The invention provides a measurement device and method for measuring acyclist's power output, in response to anexternal force provided by said cyclist applied to a bicycle, comprising aforce sensor (13), characterised in that said force sensoris embedded in a bicycle cleat (11) bolted to the shoe (10). The inventionfurther provides an accelerometer (14) for measuring acyclist's power output. The inventive device and method provides a number ofadvantages over prior art solutions. The device ofthe invention means that the installation does not need any part of thebicycle to be replaced. The present invention does notrestrict the type of components that may be used on the bicycle. Because thesensors are embedded in the cleat it is very simple tomove the system to another bicycle. The invention also allows for detailedanalysis of pedalling style, leading to improvements inefficiency.
