A few years ago I thought I could get around the problem of poorly functioning mirrors on my Jota by using a rear-view helmet.
I road-tested of those "Reevu" motorcycle helmets. They have a view port above the front opening that contains a bunch of optical gubbins that allows you to see out of a little window in the back of the helmet. Seemed like a good idea but the optics were pretty rubbish. The view was distorted and the focus wasn't very good. It was hardly an improvement on the bike's mirrors so I didn't buy it. I still think it's a good idea, but needs a bit of development in the optics department. I reckon they need to team up with a manufacturer of binoculars.
There's also the X1 Cross helmet that uses a rear view camera and a heads-up display so you can see what's behind you. Never seen one of those in the flesh so can't comment on their functionality, although it seems to me an overly high-tech solution for a simple problem. Online reviews are a bit mixed.
I reckon rear view helmets are at best only a supplement to mirrors. Not a replacement. I don't reckon a rear view helmet would obviate the legal requirement for mirrors fitted to the bike anyway.
I ended up getting some Oxford bar-end mirrors that gave a good view past my arms and don't vibrate much at all. Link here:
Oxford mirrors.
Not long after fitting the Oxfords, the bike fell off the stand and demolished one of the mirrors. So I bought some cheap Chinese knock-offs on eBay for a fraction of the price that look identical and work just as well. They were so cheap I bought two sets so I'd have plenty of spare parts if that happens again. Of course it hasn't so I still have the spare set.
The obvious negative point with bar-end mirrors is that they make the bars wider. That can be an issue if you do a lot of lane filtering. Also, because they stick out beyond anything else, they're always getting bumped out of alignment when walking past the bike in the garage (my garage is a bit cramped - too many bikes). There's also the falling over issue mentioned above.
I presume Atlas bars are quite a bit wider than Jota bars, so the bar-end solution may not be practical. I can imagine them getting wiped out on trees if you take the bike off road.
