Installation Steps:

  1. Mount the Bracket: Secure the handlebar mount to your handlebars or stem using the cable ties. Tighten them enough so the mount doesn't slip.
  2. Install the Sensor & Magnet:
    • Attach the magnet to a spoke on the front wheel.
    • Attach the sensor to the front fork leg (the metal part of the frame) using cable ties.
    • Crucial Alignment: The magnet must pass extremely close to the sensor (usually within 2–3mm) for it to register speed. Spin the wheel and adjust the sensor/magnet positions until they nearly touch but do not hit each other.
  3. Install the Head Unit: Slide the computer onto the mount until it clicks into place.
