An electric bicycle (e-bike) is a bicycle with an integrated electric motor that can be used for propulsion. To introduce the e-bike, you could start by highlighting the benefits it offers such as increased speed and efficiency, making it easier to tackle hills and headwinds, and reduced physical strain compared to traditional bicycles. Additionally, you could mention that e-bikes are environmentally friendly as they produce zero emissions and require much less energy to operate than gasoline-powered vehicles. Furthermore, you could discuss the different types of e-bikes available, such as pedal-assist, throttle-controlled, and full-power e-bikes, to help the listener understand the range of options.
