The PS900 Bike has two ways of monitoring your heart rate:
...By using a chest strap that transmits your heart rate to the bike
via radio...
...or by using the metal contact heart rate pads on the handlebars.
Although your bike functions fine without using the heart rate
monitoring feature, this kind of monitoring gives you valuable
feedback on your effort level. Chest strap monitoring also allows
you to use Heart Rate Control, which is the most advanced
exercise control system available.
