Thought I'd chip in with my experience with this.
I've been running it for a few weeks now and my commute is a rural 18km each way.
It does loop recording. Yes, the quesh website says it doesn't but it does. Pretty much take the Cycliq Fly6 manual and go off that. I've not found a feature that isn't on the Fly 6. ie. accident detection at 30deg, auto shutoff, loops etc.
If you've a slippy seatpost, coat the inside of the velcro strap with "Sock-Stop". It's like a liquid latex glue for making the bottom of your socks grippy - like Totes. Available from amazon. Also great for keeping your knee warmers up. Or just buy a rubberised strap. The Fly6 has a rubberised strap for this reason.
The rubber block attached to the light is not a wedge - it's flat so doesn't do anything to change the angle. Pull it off, stick the other wedge shaped rubber bit on to get the camera facing flat instead of up at the sky. The two do not stick together well.
I've had it switch off a few times. I don't think this is a feature of the card speed, formatting or anything like that. It's possible I guess if the filesystem is fragmented from repeated use. However, I reckon the motion detection feature is not detecting motion and switches the thing off. I presume it's a simple wobbly-spring switch and timer. I've not had it switch off if I occasionally hit a lumpy piece of road or just bunny hop every now and again to wobble the spring and reset the timer. If the "feature" could be configured to be switched off then that would solve the one problem for me. I don't need auto shut-off.
It happily takes 64GB cards as long as you format them FAT32. Cards greater than 32GB usually come formatted as ExFAT.
All the guff about it not working with Macs is guff. Works perfectly. Remember to Eject it properly and that when you delete files on a Mac they go to the trashcan. The files are still on the card until you empty the trash.
I'm waiting on a firmware update. I did some brief dissecting of the Cycliq Fly6 firmware (I'm a programmer). I'm interested to see how different it is to the Maxtek firmware. The chip in the Fly6 is a Novatek NT966xx series chip (according to the firmware) which supports h.264 mpeg4, 720p or 1080p scaled and not just the pretty rubbish Motion JPEG AVI format which eats space. I'm hoping they've left some tell-tale CONFIG.TXT settings in the binary such as being able to tweak the exposure/white point, select recording mode (720p h.264 please!) and a few other things which look to be present in both the hardware itself and in the Cycliq firmware.
The Novatek chip is very common in almost every cheap dashcam or action camera and the version used in the Fly6 or I suspect the same in the Maxtek is a good few years old now and obsolete. I'm not sure Cycliq should be that miffed with Aldi when the hardware is essentially an off the shelf Chinese dashcam design that sells for under £20 often. Perhaps there's more to it, but I suspect not.
