I am not an engineer or motorcycle enthusiast and have no relevant experience in marketing vehicles.  Nonetheless, I am certain that an inexpensive plug-in motorcycle would sell like hot-cakes.  My random googling indicates that this type of merchandize does exist:  there are plug-in motorcycles for sale.  But they are all very expensive and/or ugly.

You take a Tesla motor, reduce it to a third of its size and power, stick two wheels on it, and sell it for $5k.  Don’t waste your time trying to make it look like a Ducati. Someone ought to be doing this, amiright?
