Yamaha unveils zero-emission electric motor scooter

July 14, 2010
Japan's Yamaha Motor President Hiroyuki Yanagi stands next to the company's new electric commuter vehicle EC-03 (50cc License Class) during a press preview in Tokyo.

Japan's Yamaha Motor unveiled on Wednesday a zero-emission electric motor scooter for city use that it said could travel five times farther than a gasoline model for the same cost.

The EC-03 can travel 43 kilometres (26.6 miles) on a single six-hour charge from a household power outlet, which costs about 18 yen (cents) in Japan, far less than the cost of powering a conventional 50cc scooter, it said.

Yamaha will launch the e-moped on September 1 in Tokyo, and a month later across Japan, at an expected retail price of 252,000 yen (2,800 dollars).

It will start exports to Taiwan and Europe in 2011, and forecasts total demand to reach 300,000 to 500,000 units by the mid-2010s as it expands into other markets, such as China.

"China is the largest market for electric bicycles, with estimated annual demand exceeding 20 million units," Yamaha said in a statement.

"A still more enormous market for electric motorcycles is expected to develop in China.

"The company is launching into this expanding global market with a view to gaining the highest share worldwide."

The motor scooter has a lightweight aluminium alloy frame and is powered by a 50V lithium-ion battery manufactured by .

"It emits no and can be stored away inside the house as it would leak no ," a Yamaha spokesman said.

The model represents a return to the electric market for Yamaha, which in 2002 became the first firm to mass produce an , the Passol.

It then launched two more advanced models in 2005 but stopped sales of all electric motorcycles in 2007 due to battery problems.

As long as it fits in the elevators.

I'm all in favor of electric vehicles. When electric motorcycles can cruise at 85 mph+ for over 125 miles I'm buying. I've been watching the development of electric cycles and I think the magic numbers are on the horizon. Performance wise, an electric Zero MX bike recently beat the gasoline bikes in a pro race. Swift, silent.

Fantastic! I have a 30km commute to work but could always charge it there...any idea if it will be marketed in North America? I'm also wondering how long the battery will last...

The military already has clean battery technology. Zero motorcycles is capitalizing on it right now and you can buy it. At 1/2 cent per mile to operate that's pretty damn clean and the designer claims you can eat the batteries. I'll have to take his word on that.

You know very well that they mean tail pipe emissions. Also, production,storage, and disposal are all present in conventional vehicles as well. Let's not pretend that this concept, and all similar electric transport systems, don't vastly reduce carbon emissions despite the trivial emissions in their creation and destruction. If we refused to take small sensible steps, and instead insisted and waited on grand leaps, we would never advance at all.

I think you need to be more realistic. This kind of technology is better than nothing afterall and i am certain we will never get a true zero carbon vehicle ever. Also bear in mind every green technology is not zero carbon either.

Give it time technology will find a way....one day.

Technology will find a way. The reason is that manufacturing and disposal themselves will begin to be zero or low carbon. The trick is to make the source of electricity low carbon. We could do it within the next twenty years.
Solar electricity from the southwest US (for the US) and from northern africa (for Europe) distributed by grids. Same thing for China. Current superconductor research right now is cruising along, would be the icing on the cake for a smart grid.

Next goals after that will be population control (which is kind of starting to level off in different parts of the world)
Sustainable agrigulture
Monitoring of environmental toxins.

Ok, easier said than done.

How are you going to convince the Pope and all those religious idiots that population control is not something we wish would happen by asking their followers to 'be responsible?'

Most of the problems in Africa are caused by the religious rules about 'doing it.' Same as Haiti, way over populated and ruled by the Pope.

China say 1 per, you gonna enforce that everywhere?

IT's really funny how some people try to
downplay electric vehicles, It is inevitable that
it WILL take over because it is a BETTER technology hands down.

You can stand on your head at a 45 degree angle
and it still would not change this very fact.

Electric is KING !!! and they produce ZERO emissions.

Electricity generation is an evolving technology, we are at the beginning stages, yet the progress made thus far is Astonishing to say the least !!!

SSSOOOO... Bring on the ELECTRIC REVOLUTION !

..Electric is KING !!! and they produce ZERO emissions.
The efficiency of electricity production from coal is 43 - 45%. The efficiency of battery cycle is 80 - 85%. The efficiency of electric motor is 85 - 90%. This gives total efficiency 30 - 35% of coal burning in electric motorcycle.

With compare to it the efficiency of two-stroke motors in motorcycles at 8:1 compression ratio is 25 to 27% - which is comparable to electric vehicle. In addition, the electric motorcycle is using battery of limited lifetime and the volume of wastes required for its production is two to three higher (their higher price indicates this). At the cities the electro-cycles can be competitive, but they're just helping to spread waste & environmental pollution outside of cities - not to decrease its total level.

You need to clarify yourself. Some of your post makes no grammatical sense.

Or we can not be hypocrites and not use coal to charge batteries. Let's use solar, wind, etc and see what the new numbers are. 25-27% efficiency? Are you including the energy to refine and transport the heavy gasoline?

My electricity comes from water and gravity. That's pretty efficient. Anyway, I see that you are still using electricity. How much pollution do YOU produce daily?

The higher price has more to do with R&D on a new technology, rather than indicating the waste associated with it. Companies do their best to reduce waste in order to have a larger profit margin(Duh).

The battery lifetime is improving fairly rapidly, as you would know if you bought battery operated power tools as often as I do.

I see nothing in your argument that has merit. Electric is far and away the better way to go.

I'm not so sure, until we produce it by burning of fossil fuels. After all - if it would, the economy based industry would use it already...

The most efficient use of everything at hand would be to encourage development of far more efficient gasoline and diesel engines. The infrastructure is in place -- no need to tear down the old and build all new systems. It would even be more efficient to develop engine retrofits for existing vehicles vs throwing away our old vehicles to replace them with all new manufacturing. I find it ridiculous that no one is taking this approach.

I would love to see a manufacturer offer a program where when it's time for a new car/bike, you bring in the old and they make it "new," more efficient and cleaner, for a fraction of the cost/waste associated with commissioning the manufacture of an all-new machine and the de-commissioning of an old one. They could even add some zippy bs visual elements to boost the owner's ego.

I build EV trike MC's from golf cart rears and moped/MC front ends/bodies. Just cut the GC off in front of the seat and weld the MC frame to it.

Change the batteries to 12v increasing the pack to 72vdc, replace the rear wheels with VW Rabbit or trailer 4 lug tires and you can have a nice 45mph, 60 mile range EV for under $1k that is very reliable.

Older GC chargers can by changing the rectifier to a bridge rectifier charge 72v pack correctly. With slight changes the CG contactor controllers can be used too.
