BioSync™technology, comprised of our advanced MultiSensor and proprietary smart controller, reads the power output of a rider during a natural pedal motion. It then matches that output to give you the most efficient and comfortable ride on your Electric Bike. During the natural pedal motion of a bicycle rider, there are apex points of power. A natural pedal motion consists of several phases, including preparatory phase, power phase, follow through phase, and recovery phase. Your pedal power varies through its rotation, so why wouldn’t a technology that is meant to enhance your riding experience do the same. When biosync was developed, EVantage worked to make sure the motor system varies the power output to match that natural power rotation. The result is a riding experience that is smooth and doesn’t feel abnormal. BioSync™ eliminates the uneven, jerky ride that plagues most low-tech Electric Bike power sensors. By regulating the wattage output, EVantage bicycles save power while you save charging time.
