2. Setup and Installation
Follow these steps to properly install your NineLeaf SF31 Extra Remote Control on your bicycle handlebar:
- Prepare the Handlebar: Identify a suitable, clear section on your bicycle handlebar for mounting the remote control.
- Position the Silicone Ring: Place the provided silicone ring at the chosen position on the handlebar. This ring helps secure the remote and prevents slippage.
- Attach the Remote Control Holder: Place the remote control holder around the silicone ring. Ensure the contours on the holder align with the silicone ring for a snug fit.
- Secure with Screw: Use the provided screw to firmly fasten the remote control holder to the handlebar. Do not overtighten.
- Insert the Remote: Gently press the remote control down into the holder. Then, turn the remote control counter-clockwise until it clicks securely into place. This ensures the remote is locked into its mount.
The remote control is designed to easily clamp onto handlebars with a diameter between 0.78 and 0.94 inches (approximately 20-24 mm).
