Motorcycle trailer hitch; since they can't tow much anyway. We need to haul things a short distance; like leaves to the county compost for or some items from a store, or bicycles, skiis, or even a tiny boat... all things I've seen motorcycles pull. Later, you can design a custom trailer which specifically shaped that can handle bicycles, leaves, some 2x4s or even a few sheets of plywood etc. with data about the trailer you can change range estimates when YOURS is in use.. Even smarter, you can have the trailer provide POWER (cover it in panels, or generators, or more batteries... whatever the customer gets to charge it. Be a little open and people will invent things for you.)
