E-bikes are bicycles with a battery-powered “assist” that comes via pedaling and, in some cases, a throttle. When you push the pedals on a pedal-assist e-bike, a small motor engages and gives you a boost, so you can zip up hills and cruise over tough terrain without gassing yourself. 

Electric bike systems offer a number of modes to choose from, allowing you to balance the amount of power supplied through the pedals with range and battery life.
