Electric bicycles, also known as e-bikes, are bicycles that have a motor that helps you go faster. Depending on where you live, there are different laws about e-bikes. Some places let you ride them anywhere regular bicycles are allowed, while other places have laws that say only people over the age of 18 can ride e-bikes on certain streets. In some places, it is illegal to ride e-bikes on sidewalks. In other places, you need to wear a helmet to ride an e-bike. It's important to check the rules in your area so you know what you can and can't do with your e-bike.
