Review – Bar Fly 4 Max GoPro Mount Bundle

by Brian Mullin on December 10, 2015

Bar Fly 4 Max mount for GPS bike computers, with one bolt clamp design, bottom accessory mounts, user-friendly Derlin plastic construction and a lifetime guarantee!

The Bar Fly 4 Max is a superb mount for the GPS bike computers, offering an easy to use one bolt clamp, compatibility with 31.8 and 35.0 handlebars, and lowered positioning to be inline with the stem. It utilizes Derlin plastic construction, which is friendly to handlebars and GPS computer mounting wings, such as on the Garmin Edge series. The bottom of the 4 Max allows attachment of three different accessory mounts, including a universal GoPro finned style mount, a light mount, and a Di2/EPS junction box.

It’s designed to accommodate a broad range of computers, including the new large format Garmin Edge 1000. The 4 Max is compatible with Garmin, Joule, Cateye, Mio and Magellan computers, and can fit the Garmin 310/910/920XT watches with the QR mount.

Bar Fly has an excellent Lifetime warranty, with a no question asked replacement policy. They sell the 4 Max mount with the three accessory mounts for $39.95.

Impressions

The simple one bolt design of the clamp makes it easy to take on and off, so you can easily swap it between bikes. The mount is made of Delrin plastic, so the clamp section is safe for carbon bars, and of utmost importance, the primary computer interface is friendly to the plastic wings on the back of GPS computers. Even with the one bolt setup and full plastic body, the mount offered a secure and stable platform for the computers. It utilizes a lower mounting position, so it drops the computer down inline with the stem, for improved viewing and visibility.

I tested the 4 Max on various bikes, handlebars, and stems, and it’s easy to install the one bolt clamp, just undo the bolt, bend open the clamp, and pop it over the bars and align, and torque it down. When using with 31.8mm bars, you’ll need to use the rubber shim for proper tightness. The computer interface gave a nice crisp click into its lock, and I wasn’t able to discern any damage to the computer wings during repeated use. My Edge 1000 that I used for testing never popped out of position, and it was stable as a rock and offered an excellent viewpoint during usage. If you have a stem with a very wide faceplate, the computer might be offset slightly and not perfectly centered.

I only tested the 4 Max with the GoPro head and was able to attach my GoPro HERO 4 and Garmin VIRB XE action cameras with ease. It was simple to attach either camera to the low-slung mount though it’s easier to remove the bike computer to facilitate the installation. You also need to reset the action cameras software to shoot upside down since the camera gets attached in that manner. After installation is was easy to adjust the angle of the camera as needed for your preferred shots. I found that shooting with the camera in this location added some much-needed flavor and perspective to the usual chesty and helmet mounted positions.

I was also able to attach my Light & Motion Urban 850 light to the mount since they have transitioned to using the finned style mount.

Bottom Line

The Bar Fly 4 Max is an excellent mount for GPS bike computers. It features a one bolt clamp design, three bottom accessory mounts, a user-friendly Derlin plastic construction and a lifetime guarantee. I primarily tested the 4 Max with the GoPro accessory head which allowed me to attach action cameras and compact lights, making for a highly functional entity. Having the ability to use the 4 Max mount by itself or with any of the three optional accessory mounts makes their system a complete and extremely useful package, and I highly recommend the 4 Max in any of its forms.

They sell the 4 Max mount as a bundle with all three accessory mounts for $39.95.
