A phone on a motorcycle is a navigation aid, a camera and sometimes a communication device. It is also a heavy object attached to a vibrating machine. A weak clamp, a worn rubber or a cheap arm can let the phone go at speed.

What it does

The mount holds the phone where the rider can see it without looking down for long. It also isolates the device from vibration that can damage a camera or a screen.

A good mount has a positive lock, a secondary retention feature and a way to charge the phone. It should not block the instruments, the ignition or the controls.

How it mounts

Clamps grip the phone's edges or use a case-specific cradle. A spring-loaded clamp must have enough travel to hold the phone firmly without pressing the buttons. A screw clamp is more secure but slower to use.

Vibration reaches the phone through the bar and the mount. Some mounts use rubber isolators. A phone's camera stabilisation can be damaged by high-frequency vibration, especially on a single-cylinder bike.

Materials and types

  • Handlebar clamp mount. Clamps to the bar. Simple and adjustable.
  • Fork stem mount. Fits into the steering stem. Central and out of the way.
  • Case-specific mount. A cradle for a particular phone or case. Secure but less universal.
  • Magnetic mount. Quick to use, but only as good as the magnet and the surface.
  • Wireless charging mount. Charges without a cable. Needs a switched power supply.

Wear and failure signs

  • A clamp that has loosened or cracked.
  • Rubber pads that have hardened or fallen off.
  • A mount arm that vibrates loose.
  • A charging port that no longer connects in the rain.
  • A phone that overheats in direct sun.
  • A cable that rubs on the bar or the tank.

Choosing a part

  • Choose a mount with a positive lock and a secondary retention feature.
  • Check that the mount fits the bar diameter or stem.
  • For a camera phone, consider a vibration-damped mount.
  • Check that the phone does not block the instruments or the ignition.
  • Use a waterproof case or a waterproof phone if you ride in rain.

Fit and compatibility

  • Clean the bar or stem before fitting.
  • Tighten the clamp firmly and check it after the first ride.
  • Route the charging cable away from the steering and hot parts.
  • Check that the phone does not hit the tank or screen at full lock.
  • Test the mount on a rough road before trusting it.

Care and adjustment

  • Check the clamp and rubbers at every service.
  • Remove the phone in strong sun to avoid overheating.
  • Keep the charging port clean and dry.
  • Replace worn rubber pads.
  • Do not leave the phone on the mount when the bike is parked in public.

Safety and limits

A phone that falls from a mount can distract or hit another road user. Secure it properly.

Do not operate the phone while riding.

A mount that blocks the instruments or the view is a safety problem. Reposition it.

Questions

Can vibration damage my phone camera?

Yes. Some camera stabilisation systems are sensitive to high-frequency vibration. A damped mount reduces the risk.

Are magnetic mounts safe?

They can be, if the magnet is strong and the phone has a metal plate. A positive mechanical clamp is more secure.

Can I charge my phone from the bike?

Yes with a USB charger wired through a switched, fused circuit. Check the charger's output and weather sealing.

Will a phone mount block my view?

It can if it sits high or in the wrong place. Check the position with the bike upright and the rider seated.
