From time to time, I have read questions about fitting a bike in a suitcase for air travel, so I started to work toward solution about three years ago. I wanted to have to have a case that was within the airline limit of 62" to avoid oversize-bag fees, it had to be very durable and lightweight, and it had to be easy to convert into a trailer. So, we developed a 30" x 20" x 11.75" polypropylene case that holds our 20" Origami Crane 8 without too much dis assembly. We also developed a trailer kit that fits neatly inside with the bike and takes only minutes to assemble.
I wanted to make this all very practical, so we have a 22" carry-on bag for your clothing and other items as well. These are fully-lined premium cases that can be used for all travel needs, not just your bike.
Plus, we used colors that will make the bags easy to recognize and very attractive. Let me know what you think.
