Bicycling is a healthy activity, but pedaling at a low cadence on an ill-fitted bike can lead to knee injury. Cadence refers to the revolutions of the pedal crank per minute: the rate at which you are turning the pedals. Higher cadence more evenly applies power throughout the rotation.
If you use clip-less pedals with bike shoes, cadence is especially important as you are both pushing and pulling on the pedals. After I developed some tendonitis, a physical therapist and others recommended a cadence of at least 88 rpm with clip-less pedals, a level that at first seemed unnaturally high. A cadence gauge on my bike computer trained me to make this the new normal.
