The US-based Brammo Inc. has recently introduced Enertia, an electric motorcycle that offers users an ecological means of transport. Unlike most 'green' vehicles, Enertia's performance promises to match that of most motorbikes, while keeping clean the surrounding air.

The Brammo Enertia was announced several months ago, but only recently was it made available for sale. It is a motorcycle powered solely by electricity; therefore, the amount of carbon dioxide emitted is reduced by 92% in comparison to a standard car. However, the vehicle's 'refuel' time – or to be more accurate, its recharge time – is approximately 3 hours, significantly longer than most vehicles'. Each such recharge is good for a 35 to 45 miles drive. The Enertia features horsepower of 13.7, produced by its High Output Permanent Magnet DC motor. The supplied battery is based on Lithium Ion Phosphate (76.7V voltage) and its pack current is of 240A. Unlike most sport motorbikes, the Enertia has no clutch since it is equipped with single speed direct chain drive.
