Bike Seat Bags In 2023

In this article, we’re going to tell you everything you need to know about bike seat bags, we’ll not only tell you what the most popular bike seat bags look like, but we’ll also tell you how you should choose the right one for your needs, so let’s get straight to the point.

1. What Is A Bike Seat Bag?

A bike seat bag is a bag specifically designed to fit under the seat of a bicycle. It was created for a simple reason: the bicycle is an extremely minimalist form of transportation, with no space to carry anything on its own. A bike seat bag is almost a must-have for riders who want to carry their belongings while riding. Unlike a backpack, a bike seat bag is a much easier and freer way to carry a load.

What is a bike seat bag?

Throughout the long history of the bike industry, bike seat bags have also evolved in different shapes, capacities and functions to suit more needs and user preferences.

2. Main Types Of Bike Seat Bag

Bike seat bags are generally considered to be of two main types. They are made for two completely different needs. Read this section and you’ll see how they differ.

2.1 Small Type

Small bike seat bags are available for all models and are highly compatible because of their small size and easy installation. You will easily see it on mountain bikes, road bikes, gravel bikes, and even folding bikes.

Small bike seat bags are primarily designed to carry a small number of carry-on items, so if that’s the only bag you have on your bike, then you’ll need to trade it off carefully. Typically, this small bag will be used to carry emergency supplies such as inner tubes, small air bottles and tire pry bars. Small bike seat bags may be designed with a mount at the end to mount your bike’s taillight on for safer night riding.

2.2 Large Type

Large type of bike seat bag

Large bike seat bags far exceed smaller models in capacity. This is understandable, after all, these large bike seat bags are meant to carry more items. However, limited by such a large size, it’s usually only suitable for long-distance riding oriented mountain bikes, endurance road bikes, gravel bikes, and so on. If you are a folding bike user or an aerodynamic road bike user then this bike seat bag is not for you.

Large bike seat bags can carry more items. But we need to remind you: we can load more items in it, but it is better not to load too heavy items. Because the mounting height of the seat bag is under the seat, which means a higher center of gravity, if the weight is too much, it will directly affect your confidence when controlling the bike and the safety of cornering. We recommend that you load items such as raincoats, inner tubes, and small parts in this type of bag.

4. How To Choose A Bike Seat Bag?

There is a wide range of bike seat bags on the market, and we need to carefully consider our actual needs before making a purchase. We have listed some of the elements that must be considered.

4.1 Requirements For Loading Items

Not all riders need large bike seat bags. Many times, riders are simply commuting through the city or doing a ride within 50KM on the outskirts of town. They usually don’t need to carry a lot of stuff with them. In fact, they only need to carry items like a cell phone, a small amount of cash, an inner tube and a portable pump.

Requirements for loading items

When you need to carry a lot of items, it’s a different story. You must be on a long ride, or bikepacking. In this case, a large bike seat bag becomes one of your must-haves.

4.2 Types Of Bicycles

As mentioned above, folding bikes are not suitable for fitting large bike seat bags, whereas other types of bikes do not have this problem.

One detail to keep in mind is that if your saddle height is too low (the distance between the saddle and the rear wheel is too close), then the large bike seat bag may rub against the spinning rear wheel.

4.3 Size

Different sizes correspond to different loading requirements. If you don’t have the need to ride long distances, you don’t need to prepare a large bike seat bag. In the market, most of the bike seat bags are small in size and their purpose is to be installed without affecting the overall aesthetics of the bike. Moreover, aerodynamic effects are very important for bike riding and small bike seat bags do not slow you down.

4.4 Budget

Large bike seat bags are usually more expensive than small bike seat bags, especially good quality large seat bags. Although there are also very expensive models of small bike seat bags depending on whether your budget is sufficient. If you’re on a budget, try to go for a professional cycling brand such as Bontrager, or if you’re on a tight budget, go for a model made in China, which is also very sturdy and durable.

4.5 Fabrics

A good bike seat bag won’t be made of just one fabric. The process of stitching multiple fabrics together is very common in bike seat bag products. Abrasion-resistant fabrics can be used on the top (i.e., near the bottom of the seat) and sides of the seat bag to avoid damage after an accidental fall.

Waterproof fabrics

The bottom of the bike seat bag, on the other hand, needs to be made of water-resistant fabric with a hard EVA shell embedded. The significance of this design is to prevent mud and water thrown out by the rear wheel from intruding into the interior of the bag, while the EVA hard shell ensures that the bag retains its shape even when loaded with heavier items. Of course, the EVA shell itself is also waterproof.

4.6 Color

Unlike regular bag products, bike seat bags are usually used in bad scenarios, most of the time facing dirt or mud thrown up by the rear wheel. As a result, you will hardly see white or light colored bike seat bags in daily life. Most of the best-selling bike seat bags are dark colors such as black, gray, and silver. These colors are more resistant to dirt and don’t affect the appearance even if some of the stubborn dirt can’t be removed.

6. FAQs

Here are some common questions and answers for you to consider.

6.1 Are Bike Seat Bags Safe And Secure?

Yes. Bike seat bags can be fitted with anti-theft locks on the zippers. Its bag fabric is also so tear-resistant that ordinary scissors can’t damage it.

In addition, the rear part of the bike seat bag will be labeled with some reflective materials, which will reflect the light when riding at night and improve safety.

6.2 How Do I Wash A Bike Seat Bag?

We prefer that you hand wash your bike seat bag. Because machine washing may damage the fasteners and velcro on the bag.

Cleaning method: Use a shoe brush to scrub the body of the bag. Or use a wet wipe to wipe down the body of the bag.

6.3 Can The Bike Seat Bag Be Mounted On Other Parts?

No. Bicycle seat bags are specifically designed to provide storage under a bicycle seat and should not be mounted elsewhere of the frame, as this may cause the bag to become accidentally entangled in the wheel during a ride, which could be dangerous.
