunk bag can be a bit difficult, but it's completely doable with enough research. 

The first thing to think about is whether or not you already have panniers on your bike. If so, measure them and compare those measurements with the dimensions of different bags to find which one will fit best. Take into account that these bags come in a variety of sizes, including small, medium, and large, as well as lengthy and small.

Generally speaking, though, most standard-sized panniers measure at around 12 inches wide by 16 inches high by 7 inches deep, so keep this in mind when comparing measurements of different bags. Also, remember that these measurements are only a guide because there should still be some wiggle room to make sure the things you store in the bag are safe. When choosing a bicycle trunk bag, make sure it is large enough to hold everything. 

Top 7 Features of the Best Bike Trunk Bags

The best bike trunk bags are not just the ones with lots of features but with those that cater to your individual needs. For example, if you love riding your bike at night and prefer running errands in the evenings, a bike trunk bag with reflective lights would be ideal. Let’s find out if yours has them: 

Material 

Durable material is essential for a bike trunk bag because it will be rubbing against the bike frame. A bicycle trunk bag made from a strong fabric such as nylon or polyester will ensure that it lasts. 

Size 

Consider your needs and how much space you have on your bike before purchasing a bag. A bicycle trunk bag should fit over your bicycle wheel and not interfere with your bicycle's gears or brakes. What you want to carry with you and when cycling will influence the capacity of the pack.

Padding  

Padded straps are important to prevent sore spots from developing on your back or shoulders. In addition, the bicycle trunk bag should be padded to keep your bike safe from scratches or scuffs. 

Straps 

Look for adjustable straps so that the bag can fit many different types of bikes and multiple riders if necessary. 

Locking mechanism 

Find one with an easy-to-use locking system so that it's safe to leave outside when not in use. 

Stripes that reflect light 

This improves visibility at night and when the weather is bad to avoid further cycling problems. 

Waterproofing 

Nothing is worse than getting soaked in the rain with your bicycle trunk bag. So make sure you choose something waterproof so you won't have to worry about getting your essentials wet.
