Polar speed sensor

The Polar Speed Sensor is a wireless sensor measuring cycling speed and distance via a magnet rotating on the front wheel.

There are a range of factors that can affect your cycling speed. Obviously fitness is one of them, however, weather conditions and the varying gradients of the road play a huge part too.

The Polar speed sensor W.I.N.D will measure your speed and distance as you ride. It will send the data to your bike computer via W.I.N.D transmission that will show you the data during your exercise.
