We researched various ways to package our bicycles for checking as luggage on our flight -- from simply packing them in a cardboard bike box to securing them in a hard-shell container. The solution we settled on was purchasing soft-sided bags made by Biknd which will accommodate the bike and its wheels. The saddle and pedals are generally removed. We still had the issue of packing the bikes' luggage racks and fenders, which because of the overall weight of the packed bike bags, we opted to stick in the suitcases with our clothes, panniers, handlebar bags and other belongings.
