BEST IBOLT MOUNTAIN BIKE PHONE AND ACTION CAMERA MOUNTS

Why Mountain Bikers Need Purpose-Built Phone and Camera Mounts

Mountain bikers push their gear harder than almost any other rider. Rock gardens, root sections, drops, and high-speed descents throw constant vibration and sudden shock into anything bolted to the bars or seat post. A phone or action camera mount that works fine on a road bike or commuter setup often fails on singletrack, either loosening over time or bouncing the screen out of a usable viewing angle.

Riders lean on their phones for more than music. Strava, trail maps, heart rate data, and ride tracking all live on the screen, and a growing number of riders run an action camera at the same time to capture the descent. That means the mount has to do two jobs: hold a phone securely enough to trust on a rock garden, and give you a solid, repeatable base for a GoPro or similar action camera.

Below are the iBOLT mounts built for that job, along with what to check on your own bike before you order.

iBOLT Moto-Vise Bizmount Clamp: Heavy Duty Smartphone Claw Mount

This is a claw-style clamp that attaches to any round handlebar section up to 2 inches in diameter, no tools required for quick mounting or removal. The included Bizmount adapter uses the industry-standard 1-inch / 25mm / B-size ball, so it is compatible with other iBOLT holders and most third-party accessories built around that same ball size.

Once the phone is mounted at the stem, riders get quick glances at Strava, trail maps, or ride metrics without pulling the phone out of a pocket or pack. It also puts the phone within reach to start, stop, or check an action camera that is recording the ride from a separate mount, which is useful if you are running a GoPro on the seat post or helmet and want to confirm it is actually filming before you drop in.

Before ordering, measure the section of handlebar where you plan to clamp it. Bar-mounted accessories, lights, or dropper post remotes can eat up usable clamping space quickly on a mountain bike cockpit.

iBOLT Moto-Vise Bizmount Metal Handlebar Phone Mount

This is the bolt-down version of the clamp above, built for riders who want a permanent, tool-tightened base rather than a quick-release claw. It fits handlebars up to 1.2 inches and is tightened with the included hex key, which is worth doing properly since a loose bolt-on mount is one of the more common causes of a dropped phone on rough trail.

Like the claw mount, it uses the same industry-standard 1-inch / 25mm / B-size ball, so the same Moto-Vise holder and other B-size accessories will interchange with it. If you already run a claw mount on one bike and want a fixed mount on a second bike, the ball compatibility means you can move a single phone holder between them.

Choose this over the claw mount if you rarely need to remove the base itself and want the most rigid connection possible for hard drops and steep, rocky descents.

iBOLT 17mm Clamp Mount for Handlebars, Poles, and Posts

This clamp is built around a 17mm ball and pairs directly with any 1/4-20 camera adapter, which covers most action camera and GoPro-style mounting accessories. It clamps onto handlebars, seat posts, or other round tubing, which opens up a lot of camera angle options beyond the standard bar-mounted forward shot.

A common setup among riders capturing trail footage is one camera forward-facing on the bars and a second mounted on the seat post pointing back, giving you both a front and rear view of the same descent to cut together afterward. Since the mount uses an industry-standard ball and clamp design, it also works with many Garmin GPS units and other devices built around the same ball pattern.

Before buying, confirm your action camera's mount uses a standard 1/4-20 threaded adapter (most GoPro-style mounts include one or accept a simple adapter) so it seats correctly on the 17mm ball.

Completing the Setup: Holders and Adapters

If you already own one of the mounts above, these two pieces let you expand or adapt the kit rather than buying a whole new base.

iBOLT Moto-Vise XL Holder with 25mm / 1-Inch Ball
This phone holder ships with the Bizmount clamp kit, but it is also sold separately for riders who already have a compatible 1-inch / 25mm / B-size base and just need the holder itself. It uses a spring-loaded grip designed to hold the phone securely through repeated impacts rather than just steady-state vibration, which matters more on singletrack than on pavement.

1-Inch Ball to 1/4-20 Camera Screw Mount Adapter
This is a simple, small adapter for riders who need to attach an action camera or GoPro to any 1-inch iBOLT Bizmount ball or other industry-standard 1-inch (25mm) ball mount. It allows 360-degree rotation, so you can level the shot regardless of how the mount itself is oriented on the bar or post. It is worth keeping a couple of these in a pack or saddle bag since they are inexpensive to lose and easy to need mid-ride.

What to Verify Before You Buy

• Handlebar or post diameter: Clamp mounts have a stated diameter range. Measure your bar or seat post where you actually intend to mount it, not just the widest section near the stem.
• Ball size compatibility: iBOLT's phone mounts use a 1-inch / 25mm / B-size ball, while the handlebar clamp for cameras and GPS units uses a 17mm ball. Confirm which system your existing holders or GPS unit use before assuming they will interchange.
• Action camera adapter type: Most GoPro-style cameras use a proprietary two-prong mount, not a direct 1/4-20 thread. You will likely need the camera manufacturer's 1/4-20 adapter (many ship with one) to pair with iBOLT's ball adapters.
• Removal frequency: If you swap the mount between bikes or remove it after every ride, the claw clamp is the faster option. If it stays on one bike permanently, the bolt-down metal mount is more rigid over the long term.
• Available cockpit space: Dropper remotes, lights, and lock-on grips all compete for handlebar real estate. Check what is already clamped near your intended mounting point before ordering.

FAQ

Will these mounts fit my mountain bike's handlebars?
The claw clamp fits round bar sections up to 2 inches, and the metal bolt-down mount fits up to 1.2 inches. Measure the specific section of bar you plan to use, since cockpit shape varies by bike.

Can I mount a GoPro or other action camera directly to these mounts?
The 17mm clamp mount and the 1-inch ball adapter both work with standard 1/4-20 camera threads. Most action cameras need their own 1/4-20 adapter first, since the camera mount itself is usually a proprietary two-prong design.

Are these mounts rated for rough trail vibration and impacts?
They are built with a spring-loaded holder and metal or reinforced clamp hardware intended for repeated shock, which is different from mounts designed only for steady highway vibration. That said, always seat the phone or camera fully and check tightness periodically, especially after a hard crash or drop.

Can I run a phone mount and an action camera mount at the same time?
Yes. A common setup pairs a bar-mounted phone holder for navigation and ride data with a seat post or second bar mount running the action camera, giving you a forward and rear view option.

Do these mounts also work on road bikes or motorcycles?
The clamp and handlebar mounts are built around standard round tubing and the same ball sizes used across iBOLT's motorcycle and cycling lines, so they generally fit other bike types with compatible bar diameters. Confirm your specific bar or post measurement against the listed range before buying.

What is the difference between the claw clamp and the metal bolt-down mount?
The claw clamp is designed for quick attachment and removal without tools, useful if you move the mount between bikes. The metal mount bolts down with a hex key for a more permanent, rigid connection, which suits riders who leave it installed long term.
