After receiving the bike computer
1.Attach the computer sensor to the fork opposite your brakes on the front wheel mount.
You can attach the sensor at any point along the fork, so choose a location that will be easy for you to access.
The distance between the sensor and the magnet must not exceed 1.5CM.
2.Attach the computer mount to your handlebars in a location that is easy for you to see.
The computer's display will go in this mount, so it must be in a location that is easily visible.
The distance between the sensor and the computer can not exceed 60CM.
3.Enter the diameter of your front bicycle tire into the computer.
This information is usually printed on the tire itself or will appear in your bicycle's user manual.
Your computer must know the tire diameter in order to calculate your speed accurately.
4.Turn the tire to ensure the computer sensor is detecting the magnet as it goes by.
Your computer display will show a nonzero speed value if the sensor is working correctly.
