GHB Bike Computer Odometers Bicycle Speedometer Wireless Waterproof Multi Function With Backlight

Fast Installation Guide

Mount the bike computer bracket to the bike handle bar. Then mount the sensor to the front wheel fork (front wheel will ensure accurate data), and finally attach the magnet to a spoke in the front wheel (please make sure the magnet is pretty close to the sensor, less than 3mm)

Warm Tips of Installation (VERY IMPORTANT!!!)

1. This bike computer has the function of Setting tyre circumference (0mm~9999mm) , so before using, just set your bike wheel size in the bike computer.

2. Once the magnet is installed, attach the sensor to the fork. Before securing the sensor to the front wheel fork by using the plastic tie-wraps, please first test the computer and see if the readings are ok, and make any necessary adjustments to the sensor or magnet position.


– Backlight: The display is easy to read especially with the back light which will make it visible at night.

– Auto On/ Auto Off: The bike computer shuts off when the bike is stationary due to a built-in steel ball which will automatically awake from sleep mode to save the life of the battery.
