eZee Kinetics Technology is based out of Shanghai, China. Its bikes are quite popular and are distributed in the United States, the UK, and the European Union, and a few other countries, not to mention in Shanghai, of course! www.ezeebike.com
In the US market, the importers are “Nycewheels” and “Electric Vehicles Northwest.”
The company offers eight models, and a kit to convert an already existing bike. These models include a cross-country bike, and a tricycle for those adults who need the extra security of three wheels.
They produce both E-bikes and EPACs. With an E-bike, the motor is activated by turning the throttle, and there is no need for pedaling. (The rider can still pedal, and adjust how much powered assistance is given by the throttle.). With the EPAC, the motor is only activated as the rider pedals
