Figuring out what size Bikeflights Bike Box you need for your mountain bike is similar to figuring out what size box you need for any other bike, and you are responsible for measuring your bike to see if it will fit. Learn more here: What size Bikeflights Bike Box do I need? 

You may have up to three box options.

Bikeflights Bike Box Medium (BBM) - You will have to remove both wheels plus many other components like bars/stem, pedals, rear derailleur, rotors, seat and seat post. An advantage to this box is it gives you the best rates because it’s the smallest option for full-size bikes. This also saves you money when shipping internationally. However, not all gravel, road and cyclo-cross bikes will fit in this box. Frame size and handlebar size and shape can prevent a bike from fitting into this box.

Bikeflights Bike Box Large (BBL) - With this easier-to-pack box, your rear wheel stays on for most bikes. You will still have to remove some other components but not as many as for the BBM. You may have to remove your handlebars depending on their size and shape. The BBL ships well domestically and internationally.

Bikeflights Bike Box Extra Large (BBXL) - With this easier-to-pack box, you remove both wheels, but you can leave most road/gravel bars on. Often, you can even leave your aerobars on! This is a great option if you want to keep your bars and stem in place while shipping. It’s also great if you have an integrated (one-piece) bar and stem or if you want to stash a spare set of wheels in your box. This box ships best domestically; it is too large for some international shipments, depending on where you are shipping to and from.
