5. Installation
Follow these steps to install your Tiakia phone holder:
- Attach the Handlebar Clamp Base: Choose the appropriate rubber pad size for your handlebar diameter (22.2mm, 25.4mm, 28.6mm, 31.8mm, or 35mm). Place the rubber pad inside the handlebar clamp base. Position the clamp on your handlebar and tighten the two screws using the provided hex key until it is secure. Ensure the base is firmly attached and does not rotate freely.
- Connect the Phone Holder to the Base: Align the spherical joint of the phone holder with the ball head on the handlebar clamp base. Push the phone holder onto the ball head until it clicks into place. Tighten the Phillips security nut clockwise to secure the phone holder at your desired angle.
- Adjust Bottom Claws (Optional): The bottom claws are adjustable in three positions to avoid blocking side buttons or ports on your phone. Adjust them as needed to fit your specific phone model.
