Mountain bikes are specially designed bicycles built for off-road cycling. They feature sturdy frames, wide tires with deep treads, and strong brakes to handle rough terrains like dirt trails, rocky paths, and steep hills. These bikes often come with suspension systems that absorb shocks, making rides smoother and more comfortable on bumpy surfaces. Riders can choose from various types of mountain bikes, including hardtail models with front suspension only and full-suspension bikes that have both front and rear suspension. Whether you're a beginner or an experienced cyclist, mountain biking offers an exciting way to explore nature and enjoy outdoor adventures.
