Whatever you do, try to make sure that the bike's place does not require moving the bike for loading or unloading freight and does not take away space for freight. That doesn't leave many options. I am still amazed how many forklift drivers comment that my van is so easy to load, because I don't have to unload things and rearrange things to make the freight fit. A recent customer described how he had to reload a cube van three time while the driver rearranged personal property to include a swimming pool for the dog.
