Keep Your Phone Secure While Cycling
Follow maps and view ride information more conveniently with the Joyroom JR-ZS288 Bicycle Phone Holder. Its four-corner mechanical clamp supports compatible 4.7–7-inch smartphones and includes a rear locking control for added stability.
One-Click Automatic Clamping
Open the holder, position your phone and press it against the centre release button to close the four supporting arms automatically. Engage the rear mechanical lock before riding to help prevent the clamp from opening accidentally.
Four-Corner Phone Protection
The holder supports the phone from four corners rather than gripping only its sides. Thickened silicone contact points improve grip, help reduce vibration and protect compatible devices from direct contact with the rigid PC and ABS frame.
360-Degree Adjustable Viewing
A ball-joint connection allows the phone to rotate between portrait and landscape orientations. Adjust the screen to a comfortable angle for navigation while keeping your attention on the road.
Designed Specifically For Bicycles
The supplied information states that this model is intended only for bicycles. Its adjustable handlebar clamp installs using screws and is designed for compatible round handlebars.

Important Safety Information
Ensure the holder does not interfere with brake cables, gear controls, lights or safe steering. Tighten the handlebar clamp and ball-joint nut before every ride.
A phone’s screen size alone does not guarantee compatibility. Case thickness, camera position, phone width and button placement may affect the fit. Remove unusually thick or oversized cases if the device cannot be secured correctly.
The silicone padding may reduce vibration, but the product should not be described as completely shockproof. Avoid extreme trails, jumps or impacts unless the mount has been tested for those conditions.
