Heart Rate Monitor

Whether you ride for health and fitness or for the excitement of pushing yourself farther, a heart rate monitor (HRM) is a great accessory. A wristwatch with a chest strap and electrodes uses radio waves to transmit your heart's electrical activity in beats per minute.

If you're looking to burn fat or ride faster, longer or harder, a HRM will help you maintain an optimum rate for what you're looking to accomplish. It will keep you from both underachieving or overexerting.
