What is a belt drive on an electric bike?

A belt drive on an electric bike is a type of drivetrain that uses a belt instead of a traditional chain to transfer power from the motor to the rear wheel. Belt drives are known for their smooth and quiet operation. They also require less maintenance compared to chain drives as they don't require regular lubrication and are less prone to rust and dirt buildup. Additionally, belt drives are lighter in weight and can be more durable than chains. However, belt drives can be more expensive to replace if they break and may not be compatible with certain bike frames or gear configurations.
