What are the differences between a bike computer and a watch for tracking cycling activities?

A bike computer is a dedicated device that attaches to your bike and provides detailed data on your cycling activities, such as speed, distance, and route mapping. A watch, on the other hand, is worn on the wrist and can also track cycling activities but may have fewer features and a smaller display. Both devices can track your cycling performance, but a bike computer typically offers more advanced metrics and customization options compared to a watch.
