I picked up a copy of Cycle World's 2011 Buyer's Guide at the news stand this week. The magazine provides a short description of the 440 motorcycles on sale in the US. Electric motorcycles are represented and described in the magazine and consist of the following models:
Brammo Empulse ($9995 to $13,995)
Brammo Enertia Plus ($8995)
Brammo Enertia ($7995)
Zero S/DS (price not available)
Zero MX/MX Street (price not available)
In addition to these well known models two other EVs (sort of) are listed in the magazine as being offered for sale in the US.
Hyosung ST-E3 EVA (price not available): This is a 50cc-size scooter with a 1.5kW brushless DC electric motor powered by a battery pack. It claims a range of 62 miles at 22 mph and has a claimed top speed of 40 mph. Wheels are 12 inch, brakes are drum at both ends and it comes in a wide range of colors, from plain white to hot pink.
Piaggio is selling their three wheeled MP3 Hybrid for $8499. It has a 125cc IC engine supplemented by an electric motor.
And that seems to be about it for production electric motorcycles this year in the US.
