Motorcycle delivery services aren't too popular in North America right now, but that could all change thanks to the Transport Hornet. The Transport Hornet is an air-powered tricycle (which looks more like a motorcycle) designed to deliver the goods in big cities.
The Transport Hornet runs off of tanks of compressed air and it has a unique storage bay that can be detached and pulled just like a piece of carry-on luggage. I believe a design like this could really give the bicycle delivery services of the world a run for their money. The Transport Hornet can carry more than a tradition bicycle delivery man and is as eco-friendly as it releases no emissions into the atmosphere.
