The E-Vivacity is powered by a 4kW electric engine, which gets juice from lithium-ion batteries. Unlike some of the latest electric scooters, the motor is not mounted directly to the rear wheel hub. Instead, the power is transmitted to the rear wheel via a belt drive. The lithium batteries can be fully recharged in 5 hours. The scooter uses the kinetic energy during the deceleration phase to charge the batteries. The E-Vivacity goes into production in January 2011. Prices should fall in the range between 3000 and 3500 euro, but this would not be official yet.
