Heart Rate Zone Calculations

Zone % of Perceived Exertion
Maximum
Heart Rate
1 50–60% Relaxed, easy pace,
rhythmic breathing
2 60–70% Comfortable pace,
slightly deeper
breathing, conversation
possible
3 70–80% Moderate pace, more
difficult to hold
conversation
4 80–90% Fast pace and a bit
uncomfortable, breathing
forceful
5 90–100% Sprinting pace,
unsustainable for long
period of time, labored
breathing
Wheel Size and Circumference
Your speed sensor automatically detects your wheel size. If
necessary, you can manually enter your wheel circumference in
the speed sensor settings.
The tire size is marked on both sides of the tire. This is not a
comprehensive list. You can also measure the circumference of
your wheel or use one of the calculators available on the
internet.
