In 1903, Harley-Davidson produced a motorized two-wheeler for the first time, the so-called Serial Number One. In reference to this vehicle, the Harley makers are now naming a new company division: from 2021, Harley will be offering genuine e-bikes under the Serial1 label. From the look of the e-bike, the cult motorcycle manufacturer seems to be serious about its commitment to the e-bike sector. Of course, the familiar belt drive will not be missing.
