The Walfront YA100 A comes with two mounting options:

1. Standard Speedometer Bracket: Attach this bracket to your bicycle's handlebar or stem using the provided cable ties. Ensure it is securely fastened and positioned for easy viewing.
2. Extended Handlebar Bracket: For a more forward-extended position, use the extended handlebar bracket. Secure it to your handlebar with the provided cable ties, ensuring stability.

Once the bracket is installed, slide the bike computer onto the bracket until it clicks into place. To remove, press the release tab and slide the computer off.

3.3 Installing the Speed/Cadence Sensor and Wheel Magnet

The sensor should be mounted on the bicycle's fork or chainstay, close to the wheel spoke. The wheel magnet should be attached to a spoke on the front wheel. Ensure the magnet passes within 3mm of the sensor when the wheel rotates. Adjust the sensor and magnet positions as needed for optimal detection.
