Actually, during WWII, I recall the allies had a whole paratrooper division that were airborne, and parachuted along with their bicycles, to make them more mobile.
I believe the bikes folded up while airborne, and upon reaching the ground, the bikes were unfolded.
They were heavy-duty bikes designed to transport men and munitions.
There is currently a model "paratrooper" bike available for retail sale.
Thanks for info.
Bikes are great as long as you’re not going cross country.
