A mountain bike is designed for riding on rough and bumpy terrain, like mountains, hills, and trails. It has big tires, deep treads that help it grip the ground, and a sturdy frame that can handle bumps and jumps.
Mountain bikes also have special gears and brakes that make it easier to ride up and down steep hills. People ride mountain bikes for fun, exercise, and to explore the outdoors.
Wear protective gear like a helmet and pads when riding a mountain bike, and always be aware of your surroundings and ride safely!
