Which Quad Lock setup do you need?

Quad Lock is sold as a system of separate parts rather than one all-in-one product. Which parts you need depends on where you want the phone and how you ride:

• Handlebar mounting:The mount on this page clamps to the handlebar and carries the twist-lock head. Quad Lock also sells fork stem, mirror-post and brake/clutch perch bases that share the same head, so the position can be changed later without new phone-side hardware.
• A compatible Quad Lock phone case or adapter:Required. The lock pattern lives on the back of a Quad Lock case; if there is no case for your phone model, the universal adhesive adapter is the alternative. Neither is included with the mount.
• Vibration dampener (optional):Sits between the mount and the phone to absorb high-frequency engine vibration. Recommended if your bike has noticeable handlebar vibration — see the vibration section below.

What you actually need to fit it

Quad Lock sells the motorcycle setup as separate parts. The listing on this page is the handlebar mount itself; the rest of the system is bought alongside it.

• Motorcycle handlebar mount (this product):Clamps to the handlebar and carries the twist-lock head. Included.
• Quad Lock phone case or universal adapter:Required. The lock pattern lives on the case; the universal adhesive adapter is the alternative if your phone model has no case available. Sold separately.
• Vibration dampener:Optional accessory that sits between the mount and the phone to absorb high-frequency engine vibration. Sold separately.
• Wireless charging head:Optional. Replaces the standard head to charge the phone while riding and needs a wired power feed from the bike. Sold separately.
• Weatherproof poncho / rain cover:Optional. The mount hardware is built for outdoor use, but the phone itself is only as weather-resistant as its own rating.

Why vibration management matters on a motorcycle

Handlebars transmit engine and road vibration straight into whatever is bolted to them. Modern smartphone cameras use optically stabilised lens elements that move on tiny suspensions, and phone makers — Apple among them — advise against attaching phones to motorcycles with high-amplitude, high-frequency vibration because of the risk to those camera systems.

Quad Lock's vibration dampener is designed to sit in the mounting path and absorb part of that high-frequency energy. It reduces what reaches the phone; it is not a guarantee that a phone or its camera will survive indefinitely, and Quad Lock does not present it as one. If you ride a bike with noticeable bar buzz and care about your camera, treat the dampener as part of the purchase rather than an upgrade.

This matters most on modern smartphones because nearly all of them — iPhone, Galaxy S and Pixel flagships among them — use optical image stabilisation, where the lens or sensor physically floats to counter hand shake. Those moving parts are exactly what sustained high-frequency vibration can stress over time. If your phone is a recent model with a stabilised camera, the dampener is the sensible precaution; if you mount an older phone or a cheap spare for navigation only, the risk calculation is yours to make.

Will it fit my motorcycle?

The handlebar mount is designed for common motorcycle handlebar sizes and clamps around the bar, so it fits most bikes with a standard round handlebar and some free clamp space. Before buying, check two things on your own bike:

• Free clamp space:You need a clear section of bar near the controls where the clamp can sit — switchgear, mirrors, lever perches and bar-end weights often take up the obvious spots, especially on nakeds with short bars.
• Handlebar diameter at the clamp point:Bar diameter varies between bikes and can taper along the bar. Measure where you intend to clamp and check it against Quad Lock's own fitment guidance on their site rather than assuming — Quad Lock publishes the supported sizes and any spacer options for each mount base.
• If the bar does not work:Quad Lock sells fork stem, mirror-post and brake/clutch perch bases that share the same twist-lock head, so an awkward handlebar does not rule the system out.

Installation and fitment

• Mounting location:The handlebar version clamps around the bar. Quad Lock also sells fork stem, mirror-post and brake/clutch perch bases that share the same head, so the position can be moved without changing phone hardware.
• Orientation:The twist-lock head accepts the phone in portrait or landscape, so the map view can be set to suit the cockpit.
• Handlebar compatibility:The mount is designed for common motorcycle handlebar diameters; check Quad Lock's own fitment guidance against your bar before ordering rather than assuming — bar shape and available clamp space vary a lot between bikes.
• Attachment and removal:Place the phone onto the head and rotate to lock; a secondary lever or latch keeps it from rotating free. Removal is the same motion in reverse, one-handed, gloves on.

Who should buy it

Frequently asked questions

Do I need a Quad Lock case to use the motorcycle mount?

Yes. The twist-lock pattern lives on the back of a Quad Lock case, so the mount will not hold a bare phone on its own. If Quad Lock does not make a case for your phone model, the universal adhesive adapter sticks to your existing case and provides the same lock pattern.

Will the Quad Lock motorcycle mount fit my handlebars?

The handlebar version is designed for common motorcycle handlebar sizes and clamps around the bar, so it suits most bikes with a round bar and free clamp space. Bar diameter and available space vary a lot between bikes, so measure where you plan to clamp and confirm against Quad Lock's published fitment guidance before ordering. Fork stem, mirror-post and perch bases exist if the handlebar does not work.

Is the vibration dampener really necessary?

It is an optional accessory, not a requirement. Phone makers including Apple warn that sustained high-frequency vibration — the kind handlebars transmit — can stress the moving parts in optically stabilised cameras. If your bike has noticeable bar buzz and your phone has a stabilised camera, the dampener is the sensible add-on; it reduces vibration reaching the phone but is not a guarantee against damage.

Can I charge my phone while it is on the mount?

Yes, with Quad Lock's separate wireless charging head, which replaces the standard head and needs a wired power feed from the bike. It is not included with the handlebar mount.

Should I use a Quad Lock mount or a dedicated motorcycle GPS?

If you already navigate by phone and ride commutes, day trips and tours with regular stops, the mount plus your phone is the simpler and cheaper setup. A dedicated GPS makes more sense for very long days, poor weather or bright sun, where a purpose-built screen and battery outperform a phone.
