The BKM2 Bike Cadence Monitor mounts easily
onto the bottom of the rear triangle of a bike
frame. Position the magnet on the inside of
one of the crank arms.
• Attach both pieces securely. Any
sliding motion will affect accuracy.
• As the pedal rotates, the bike magnet
should sweep within 3 mm of the
front of the monitor housing on a
path perpendicular to the top edge of
the monitor. Any misalignment will
affect accuracy.

The BKM2 Bike Cadence Monitor must “pair” with an ANT-enabled sports monitoring watch in order to
display performance data to the user. To pair your monitor:
• Bring the BKM2 Bike Cadence Monitor within 10-30 inches (25-75 cm) of the sports monitoring
watch.
• Ensure that you are standing at least 72 inches (183 cm) away from any other ANT-enabled bike
cadence monitor. You can be in proximity to other ANT-enabled devices.
• After the BKM2 Bike Cadence Monitor pairs with the sports monitoring watch, the bike icon appears
on the watch’s LCD display.
