What's the difference between speed & cadence?
Speed and cadence are both commonly measured in bicycling. Speed describes how fast the bike is moving, while cadence describes how fast the bike is being pedaled.
Cadence cannot be directly related to speed without taking other things into consideration, such as the gear that's being used and whether or not the rider is coasting.
All GPS devices can measure speed, but cadence is only available on models that are equipped with a cadence sensor (e.g., Edge 305).
