There are several types of bicycles designed for different purposes. For instance, mountain bikes are built for rough terrains and off-road trails, featuring thick tires and sturdy frames. On the other hand, road bikes are lightweight and have thin tires, making them perfect for smooth pavements and long-distance rides. Another popular type is the hybrid bike, which combines features of both mountain and road bikes, making it versatile for various surfaces. Cruiser bikes are designed for comfort, often used for leisurely rides along the beach or in parks. Each type caters to specific riding styles and preferences.
