Learn how to install the Fenix ALD-10 bike mount on your handlebar, attach a compatible Fenix flashlight, and use the GoPro adapter for more mounting options.

Quick Answer

Install the Fenix ALD-10 bike mount by securing the base to your handlebar, then use the quick-release lever to attach your flashlight. For GoPro compatibility, swap the flashlight cradle for the GoPro adapter plate.

Why the ALD-10 Stands Out

The Fenix ALD-10 is a quick-release mount that lets you attach a compatible Fenix flashlight to your bike's handlebar. Its lever-based design means you can remove the light in seconds when you park your bike, reducing the risk of theft and making it easy to carry the light with you.

The included GoPro adapter expands your options: you can mount the flashlight on a GoPro-compatible helmet mount, chest mount, or other accessories. This versatility makes the ALD-10 a practical choice for commuters and off-road riders who already use GoPro mounts.

Compatibility Check

Before buying, verify that your flashlight's body diameter fits the ALD-10 clamp. The mount is designed for specific Fenix flashlight models, so check the product specifications or the Fenix website for a list of compatible lights. Using an incompatible light may result in a loose fit or damage to the mount.

Also confirm your handlebar diameter. The ALD-10 typically fits standard handlebars, but if you have an oversized or aerodynamic bar, you may need a different mount.

Step-by-Step Setup

Gather your tools and parts: You'll need the ALD-10 mount, a compatible Fenix flashlight, a 4mm hex wrench (usually included), and your bike. If you plan to use the GoPro adapter, have that piece ready as well. Check that the mount is the correct size for your handlebar and flashlight before starting.
Position the mount on the handlebar: Loosen the clamp screw with the hex wrench, slide the mount onto the handlebar in your desired position, and angle it so the flashlight will point forward. Tighten the screw firmly, but avoid over-tightening which could crack the mount or damage the bar. Ensure the mount is level and the light will not interfere with brake or shift cables.
Attach the flashlight: Open the quick-release lever, place your flashlight into the cradle, and close the lever until it clicks. Adjust the angle of the light by rotating it in the cradle before fully tightening the lever. The light should be secure and not wobble; if it does, reopen the lever and adjust the cradle size if possible.
Install the GoPro adapter (optional): If you want to use a GoPro mount, remove the flashlight cradle from the mount base and attach the GoPro adapter plate instead. Then, slide the adapter into any standard GoPro mount (helmet, chest, or handlebar) and secure it. Make sure the adapter is locked in place and the flashlight is oriented correctly before riding.
Test and adjust: Before heading out, give the flashlight a gentle tug to confirm it's secure. Turn on the light and check the beam pattern. Adjust the angle if needed to avoid blinding oncoming traffic. Re-check the tightness after the first ride, as vibrations can loosen the mount.
