$this->bbcode_second_pass_quote('SeaGypsy', 'A') really big chunk of the tag is in the initial R& D, payback. If someone in China figures these out they will become cheap very fast.
This is the case for virtually all EVs on the market. NRE costs for EVs are high, even though per unit cots would be lower than those of gasoline cars in volume. The biggest expense is the battery, and mass production of LiFePO4 in China has yielded $250/kWh if bought in bulk, and 2,000 cycles to 80% discharge. I last ran my car on 48V used sealed PbA pack of near-dead starter batteries when I was last able to work on it, a Soliton 1 is waiting at a relatives house for installation(it was tested with a ReVolt controller), and once road legal, I will be ordering the 300V 100AH CALB pack. My car will have cost less to build in parts than this motorcycle will cost to buy, and get 200+ miles range real world 70+ mph with performance to embarrass many $40,000 "sports cars".
It is a two seater, but the same principles of streamlining and other load reduction can be applied to a sedan just the same. Check out the "Solectria Sunrise". Imagine a 96V 100A, LiFePO4 version geared for 80 mph top speed, with an inexpensive dc motor setup(perhaps start mass producing Netgain 11" motors and use a controller of no more than 400A). It would get Nissan Leaf like range, and cost about 1/2 as much with regard to the size of the battery, while sacrificing none of the utility. A $12,000, 80-mile range and $25,000 200-mile range EV are perfectly possible. People have done better for cheaper with widely available off the shelf components and a donor chassis. Dave Cloud was able to get 200 miles range with a lead acid powered Geo Metro modified with a streamliner body shell.
Meanwhile, Iran is getting ahead of the U.S. when it comes to EV implementation among the national industry; they have 3-6 minute rapid chargers:

Can't get that one in the United States! This is especially ironic given that the battery technology that makes this possible was developed in the U.S. more than 10 years ago.
Our government is about to go to war with them on Isreals behalf against our will to help secure the access to oil by multinational corporations, oil that we should be trying to reduce our dependency upon, yet recklessly waste taxpayer funds to do the opposite with near endless subsidy financed by working and taxpaying Americans.
Peak oil makes all of that much worse.
EVs were needed last decade, and were possible 2 decades ago. This motorcycle is just another illustration of what small start-ups are capable of in the face of crushing regulation imposed upon them by the auto industry conglomerates that want to see them fail so that the conglomerates can continue the status quo.
