The BKM3 Bike Speed or Cadence Monitor mounts easily onto a bike frame. Measurement of bike speed

or bike cadence can be selected by with the small micro-switch at the base of the unit. To measure speed,

position the monitor on the back of the rear triangle and position the bike magnet pickup on the spoke.

To measure cadence, position the monitor on the bottom of the rear triangle and position the bike magnet

pickup on the crank arm.

• Attach all pieces securely. Any sliding motion will affect accuracy.

• 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. Misalignment will affect accuracy.

The BKM3 Bike Speed or 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 BKM3 Bike Speed or 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

speed or cadence monitor. You can be in proximity to other ANT-enabled devices.

• After the BKM3 Bike Speed or Cadence Monitor pairs with the sports monitoring watch, the bike

icon appears on the watch’s LCD display.
