Buyers Guide

If you are looking to buy a bike saddle bag, then there are a couple of things you need to think about. If you are going on a Bikepacking trip or a long bike touring journey having a bike saddle bag will allow you to bring a lot of your gear.

When it comes to buying your next or first saddle bag then there are a few things you need to consider. Keep reading below to assist you in buying the best bag possible for your bike riding experience.


Saddle bags come in a wide range of sizes. You can get saddlebags that have very large capacities that would be perfect for long Bikepacking trips. Smaller saddle bags are perfect for road bikes or for shorter bike rides and commuting.

You aren’t limited by the capacity of the bag that you buy. But, when you are purchasing your saddle bag you need to know what you will be using this bag for.
A lot of the bags we have mentioned have a feature where you can roll the bag down and carry smaller amounts of gear.

There are options, but you want to make sure that your bag has enough capacity for the uses that you have in mind. Otherwise, you’ll end up with a bag that doesn’t fit in everything that you want.

Also, consider that some of the larger bags have a tendency to sway and wobble about when riding. Especially when they are fully loaded with heavy weight.

Seat Packs are just one of the many Bikepacking Bags you can get. Also, take a look at Bike Framebags, and Bike Handlebar Bags.

Tire Clearance

These bags fit onto your saddle post and fit behind you while you are riding. You must make sure the bag you chose has enough clearance for your tire. Not a good idea for the pack to hit the rear tire. Generally, 9-10 inches / 22-24cm clearance is enough.

Saddle bags are designed to fit on pretty much all and every type of bike, providing have enough tire clearance. Yet, it doesn’t hurt to double check the tire clearance just in case.


While you are riding your bike, you can’t always be sure what kind of weather you will be facing. If you find yourself riding through puddles, water may splash onto you and your bike.

The bags that we have mentioned are waterproof, and that is something that you need when buying a saddle bag. You want to feel confident that no matter the weather conditions that your gear will stay safe and dry in the bag.


How stable your bag will be depends several things.

Firstly, on the terrain, you will be taking your bike and bag into. When it comes to rougher and rockier terrain some bags struggle to stay still. Straps can loosen, which then makes riding more difficult.

Secondly, the design will determine stability. The way the bag straps to the seat post and seat rail will determine how much or how little the bag will sway.

Thirdly, the weight you are carrying will affect the handling of the bike and how stable it is. Smaller bags with less weight will be more stable than large, heavily loaded bags.

The vast majority of saddle bags should be able to withstand any terrain whether you are riding a Bikepacking Bike, Mountain Biking, or Fat Tire Bike.

Packing Style

There are two different types of packing styles when it comes to saddle bags. You can have a saddle bag that comes in one piece and you usually pack all your stuff straight onto the bike. While there are some bags that come in two pieces.

There is a harness bag that is constantly attached to the bike and there is a removable inner bag that you can easily take on and off the bike for packing and unpacking.

The one piece packing style is much more traditional, and you could take it off the bike to pack but that requires a lot more effort. Whilst the two piece system is a lot more convenient and easier.

By removing the inner bag you can easily fill your bag up. Both types work really well and it is up to personal preference which type you should choose.


A bike saddle bag is a really useful thing to have, as it makes carrying gear a lot easier, as you don’t need to carry any heavy equipment on your back.

There are a lot of different bike saddle bags to choose from, but my personal favorites that I recommend are the following.

The Ortlieb Seat Pack Saddle Bag is the best overall due to the very being one of the lightest on the market, It is also stable, even when fully loaded. And it is the most waterproof of all the bike seat bags in this review.

Both the bike-packing bags from Revelate Designs are also highly recommended. I love the stability of Revelate Design Spinelock 10L Seat Bag. It will not wobble, even when fully loaded. And the Revelate Designs Terrapin 14L Seat Bag also performs similarly well.

Frequently Asked Questions

Are Saddle Bags Useful?

Saddle bags are useful pieces of equipment to have. While out riding you always need to carry a couple of pieces of essential equipment like a tire repair kit and pump to name a couple.

A saddle bag allows you to carry all the essentials, while larger saddlebags allow you to carry all your gear easily. This type of bag is a better solution and option than carrying everyone on your back with a bike backpack.

What Should I Be Packing For A Bike Ride?

This can depend on how long you will be away for and the size of the bag you have chosen. However, you should always pack a pump and tire repair kit, alongside your phone, keys and wallet.

Sometimes you may want to pack some food and a change of clothes, depending on the length of your bike ride and the weather. It is up to you what you pack, but you always need to make sure that the essentials are packed, just in case something goes wrong.

Are Saddle Bags and Seat Bags the Same?

Yes, Saddle Bags and Seat Bags are essentially the same things, however, there are smaller bags that fit under the bike seats that are best suited for small items such as tools and spares. Larger saddlebags are best suited for Bikepacking style trips.
