What are the key differences between an endurance bike and a road bike, and how do these differences impact performance and comfort for long-distance cycling?

Endurance bikes are designed for comfort over long distances, with a more relaxed riding position, wider tires, and often more shock absorption. Road bikes, on the other hand, are built for speed and efficiency, with a more aggressive riding position and narrower tires. These differences impact performance and comfort by providing a smoother ride on rough roads and reducing fatigue on longer rides with an endurance bike, while a road bike offers better speed and agility for shorter, faster rides.
