Pedal assist is a feature found in many electric bicycles, or e-bikes, that helps riders by providing additional power while pedaling. This system uses sensors to detect how hard the rider is pedaling and then delivers a boost of electric power to make cycling easier, especially on hills or during long rides. Riders can usually adjust the level of assistance, allowing for a customizable experience based on their fitness level and the terrain. This makes pedal assist a popular choice for commuters and recreational cyclists who want to enjoy the benefits of cycling without excessive strain.
