The first thing you'll notice about the Biknd Helium Bicycle Travel Case is that it has air bags for your bike. We should note, by the way, that it doesn't use helium in any way -- just air. The name 'Helium' stems from the lightness of the case. It weighs only 24 lbs empty, and considering the level of protection it provides for your bike, that's darn light.

The air bladders are a big part of the story, but many less obvious details make the Helium Travel Case one of the best values in protection per dollar for your bike. For starters, it uses super tough 900 denier ballistics nylon and 1200 denier polyester Oxford cloth on the outside. At the stress points where the hubs lie inside the bag, tough plastic shields are used to protect your hubs and offer protection for the bag as well, since this would be a prime spot for abrasion if left unprotected. Similar plastic shields are used on the inside end of the hubs as well, and they're strapped into place so they'll never fall off during transport. On the subject of wheels, the Helium is unique in that it can store two pairs of wheels with the bike. So go ahead, take your aero wheels and your lightweight wheels for the days when you'll be high in the mountains.

The Helium Travel Case is easy to load because it zips open to lay completely flat. You'll have easy access to the fork mount -- no more finagling deep inside a dark box to secure the fork tips to the skewer block. Biknd includes pads for the fork leg, stem, and drivetrain to protect your bike's finish from scratches or abrasion. As you fold the caseBiknd Helium Bicycle Travel Case  Detail towards the secured bike frame, the inflatable bladders fold over the wheels on either side of the bike, separating them from the frame. And once the case is all zipped up, you'll use the included pump to inflate the pneumatic padding to fill the space between the wheels and frame. Other details include nylon sleeves to keep the wheels from abrading each other and a nylon rear hub spacer to protect the rear dropouts.

The Biknd Helium Bicycle Travel Case has casters to make transport through the airport easy. It will accept road bikes up to 64cm size and mountain bikes up to 45" wheelbase. In most cases, you will need to remove your rear derailleur from the bike frame. When assembled into full size, the Helium Case is 33.5" x 50" x 12". When not in use, the Helium shows off one of its most desirable features -- it packs down to a fraction of its assembled size. It's easy to stow in the corner of a hotel room or in the closet behind your jackets.

  • Network of internal partitions inflates with a helium pump, which provides stability and protection at a lower weight than other systems
  • Special compartments accommodate an extra wheelset as well as your helmet, shoes, and other essentials
  • 360-degree opening allows you to pack your bike with only minor disassembly and without changing the adjustment of its components
  • Fits easily in the trunk of a compact car

Great Product!!

    I bought this Travel Case to ship my CX bike across the country. It worked great, about 7 months later I decided to ship my Cannondale Scalpel to St. George UT, so I had an adaptor made so I could bolt the Fork-Up lefty adaptor in and what do you know? It worked GREAT. No Damage. The following year I shipped my Fat Bike to Salt Lake for USA Cycling Fat Bike Nats and all I had to do was change the Fork-Up adaptor to fit the Fatty and the frame went both ways with no damage. Of course the fat bike required two Bike Cases, one for the wheels. 5" tires are a different matter! I highly recommend this travel case!!

    Safe Travels!

    Unanswered Question

    I really like this bag, however, i can not find a video or instructions anywhere on how to put a FS MNT bike into this bag!!! ive searched for over an hour and nothing.

    I had to give up and jut figure it out. I had to take off my FR suspension and disconnect the rear shock. this allowed me to raise the rear arm some so it would fit into the bag. After i got the bag off the plane, i noticed a wear mark where the rear of the frame was about to puncture through, im hoping my frame is bent :( will check in the morning.

    Please help or post a legit video of a FS bike be installed into the bag! I ride a Specialized Camber 26er...Please help i dont want to buy a different bag

    Great innovative product

    • Familiarity: I've used it several times

    Good job Bikdn, this case really impressed me. I used many cases since I'm doing competitions and it's the first time I'm not nervous for my Specialized S-works DI2. Also, the 360 degree opening is really usefull and the airbags give a ultimate protection to my bike.

    Continue your doing a great job !


    • Familiarity: I've used it several times

    This travel case is just awesome. I used it for the last 2 years for traveling to all the Ironman I participated and each time everything went really well. No scratch on the bike and you can take two pairs of wheels.

    As I see the company have really improved the airbags resistance. My friend bought one before me and it seems we don't have the same bladders. (He asked the company and they sent him two free replacement)

    I would definitly recommend this case for the durability, the design, the protection and the customer service.


    Bad Product

    • Familiarity: I've used it several times

    Don't by this case. I have gone through three air bladders. They don't puncture they just leak air at the seams. The bladders are poorly designed. Very unfortunate as this is an extremely expensive bike case and the bladders should have been thoroughly tested. Three flights later and this case is collecting dust. Not sure if Back Country will take it back, guess I should try.

    BTW -- the airline bag guys will rip the front pull handle off on your first trip, recommend unbuckling prior to turning the case over to the airline for handling.

    Not impressed....twice

    • Familiarity: I've used it several times

    I purchased two of these bags for my husband and myself for travel within the US. On our first trip, my bag lost a caster wheel. I got a replacement from biknd.....then I traveled alone - and one entire caster mechanism was ripped off the bag....where it was riveted on Oh and one of the seams opened....about a 2 inch long area. I was able to take the bag and have the local shoe repair person restitch the seam....but as far as the wheels....useless. Who wants a bag that you can't roll. Very disappointed in the wheel mechanism. The rest of the bag works great - never had a scratch on a frame.

