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

Endurance bikes are designed for comfort and stability over long distances, with a more relaxed riding position and wider tires for a smoother ride. Race bikes, on the other hand, are built for speed and agility, with a more aggressive riding position and narrower tires for better aerodynamics. These differences impact performance by affecting speed and handling, with endurance bikes being more comfortable for long rides but sacrificing some speed, while race bikes are faster but less comfortable for extended periods of time.
