Bike odometers are small computers that measure your riding status. The computer takes information from sensors located on your bike wheel and calculates your speed, distance or cadence. These computers often provide other information such as your riding time, your heart rate or the altitude. Installing a bike computer is very simple even if you are not a bike mechanic, but you must set your computer properly to obtain an accurate speed from the sensors.
Attach the computer mount by a rubber ring to your handlebar or stem in a location that is easy for you to see.
Run the wire(for wired cycle computer) and attach the sensor to the fork by cable ties.
Clip the included magnet to the spokes of your front tire in a place where it will pass by the sensor each time your wheel rotates.
Make sure the distance between sensor and magnet is about 3 MM.
Secure the bike odometer to the computer mount and start programming the computer.
You see, it is quite simple!
