My Bell Super Air mountain bike helmet (removable face guard) came with an undocumented snap-in GoPro mount. I figured I'd use it to hold a NiteRider light for night trail rides (a relatively common Minnesota activity, we use one bar light and helmet light). This was more of a journey than I expected, so I wrote this up to share.
The first mistake I made was treating the Super Air GoPro mount as removable. It broke and in COVID times it took months to get a replacement. When you snap that thing in don't try to remove it; I think it's designed to safely break under stress.
You can see the mount on the photo below, as well as my light, the NiteRider approved K-Edge adapter ($30 with shipping!, but if you know what to look for you can get it via Amazon for $20 with Prime), the remnant of a Best Tek Amazon adapter (very good except it broke after 3 uses, $10) and "Suptig thumbscrews for GoPro" ($7).
The bottom line is to mount a light on this helmet's GoPro mount you need the K-Edge adapter (their site
, NiteRider site
the Suptig thumbscrews. If you're Amazon Prime you can get both for $27. (I think K-Edge makes a range of GoPro mounts that can be used with NiteRider and this adapter.)
There are limited directions for installation so check out the photo on the K-Edge site; it shows how you orient it in the NiteRider groove.)
The K-Edge is a tough of alloy. You slide it in the NiteRider groove and once you have a good balance point position you tighten two small hex bolts. It ain't coming off without an Allen key.
I actually liked the Best Tek adapter better, it looked like a regular NiteRider mount fused to a GoPro. Sadly it was made using a very inexpensive plastic, didn't slide in and out very well, and the release tab broke off the 3rd time I used it.
Here's the K-Edge with Suptig thumbscrew on the Bell Super Air's Go Pro mount. It's very solid and a great location on the helmet for trail illumination. Of course we have to watch for branches, I've walked lights more than once.
