I haven't ridden with it yet but the Fly6 came in last night and I had some play time with it. I'll be posting a video later.

I do like the cycling specific features - specifically the incident mode and the auto shutoff.

Auto-shutoff - if it doesn't move for 15 minutes, it just shuts off.

Incident mode - if it tips > 30 degrees from vertical for more than 5 seconds, it assumes there's been an accident - it films for one hour more (regardless of not moving) and then shuts off, so it gets at least an hour before and after the incident.

The taillight is pretty bright - 30 lumens. Obviously a joke next to my DS500 but it's at least as bright as the Hotshot, is comparable to the Pulse 60, and is better than 99% of the lights people actually have on their bikes.