    Lost caster wheels while traveling

    • Familiarity: I've used it several times

    The bag is really nice. However on my second flight I lost a caster wheel. On the third flight I lost the other caster wheel. I think I am going to install my own, something more secure than trying to get a replacement. Otherwise a nice case.

    Hello, I am interested in this Biknd Helium...

    Hello, I am interested in this Biknd Helium Bike Travel case. I saw your post at Amazon. From other sellers, I noticed that the case comes in different sizes, such as Small, Medium, Large and XLarge.

    I have a road bike that is 55cm in size. Which size would fit?

    RE: Shipping

    What is the approx shipping cost to Hong Kong? I can be reached at

    Thank you.



    Hi Selena,

    There is only one size of Biknd Case.

    As long as the measurement going from the bottom bracket to highest point of the seat tube is 68 cm or less you will be fine.

    Hi Selena,

    Avoid for the Cost

      The bag is good at only few things:

      1. Rolling efficiently through the airport
      2. Packing it is fast and simple
      3. Light weight
      4. Small easy to transport

      This is where it goes wrong:

      1. Construction quality is poor on seams and exterior nylon is not a hi denier to with stand the abrasion of travel and airports. After one trip the seams were bulging apart, the exterior handles are coming unstitched, the glued interior is coming apart from the edges of the plastic base plate.
      2. The air bladders don't actually hold air? What a great idea to have air protect your expensive bike while traveling however, each time I retrieved the bike from the baggage claim it was empty. TSA checks every bike bag and therefore you are not allowed to watch the process. They do not simply open the zipper at the top at look inside. The entire bag comes apart and the air is let out so that it can be zipped together again while deflated.
      Upon returning home I inflated the air bladders and within a few hours they had half the amount of air in them while packed with the pressure of a bike contained in the case. Bottom line, no air no protection for your bike.
      3. The wheels are placed on the exterior of the air bladder with very little padding to protect from the case being stacked or tossed. This is also something that doesn't seem well designed to expose the wheels to absorb all the pressure and weight while its being tossed around. A pair of race wheels with no padding, not a great plan in the packing method of the case.
      4. The rear of the case has zero protection for the rear der hanger or drop outs. Zero, none zero which meant I had to pack the case with more padding and try to protect the rear of the bike. This is absolutely not acceptable. It does not give good piece of mind when you open the case and it has no air the the rear der hanger is bent because the bike case doesn't have padding or a ridged area on the rear of the case for additional protection.
      5. The straps have to act as a handle as well. This is not very well thought out. No handle on top means the straps act as the conduit for baggage handlers to throw the bike around. This means poor construction yields seams stressed beyond measure within the first trip.
      6. Overall this is a better case than some I have used traveling with my bikes however for the cost and overall condition of the case after use, I would not suggest this case at even half the cost.

      Excellent information for customers. Well thought out review.


        This product is an example of good idea with terrible execution. It is easy to get a bike in the bag. The problem is that one does not purchase a bag to simply put a bike in it, but to get it from one place to another. Here are the things that went wrong on one round trip with one layover:
        1. The clasps that attach the handle to the rest of the bag tore - the high quality nylon did not year, but the $0.01 cheap thread that is used to fix the nylon to the case did not stand up. Brought it to a cobble who fixed it for $25. He laughed when he saw the quality of the stitching.
        2. Air bladder - only works if it holds air. Mine did not hold air on either trip. ON the way back I actually sat there and watched the TSA guys open and close the case to make sure they didn't let the air out . They did not.
        3. Lost the wheels one the bottom of the case. Wheels are awesome, so awesome that I am giving this bag another shot. I was so happy wheeling my bike into the airport on the way there. On the way back it was a slog as I had to drag it.
        4. The foam pad in the bottom of the case came unglued. The glue job was ridiculous.

        Oh yeah, as a result of the bag getting deflated my mountain bike wheel suffered about $80 worth of damage - bent rotor and untrue wheel.

        Yes - airlines are rough, but a $600 bag should protect the bike. I will try an exchange. If I have any issues I am sending back and giving a one star review. BKIND, if you read this and would like a video of my expereince, please let me know. Again - like the design, just don't use such cheap materials in critical places - especially the handle!

        Air cushions go flat

        • Familiarity: I've used it several times

        Im first biknd case air cushions went flat on the flight to S.A and my rims got bent! I sent the case back to BC and they traded it no questions asked! My second case had the same problem luckily my bike wasn't hurt on this flight! the case is over priced and is not safe to protect your bike!

        Great Bike Bag

          This was my first bike bag, and I would highly recommend it. I transported my bike from Singapore to Toronto, with 2 sets of wheels. I think it's probably one of the few bags that will allow for 2 sets of wheels. It was very easy to use, and it takes no time to re-assemble the bike. I am not a very good mechanic, and I basically just followed the instructions... and had no problems. I was considering between a hardcase and this, and am glad that I picked this bag instead.

          Bikeradar says they managed to fit a medium full suspension in with room to spare. They also note " through-axles will requires (sic) dropout adapters, and some full-suspension designs will require you to flip the fork around and possibly deflate and compress the rear end."
