A gravel bike is a special kind of bicycle that lets you ride on different types of roads and trails. It's like a mix between a road bike and a mountain bike.
Think of it like a car that can drive on both highways and dirt roads. The gravel bike has some features that make it good for riding on rough or unpaved roads. The tires are wider and can handle rough terrain better than regular road bike tires. They also have a more comfortable saddle, or seat, than a mountain bike, which can help on longer rides.
The handlebars on a gravel bike are often wider than a road bike, which gives you more control over the bike on rough terrain. They also have some features that make them good for carrying gear, like panniers or saddle bags, if you're going on a longer ride and need to bring things like food, water, and extra clothes.
Overall, a gravel bike is a versatile and fun bike that can take you on all kinds of adventures!
