This mount package includes Arkon’s Mega Grip one-touch push-button phone holder, a clamp post mount, and a bungee secure strap. The bungee strap, relative to other bike mounts on the market, is unique and wraps around the phone to provide added stability and protection while riding. The cell phone holder’s unique side-grip technology provides a strong grip that’s easy to use. Just set your iPhone 12 or Android smartphone in the holder and close the arms to lock in place. A push of the phone holder’s side button releases the phone. The clamp post mount fits on handlebars and other posts measuring 12 to 40mm in diameter and is easy to install with a turn of the mount’s knob. Use SM431 on a treadmill, elliptical, or other exercise equipment. The mount’s swivel ball head rotates 360°, providing the ultimate flexibility in viewing the smartphone from any angle.
