Correct saddle height is very important for a cyclist. If you intend to ride your bicycle a lot, this app can guide you through the process of determining the best saddle height for you.

If your knees hurt while you ride, check that saddle! Is it too low; or too high? If your knees hurt in front, you\’ve got the seat too low; and if the back of the knees hurt, it’s too high. Another cause of knee pain is pedaling too hard a gear for your fitness level; but that’s another story.

A professional bike fit is a good idea, too; and that’s the route I took. It was expensive; but well worth it.
