Things To Consider When Buying A Bike Seat Bag

  • Storage Capacity

I consider this feature the most important one before purchasing a bike seat bag. I used to have a bike seat bag with the wrong choice. I had imagined the bag was big enough for my items but it wasn’t. Yes, I hadn’t researched the capacity.

There are some Bike seat bag brands giving you several options of size and volume. So, take care of them. Basically, the capacity can vary from 0.41 L to 11 L- a vast change. For example, Blackburn Grid , Topeak Aero has a small size of 0.4L while the large one is up to 1.9L.

  • Material

Most of the modern bike seat bags underline water-resistant features. Therefore, there have been PVC, nylon, polyester, polyethylene, and TPU used. Coating material for ensuring waterproof is necessary.

Polyester is considered to be rather durable and generally resistant to stretching. If you are a fan of this material, then WOTOW is the good one. Nylon is a synthetic fabric and known for its low absorbency rate which is also common for making seat bags. (1)

REI Co-op Junction uses bluesign® Ballistic nylon while Blackburn Grid has 210t nylon ripstop and 210d polyester for their waterproof material.


  • What should I put in my bike seat bag?

Some breakdowns on the road require you to have good preparation. That’s why a seat bag was born. There are 10 essentials for a good bike, a long bike, a picnic, adventure, etc.

Inner tube, tire levers in case of getting a flat, multi-tool, quick link for broken chain. Patch kit, valve extender, CO2 inflator, tire boot, spare cash, personal items, and your phone. For a more careful preparation should be a mini pump, zip ties, and cleaning wipes for your grease hands.

  • Which size of the seat bag should I choose? 

It depends on your ride intent. If you have long journeys, usually on roads and expeditions, then a large size of over 10 L is most suitable for your tent, raining coat, and clothing besides the basic repairing tools. (2)

A routine short ride might require not much capacity except the necessities like an inner tube, CO2 cartridges, and multi-tool. I would recommend you not carry the large size with your carbon seat post. WOTOW Rear Seat Bag is my favorite for pannier rear rack style, in which I don’t have to pay attention to the stiffness of the seat post.

  • How can I attach a saddle bag?

You can choose the pack with a strap mount and snap-on buckles for the 0.4 L to 2 L capacity. This utilizes the lift force from the metal bars under the seat and the seatpost. In the same manner but with the size of 11 L to 15 L, they need more strap mounts to reinforce the keep.

If you have a rear rack, the problem will be more convenient, just put your bag on it then wrap by the straps. Then it’s done. However, Seat Capsule Premio allows you to make it simpler with only BOA closure to attach the bag to the saddle rails. This helps minimize bodily contact.


If price is the main concern, then Topeak Aero with 3 options of capacity is the best in many. Quick access and fashionable style please all the fastidious customers.

ROCKBROShas a 3D shell shape and is also stylish with 2 options of color decoration. And the lifetime warranty attracts you more. Sometimes, you need bigger bags to go with your bike.

Sturdiness and extra-large up to 16.5 L will require a bit expensive payment but Ortlieb and Evoc Boa  are right there for you. Scroll style as LEZYNE Roll Caddy gives you more compact storage for your favorite commuting.
