A bike bag is a constructed from material, and usually has a layer of foam for extra padding. Some have a resilient outer, to prevent ripping in transportation, and more expensive versions will have wheels as well as a handle for moving around the airport.

5 of the best bike boxes and bags

Bike Bags are fairly light – usually just a couple of kilogrammes, which makes them easier to get in and out of cars and removing a lighter bag from the carousel is a lot less intimidating than grabbing a box. They are also squishable – which makes fitting a bike bag into the car much easier than a rigid box.

The other major benefit of a bike bag is cost – these are generally around £100, some are significantly less, others can cost more – you’ll pay more for extra padding, a stronger exterior and more padded storage pockets.

The downsides on bike bags is that though they meet all airport luggage requirements, they are not as strong as rigid bike boxes. You can add to the protection offered by wrapping your frame and components in bubble wrap but a box will offer greater bash proofing.

Review: Polaris Axial Pod

The lower weight does mean you will likely come way below airport maximum weight, which means if you like you can fit some extra kit inside the bag. This said, unlike a rigid box, which allows you to pack kit in neatly around the bike, extra bits included in a big will be free to float around and could get dirty or damaged unless well stowed. Fabric straps will also be limited to the weight they can carry, so you won’t be able to load your entire suitcase in there.
