A cadence sensor is a device that measures the frequency of pedalling. This sensor helps cyclists optimize pedaling efficiency and maintain consistent power output during a ride. The cadence sensor can be connected to the bike computer via cable or wirelessly (e.g. via ANT+, Bluetooth, etc.). Modern sensors are often combined with a speed sensor and can be easily installed on the cranks or frame of the bike. Regular cadence monitoring can help prevent muscle overload and improve overall pedalling efficiency.
