That is cool but I bet it handles like a pig with the rig folded up on the rear of the bike. Leave it to the Japanese to think of this rig. I also bet it goes through rear tires very quickly.
This has been out for a while. VERY big in Europe as they want to keep the crowded lanes clear as quickly as possible. Nice idea. Can you imagine an ambulance version where your "gerny" unfolds from the back and you get "towed" to the hospital?
